Antarctic Peninsula Climate – A Change in Krill Ecosystem
Antarctic Peninsula Climate – A Change in Krill Ecosystem
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Helping Kids Care For the Earth – Ideas For Earth Day and Beyond
Helping Kids Care For the Earth – Ideas For Earth Day and Beyond
Earth Day is April 22, and while it’s important to get involved on this day, there are things we can do as families that will make a huge impact throughout the year.
It starts with helping our kids to celebrate the world in which we live, and it continues with helping them to love it so much that they want to do everything they can to help protect it. Here are six ideas to help your kids celebrate and care for our earth:
1. Get out and enjoy it. Researchers are now saying that simply getting kids outside in nature may be the most effective way to raise their awareness of environmental issues. Suddenly, these problems that they hear about on the news and in the classroom have a real impact on their daily lives. They see firsthand how a forest or a beach or a tidepool or a meadow is teeming with life, with ecological relationships that are interdependent, delicate and complex.
To encourage your kids to get out there and enjoy the natural world, you may have to purposefully inject some extra excitement in the idea, but just at first. Take your dog (or a friend’s dog) for a walk in the woods. A dog’s love for nature, and subsequent enjoyment of it, is infectious. Create a list of things to find and make your adventure into the outdoors into a scavenger hunt.
If possible, and if your kids are old enough to be by themselves out there, find a safe place for them to play in a natural environment. Allow them to go there to get away, to sit and think or to talk with their friends. Make a point to get the kids out in nature every day. Better yet, go with them.
2. Watch “An Inconvenient Truth” as a family for inspiration. Invite some of your children’s friends over to watch it with their parents and talk about some initiatives that you can each commit to or some larger projects that you can work on as a neighborhood or community.
3. Help your kids learn about endangered animals. Together, look into organizations that help endangered animals and see how you can get involved.
4. Reduce and re-use, then recycle. Lots of kids get excited about recycling. Fewer are into reducing or re-using. Model to your children a healthy pattern of consumption. Talk frequently about the many benefits (which go way beyond environmental) of living a simple life and of being wary of a lifestyle of mass consumerism. As kids spend more time outside and less time at the mall or watching television advertisements, this shift may feel increasingly more natural to them.
5. Teach your kids about potentially harmful chemicals and how they can be everywhere in our world: in the foods we eat, in the supplies we use to clean the house, in our paint, in our cosmetics, in our lawn care products. Turn the search for these things into a game and allow your kids to be detectives, learning about and seeking out these harmful chemicals and then finding natural alternatives.
6. The next time you take the kids to the grocery store, see how you can minimize the amount of packaging that you purchase. We have been known to purposefully not purchase an item because of the manufacturer’s use of wasteful packaging. It won’t take long for the kids to realize that the best item in the store for minimal packaging: raw fruits and vegetables.
In our family, the more we can make these life changes into a game, the more apt the kids are to follow suit. Help your kids to understand how one person really can make a difference (especially when that person is part of a committed family or group) and review often the personal impact that you all have made.

A Huge Birthday Party! Giving Our Planet a Big Presenet on Earth Day
A Huge Birthday Party! Giving Our Planet a Big Presenet on Earth Day
If you have a computer, imagine how you could make a difference!
How you say?
That is all I do, show others how to promote Earth day with a Professional Events Marketer that is sharing their knowledge specifically to get an important message out. Just imagine sending one note, or just telling a friend or colleague your business Supports Earth day!
It is not just about prestige it is about you creating value in your network. When you are seen to have a heart, this is attractive to people in all lifestyles. This can make your businesses look very good. Its attractive seeing a business you are involved with supporting a worthy cause!
Let me explain.
We have created Groups that are Non-profit just for helping with education, one is called Recycling Renegades, 10×10 at Face book and we have used many services that many do not know are there but used them strategically to spread the message about Earth Day. We are just getting the word out that Earth Day can Help Corporate create a better image.
To make it worthwhile for a businessperson to get involved, we have managed to get a great set of training on Social Traffic Media to get them interested in helping us with Earth Day.
Just look at the Fun we are having, but I have to say, it is a very serious message. Its not taken lightly as its global warming, pollution, rain forests rebuilding, forestry’s, clean ups on oil slicks and more. We have demonstrated our dedication with the work going into promoting Earth day and all the people fulling you tube channels and other Medias, just to get the word out about earth day, we are taking this serious.
Warning, it is not pretty! What is happening to this earth has been hidden and covered up, please if you have a weak stomach do not look and investigate.
Now look at all the Professionals that want to be part of this big picture and give a little time to learn better skills and Promote our Earth.
If over 2000 People see the Value, will you? Many together can make a loud voice for earth day do you not think it would be exceptional for your business to be involved in such a momentous occasion.
Get with it or be left behind, it is a simple decision!

Sea Levels Rise
Sea Levels Rise
It is no new scientific fact that there is a slow steady increase of temperature; we’ve been studying and recording changes for a few decades. For some reason people are only now starting to take notice of how desperate the situation is.
Due to the increased temperature, sea levels are on the rise. It now is easier for boats full of scientists to access the Northwest Passage for research due to the polar icecaps melting . Areas that were once almost unreachable are now becoming navigational and the search for precious gems, gold, and oil is on! There is no end to mans greed.It makes sense that when the sea levels rise the ground surfaces slowly disappear. We will lose our agriculture farmlands. There may not be enough food needed to sustain ourselves, let alone other countries that we already support. Many farmers will lose their farms and their lifestyle.
Should sea levels on the rise be a worry about freshwater? Our drinking water is not a luxury it is a necessity and is as important for people, plants, and animals. The possible damage to freshwater due to rising sea levels should be a major worry to all of us.
For hundreds of years polar bears have been the king of the Arctic ice and roamed over vast areas of icy tundra. But with the icecaps melting away, and the distance between ice flows becoming greater, many polar bears have drowned from exhaustion before reaching shore. It also makes hunting their primary source of food, the seal, more difficult. Dying of hunger is now a probable fate for many of them.
The total extinction of many of the world’s beloved land animals may be just around the bend due to rising sea levels.

Aqueduct For Florida A Modern-Day “Roman” Germ of an Idea
Aqueduct For Florida A Modern-Day “Roman” Germ of an Idea
The west coast of Florida remains trapped in an ongoing drought. In Pinellas and Hillsborough Counties (Tampa and St. Petersburg/Clearwater) severe restrictions on water use are in place. Even the use of reclaimed water for lawns and gardens is now restricted. The rainy season is not yet here; but in past years the amount of rainfall received during the wet months was far below the historical average, so that reservoirs and ground water supplies have never had a chance to recover.
The situation is quite different in northern Florida, in the Panhandle and all across the State close to the Georgia border. The weather in those parts of the State is generally wetter, and more consistently so, than the weather farther south.
Yesterday, our local St. Petersburg Times carried a story (with photographs) of the damage which is now being inflicted in Madison County (which borders Georgia) by floodwaters from the Withlacoochee and Suwannee Rivers. The storms which produced the rain moved from west to east across the Panhandle over the past week, to the point at which the Withlacoochee crested at 89 feet, four feet above the record set in 1948. So far, the rising floodwaters have destroyed or caused severe damage to almost 200 homes and lesser damage to 500 more, all areas combined. Two people are known dead, and one person is missing.
Quite apart from the possibility of reducing the tally of deaths, personal injury, and property damage which even a partial remedy for river flooding in these areas might entail, it boggles the mind just to consider the sheer waste of so much fresh water. Most of that damaging flood water will be gone forever as it eventually finds its way to the Gulf of Mexico. That’s a shame, because so much of it could be put to good use in the west coast, central, and other parts of the State where it is so desperately needed. The waste is not just limited to damaging flood waters, either. The “top of Florida” is blessed with more rainfall, on average, than it needs. Obviously, the flow of river water into the Gulf represents a volume of water which has not been put to good use.
In passing, we acknowledge that the flow of a certain amount of river water into the Gulf is said to be necessary for the health of the shellfish beds near the coastline.
Even so, it seems inadmissible to stand by and do nothing but watch a surfeit of water in the northern counties lay waste and then go to waste while there is such a great need for water in other areas of the State. Surely there is a partial remedy which might ameliorate the problems in the affected sections.
The Romans found a way to move big volumes of water over considerable distances. Surely we can build on their success – and on successes over the centuries since that time – by constructing an Aqueduct system to bring excess water from the northern Florida counties to drier areas to the south.
The best part is that the right-of-way is already in place! It’s called Interstate 10 and Interstate 75. Take a peek at a map of Florida. Find the intersection of I-10 and I-75. The Suwannee and Withlacoochee Rivers are close by, as are other rivers. There are others to the west, and I-10 probably crosses every one of them.
Excess water could be fed into the Aqueduct lying above-ground or underground in the median of I-10 at various points along its route, and then fed south toward Tampa and St. Petersburg/Clearwater in that part of the Aqueduct lying within the median of I-75 and I-275. Do you see how obvious that is?
If ever there was a perfectly-planned right-of-way for a particular purpose, although not part of the design at the outset, this is it.
There would be hurdles. There always are. Will and determination were invented for the purpose of overcoming hurdles.
It seems to me that the construction and operation of The Florida Aqueduct is an undertaking which private capital should undertake. It need not cost the State a penny.
Let’s see whether anyone steps up to the plate.

Scientists Ask For Higher CO2 Cuts at Copenhagen’s Spring
Scientists Ask For Higher CO2 Cuts at Copenhagen’s Spring
The International Scientific Congress on Climate Change was held in Copenhagen between 10th to 12th March and organised by the International Alliance of Research Universities (IARU): the conclusions will be published into a full synthesis report next June. Almost 1,600 scientific contributions of researchers from over 70 countries have been received, and more than 2,500 delegates attended the event.
Connie Hedegaard, Minister of Climate & Energy of Denmark said that we have “to avoid the unmanageable and manage the unavoidable” and she pointed to their example: this European country has become a net energy exporter in 30 years, creating a green growth as a stable solution of the 70s oil crisis. The messages of the congress are various. The risk that current trends of the climatic system will accelerate has a more defined and significant meaning: more probable abrupt and irreversible shifts, and we are already above the worst scenarios published by the Intergovernmental Panel on Climate Change (IPCC) in 2001. Thus the big problem is trying to at least slow down these trends if not reverse them. The experts tell us that fast regional and global mitigation strategies are needed and that the more we wait the more expensive and ambitious actions will have to be taken in the future. The fact that scientists have come to the point of saying that “Inaction is Inexcusable” means also that people who studied relentlessly for decades are frustrated by the inaction of governments, businesses and people: it is understandable given that their work has not been considered and used enough, if not at all, up to now. They are speaking louder and clearer now. The different roles of politicians and scientists have to be combined. It is time for leaders to rely firmly on science as a basis for tough and unavoidable decisions. A “societal transformation” is being asked for by a wide group of the most intelligent people on the planet including diffusion of sustainable behaviours, innovative leadership, removal of subsidies and reduction of “vested interests”. These are all very explicit messages to politicians and public alike: there is a lot of work to do between now and next December’s COP15.
In the final debate the Danish Prime Minister, Anders Fogh Rasmussen, summarised the six messages given by scientists as 6 keywords: Urgency (of the climate change challenge), Direction (long term target to be defined), Action (short term targets to be set), Fairness (to the poorest and most vulnerable), Opportunity (to originate large benefits), Governance (creation of a new global multilateral era). He stated firmly that “Business As Usual is dead” and asked his colleagues to follow Obama’s call for a Green New Deal, already asked for by public opinion and by many political parties in the world.
After the final debate with the panel of scientists an impatient Rasmussen asked for clear words on the CO2 emission target to be set in the new treaty. Prof. Daniel Kammen, Obama’s Senior Policy Advisor, stated that an entire new industrial revolution is needed to cut 1990’s CO2 emissions by 80% in 2050 and Prof. Stefan Rahmstorf agreed on this point. The feeling was that the other panelists didn’t mind… At this point the Prime Minister concluded that the ambition for COP15 can be this -80% long-term objective following the precautionary principle to avoid worse impacts (than the ones presented in 2007 IPCC report) already hypothesized by new works. Overall a more direct communication between scientists and policy makers took place in this huge meeting: now it’s time for delegations to study and prepare the ground for brave steps forward to be made by the international community in Copenhagen’s crucial Conference of the Parties #15. Will we be able to navigate better our “ship” in the solar system during the over 200 rotations it will make before then?

Climate and Biodiversity For Common Good
Climate and Biodiversity For Common Good
Concerns about dangerous climate change and large biodiversity loss are visible throughout the world: unprecedented rates of temperature increases and species extinctions are a reality. In 1999 Dr. Peter Raven, president of the International Botanical Congress, published a paper in which he states that “current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue. At this rate, one-third to two-thirds of all species of plants, animals, and other organisms would be lost during the second half of the 21st century, a loss that would easily equal those of past extinctions”. He then outlined seven “Points to Slow the Extinction of Plants”, including financial and capacity building instruments to help developing countries protect 80% of the world’s biodiversity they host. As far as climate change is concerned, the responsibility of developed countries is high in providing the most threatened regions in the world with good instruments to cope with this challenge (or at least examples of them to implement autonomously).
Climate change plays a significant role in this human-induced mass extinction because it is increasing the already large biodiversity losses caused by habitat destruction and fragmentation, water and air pollution, introduction of invasive species. Marine ecosystems will be affected by an increase in sea temperature, but also by ocean acidification, because of the higher concentration of dissolved carbon dioxide (carbonic acid): in fact this reduces the shell formation ability in many organisms. Polar (and mountain) ecosystems are particularly vulnerable to climate change, with effects such as thawing permafrost, decreased snow cover, losses from ice sheets and changes in ocean temperatures. Large impacts on Arctic biodiversity are already evident, pictures of polar bears wandering lost on small icebergs being a scary and sad symbol of the era we live in (even former U.S. President Bush, at the end of his mandate, recalled this image to show his fellow citizens he cared about climate change …)
In this rapidly changing environment it is therefore extremely important that conservation plans include adaption measures for ecosystems accordingly to the predicted regional climate patterns (but models need still to be improved a lot at this scale): dynamic approaches are needed to set good options for future ecosystems and landscapes. It will be necessary to facilitate the movement of species to new geographical locations, as they follow the shifting habitats.
The public concern is growing: in Africa last 28 February young people organized a march from impoverished urban areas to the summit of Mount Kilimanjaro to raise awareness on climate change, together with the Kilimanjaro Initiative and the UN’s global UNite to Combat Climate Change campaign. It seems though that the global attention on climate change doesn’t fully consider implications for biodiversity yet: while the negotiations and speeches on climate issues are very popular (and the Nobel Prize was awarded to the entire IPCC together with Al Gore in 2007) the meetings and decisions of the Convention on Biological Diversity (http://www.cbd.int/) don’t raise comparable interest. Is it because the anthropocentrism is (still) the prevailing philosophy and animals and plants are mainly seen by people as beautiful “supporting actors” on the planet we live on? Right when we are losing control of the global situation it is probably time to reflect on our role of dominant species and acknowledge the fundamental contribution of other organisms to our livelihoods, despite many of us live in the so called Technosphere.
Policies to protect the climate avoiding irreversible effects on the ecosystems need to be strongly interconnected with conservation strategies: preserving natural areas while helping them adapt to the changing climate means hopefully to leave better, or not as compromised, ecosystems to future generations. Climate and biodiversity, though ever changing and evolving, are common goods and they need common policies: if we reduce the human Ecological Footprint both the atmosphere and the biosphere will be better off (and our children and grandchildren living in them).

The Ecological Footprint is a measure of human demand on the Earth’s ecosystems. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Using this assessment, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle. For 2005, humanity’s total ecological footprint was estimated at 1.3 planet Earths – in other words, humanity uses ecological services 1.3 times faster than Earths can renew them.

Christians Earth Day
Earth day is coming soon (4/22/09). This month we have Easter as well…so it got me thinking. How should Christians respond to Earth day?
First, I think we need to keep it all in perspective. Yes, we are to be good stewards of the planet. However, we are not to be earth “worshipers.” The earth is just another thing in our lives that God wants us to be a good steward with. Yes, it is important…However, Jesus Christ and His shed Blood is much more important. Saving souls should be above saving polar bears. You know what I mean?
So, do I think Christian’s should celebrate Earth Day?
Sure. Just make sure you have this whole eco, green planet stuff in perspective. Make sure that you are lined up with the Word and that God is your priority and His will. Do not let being green override sharing the Love of Christ and your true God-given purpose.
All that said, I thought it would be cool to add some fun stuff to do for earth day…
Earth Day Activities:
Plant a tree. This could be a fun family project.
Recycle. Take those cans you have been saving and turn them in.
Make the whole day green. Make eco choices all day long.
Clean up. Take your family to the park and clean up the junk left by others.
Make a point to add more green. Add at least one more green activity to your life.
Go on a nature walk. Enjoy the beautiful environment that God created for you.
Organic. Visit your local Ma and Pa farmer and shop for some earth friendly stuff.

Always Rely on Professionals of Wind Turbines is Very Important Proper Installation
Always Rely on Professionals of Wind Turbines is Very Important Proper Installation
The most efficient and economical way of using wind power to light up your home is to install a windmill or wind turbine as they are also called. The current trend is to use green energy to supplement energy generated from fossil fuels to ensure uninterrupted supply and protection of the environment.
Wind turbines of different sizes are available for your different requirements. If you live in an area where the average wind speed ranges around 10 to 12 miles per hour, you can install a wind turbine to generate electricity throughout the year. Depending on your energy requirements, you can opt for the right sized wind turbine starting from 2Kw units to even 20 Kw units.
Choosing a wind turbine manufactured by a reputed maker is essential but your task does not end there. You should choose the right contractors for installation of the wind turbine. Proper installation of wind turbines is very essential because of the following reasons.
• Installation of a 42 feet or more structure is not a simple task. The installation must be perfect to ensure that there are no safety concerns. Even the smallest flaw in installation can have severe consequences.
• A wind turbine may look like nothing more than a fan attached to a long pole. However, it is a complex and delicate mechanism that can be damaged with careless handling and improper installation. This can render your entire investment totally waste.
• The fans of the wind turbine may seem to be revolving very slowly from ground level. However, the height and the weight of the fans combined with its velocity can cause a lot of damage if breakage or other malfunction occurs.
• It is common to make use of the land beneath a windmill for other purposes. If you ensure that the wind turbine is safely installed, you can set up structures under the wind turbine without any fear of accidents and injuries.
• Setting up a wind turbine for your home will ensure that your energy requirements are taken care of forever. However, this requires a high initial investment. Improper installation will mean that your entire investment goes waste without sufficient benefits. What is the point of sinking thousands of dollars into your windmill if it conks off within a few days and you have to spend more repairing a faulty installation?
Hence, you should always deal with professional wind turbine contractors who know what they are doing. How to identify reliable contractors from all those who claim to be the best? For starters, all professional contractors who take up such projects of green energy offer a free quote. They do not charge for a quote which helps you estimate the cost of the project. Rather, they would be more than happy to offer the quotes for free.
Another way to identify professional service providers is to take a look at the spares and materials they use. Professional wind turbine installers will never use counterfeit material to reduce cost.
They follow strict safety codes and comply with all professional standards at all times. The net result of dealing with such installers for your green energy requirements is that you are assured of the best service at all times.

GM Foods Against
GM Foods Against
Genetically modified (GM) foods are not being found to be safe for humans, or for the environment. There are a number of reasons why there a growing number of people are against GM foods. Are Genetically Modified Foods Safe? The reason to resist the growth of GM food in our diet is that it has a negative impact on our environment; plants and animals grown organically are not distorting their genetic makeup.
And in the rush to accelerate the production of genetically modified foods, scientists are short cutting testing methods. Recently, the United States Tufts University, School of Medicine was involved in testing the effects of genetically modified rice directly on children (by-passing the usual practice of testing on animals). This direct testing on children created controversy and a formal letter of protest from 22 international scientists to the University; the protest letter has been made public through various social media.
The letter protested the use of children as a breach of medical ethics code since children cannot legally give their consent (since it is not deemed to be informed consent) to participate in experiments. As Professor David Schubert, Salk Institute of Biological Studies said, “…it is completely immoral to feed this rice to children without proper safety testing … [i]t’s like putting a new drug on the market with no toxicology or safety trials”.
In defense of their position, the Golden Rice Organization issued a press release that states they “…us[ed] the correct Chinese and US government approved processes, the trials in China went ahead last year with the formal approval of their parents and the understanding of the children”. How do children understand the impact of genetically modified food on themselves or the environment? It’s a complex subject that many adults have a hard time understanding. Also, how can anyone (parents, children, or testing scientists) understand what the long term effects of genetically modified “golden rice” are on the human body without prior study or testing?
More importantly, will the overall risks of genetically modified foods over time out weigh the alleged benefits? Farmers have cross-bred plants and animals for hundreds of years to improve their products. Improvements to size, produce yield, taste, hardiness have been achieved through relatively natural means and within nature’s own boundaries; different species were not bred together.
With the discovery of DNA and a method of gene extraction, the concept of genetic modification was born. The intent of genetic modification is to create food that grows quickly, yields much, is resistant to pests, to disease, and to other natural events. However a number of scientists respond that the benefits are not worth the risks; genetically modified foods often become resistant to herbicides and pesticides requiring ever increasing amounts. There is the suspicion (still unproven) that pollinating bees have been affected by the increasing use of these chemicals and that both pollinator and predator species have been affected by the genetically modified crops (also known as transgenic crops) through habitat destruction and use of dangerous herbicides and pesticides.
Since the introduction of genetically modified foods, some scientists are reporting that food-related illness has increased. The only published human feeding study confirmed that genetic material in genetically modified soy transferred into the DNA of intestinal bacteria and continued to function. What long term impact will these foods have on the population and the environment? There are many more potential risks in the development of genetically modified foods. Animals that were fed genetically modified feed appeared to suffer from increases in fetal death, low birth weight, sterility, and more. The concern is that human reproductive failure and sterility or infertility will be long term consequences to using GM foods.
In the US, the Department of Agriculture reports that cotton and corn crops have been genetically modified to produce their own Bt toxins since 1996. Bt modified crops are insecticidal crystal proteins and are considered effective against crop-damaging caterpillars. The toxins are considered important for pest control and since resistance to herbicides and pesticides is growing, the sentiment is that these genetically engineered Bt toxins will help to protect the crops. The issue with the GM Bt toxins is that they are considered serious allergens; ever wonder why so many more children and adults are exhibiting allergic reactions than ever before?
The problem with genetically modified foods is that there is also a reaction for the action; unfortunately, globally, in our rush to grow food supplies, we have not taken the time to properly test and research the long term impacts and effects of genetically modified foods. It is easy to be against GM foods - our planet is at risk.
