Green Shopping Basics
Green Shopping Basics
Going green always starts with good intentions, but the massive amount of green terms can sometimes be overwhelming. Here’s some of the common green terms you’ll hear and what they mean.
Organic
The term organic can often be used very broadly, but typically refers to products that have only organic components, produced without pesticides, herbicides, insecticides, or fertilizers or other harmful chemicals.
Look for: USDA Certified Organic
Sustainable
Products or materials that are described as being sustainable contain materials that do not deplete the Earth of its resources and is easily replenished. There are many common types of materials that are considered sustainable:
Bamboo - Bamboo is a fast-growing and renewable resource that can be used to make fabrics, flooring, furniture and other products.
Jute – Jute is a long and shiny vegetable plant fiber that can be woven into a strong thread or twine. It is commonly used to create cloth or used within carpets, and rugs.
Hemp – Hemp is a fast-growing plant that is most commonly used for its strong fibers to create cloth used in bags and clothing. It can grow organically and also be used to create oils for cosmetic products as well as be used in food.
Sustainable Wool – There are many types of sustainable animal wools such as alpaca fibers or merino wool that can be used to create strong fibers commonly used in clothing.
Energy-Efficient
Products that are energy-efficient are design to consume less energy when operating without sacrificing performance, reducing long-term environmental and cost impacts. Energy-efficient products can range from appliances to light bulbs as well as contain different levels of efficiency.
Look for: Energy Star Qualified, EPEAT Rated
Post-Consumer Recycled
Once a product has completely served its purpose, what remains are post-consumer materials that would otherwise be disposed as waste but are instead recycled. This would include products such as old packaging, glass bottles, aluminum cans, and plastics. When you recycle from your home these products become post-consumer recycled.
How is this different vs recycled? Regular recycled materials can contain a combination of materials, often coming a scraps or other by-products as a result of manufacturing. This could include both pre-consumer and post-consumer waste.
Recyclable
A recyclable product means that it can be recycled and be used to create future products. Polypropylene #5 is a common plastic to look for in products which is one of the most easily recyclable plastics.
Look for: Polypropylene #5
Reusable
Reusable products mean that a product can be used multiple times before the product is discarded or recycled. Some common reusable products are shopping bags, water bottles and tableware.
Fair Trade
Fair Trade is a social movement that promotes certain standards of sustainability practices and empowering producers in developing nations. Fair trade supports fair prices, fair labor conditions, community development and environmental sustainability.
Volatile Organic Compounds (VOCs)
VOCs are organic chemical compounds that have high vapor pressure and easily evaporate at room temperature. VOCs can be released from many household items such as paints, flooring, upholstery, and cleaners. These VOCs are not only air pollutants but have also been known to cause health effects as well.
Look for: Low-VOC, Zero-VOC
Bisphenol A (BPA)
BPA is an organic compound that is used in the creation of many plastics and resins. Most commonly you will find BPA used polycarbonate bottles. While there is some controversy about the effects of BPA, some research has raised serious health concerns about the usage of BPA.
Look for: BPA-free
Biodegradable
Biodegradable means that a substance can be naturally decomposed by biological processes. If a product is biodegradable, this means that it can be disposed of with no negative environmental impacts.
Solar-Powered
Solar powered products are powered using energy from the sun. Solar power can be used in a range of products from small household gadgets to entire home heating systems.

Paper Bags Can Substitute Plastic Bags?
Paper Bags Can Substitute Plastic Bags?
Bags hold an important place in our lives. They are sometimes referred to as the best personal carriers. They are made of various stuffs like cotton, synthetic, leather and so. But when it comes to general usage like for shopping, the names of two types of bags viz. plastic made and paper made bags come to our intellect. Both are fine, but the question is, which one is the best suited to our requirements. Lets discuss the peculiarities related with the two.
You might be thinking that paper bags are not as durable as those made of plastic. Also, we see that the latter are more commonly used than the former one. But, do you know plastic is a stuff which is really hazardous to the environment. It takes thousands of year to decompose. If burnt, it emits poisonous gases which again pollutes the environment. If buried in the ground, it makes the soil infertile. If thrown in the sea, it pollutes the sea water and proves to be a threat for the life of the sea creatures. One can imagine, how hazardous is plastic to our planet.
This perilous nature of plastic had forced the governments of many cities of the world to put a ban on the use of poly-bags, which are a major source of plastic pollution. Few cities of the world in which these polythene carriers are either completely or partially banned include San Francisco, New York, Texas, Germany, Dhaka, China, Kenya and Ireland to name a few. Even the government of Delhi had issued guidelines against the use of polythene. However, later on the government changed its decision to completely ban the polythene, due to some reasons. Government suggested the manufacturers to set up the recycling units on the basis of “polluter pays principles”. But the government has not completely given up the plan to ban these polythene carriers, it is in the pipeline.
In this context, paper bags are the best option. No doubt, they are unconventional, but they are eco-friendly and easy to recycle. Nowadays, there are various types of paper made bags available in the market. They are not only good looking, but also have ample of space to carry goods and are quite durable. The handmade paper bags available nowadays are designed to suit specific requirements which include carrying gifts, carrying wine, shopping etc. There is a separate bag to serve each purpose. Although, multipurpose bags are also made from paper. They are proving to be the best substitute for plastic or polythene carriers in the modern context.
Now, as we have told you every significant fact related to plastic and paper bags, It’s upon you which one to choose. The hazardous and non-disposable polythene, or the environment friendly and elegant paper bags.

Go Green With Natural Finishes
Go Green With Natural Finishes
Finishes are coatings that are applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear. They also improve the appearance of the structure and are used to enhance the design of rooms.
Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource. There are now paints and finishes on the market that are derived from a renewable resource, which in a small way, helps to reduce dependence on oil, and contributes to a more sustainable world.
The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD). This increases the burden on waste treatment facilities, and can also pollute our natural water sources. In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.
When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world. And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.
Low and no VOC paints have less smell and less impact on air quality. EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.
Switching will not cost you more. Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused. The paint is still washable, and is far less harmful to you, your pets, and the environment.

Climate and Biodiversity – Common Policies For Common Good
Climate and Biodiversity – Common Policies 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.

5 Steps to a Greener Life
5 Steps to a Greener Life
Lots of people talk about trying to live a greener life, with some even going so far as to completely change their lifestyle, but most people aren’t sure how to go green because they don’t know exactly what that means. Sure, most people know the basics that scratch the surface such as reusing, recycling and reducing the amount of waste output for their homes but there many other steps you can take to move towards a cleaner, greener environment.
If you’re wondering how you can make your life greener, here are five different tips that are simple and easy to implement and that don’t cost the you anything. All it takes is a little dedication and after a few months, these five little things will become second-nature to you.
1. The next time you go shopping use cloth bags at the grocery store instead of paper or plastic. These cloth bags can be purchased for as little as a few dollars each and they’re much stronger than paper or plastic bags and will last you through years of use.
These bags help reduce waste since most people throw away the plastic and paper bags. The hardest part of using cloth bags is remembering to take them to the store, but once you get in the habit of using them, it becomes unconscious habit.
2. Replace your standard light bulbs with compact fluorescent bulbs. These bulbs use less energy and last for four to five years, almost 15 times longer than traditional bulbs. While the cost of a compact fluorescent bulb is more than your standard bulb, they easily pay for themselves over time requiring less frequent replacement and reduced energy consumption. In fact, studies show that a CF bulb can actually pay for itself within one to two months. One CF bulb also saves about five pounds of greenhouse gas carbon dioxide a month. Replacing every bulb in your home can have a huge impact on the environment and on your wallet.
3. Use public transportation. By car pooling, taking the bus, or using the subway you can cut down on the amount of gas you use and the amount of exhaust your car emits. While it may be an inconvenience in some ways, it is one of the best ways of helping the environment. Even better, walk or ride your bike to work if possible. This not only saves you money and helps the environment but it also keeps you fit and healthy!
4. Adjust your thermostat by a few degrees. By turning your thermostat down by just two degrees in the winter, you can save over 50 pounds of greenhouse gas carbon dioxide per month while lowering your heating bill. Turning it up a few degrees in the summer can likewise save you money and save the environment.
5. Finally, only wash your clothes or run your dish washer when you have a full load. It wastes water and electricity to wash and dry only a few pieces of clothing. In fact, if you can, try to wash your clothes using the cold water cycle as it uses up to 50% less energy than a warm water one.
By just doing these basics not only you can save some serious money but you can rest assured that you’re doing your part for a cleaner, brighter future. To discover more ideas you can use around your home for living green visit http://www.greentipsforyou.com!

The 3 R’s – Our Family’s Commitment to Do More
The 3 R’s – Our Family’s Commitment to Do More
So How You Do’ing? In the spirit of recycling, I thought I would use those famous words from Friends character Joey. I have shared with you in other articles ideas that my family are using to cut our carbon footprint on this precious Earth that we call home.
Reducing is always a challenge, because it goes in the face of our societal values of having more and doing more, but it is the highest form of recycling.
Re-using is something that has been natural for me through out my life. It may be challenging at times to creatively transform old household items into new uses, but this has become one of the staples of our family’s efforts to be more environmentally friendly…and save money.
Recycling has become the catch phrase for the 3 R’s, but is strictly speaking altering one thing into another. It is important that we recycle as much as we possibly can, because making consumables from recycled goods is always cheaper and better for the environment than making them from raw materials. But we should recognise too that recycling should only be used after we have reduced and re-used. For our children and their futures, we must use all the arsenal of tools embodied in the 3 R’s: reducing wherever we can, re-using everything that we possibly can, and recycling every item that our councils and recycling centres will accept.
Today I am wanted to look at those things that my family could do better:
1) Reducing excess packaging. I think this might be the most challenging to tackle; partly because a great deal of it is beyond our control. We are, I admit, large consumers of electronics (blame techie husband). Have you ever noticed how much packaging goes into one tiny piece of plastic? A memory stick that is one inch by two will most often come in a plastic (non-recyclable) package with a large cardboard inset and an information packet. I recognise that this is an anti-theft device, but aren’t there other alternatives? What about putting such items behind the counter? The other side of that is that the packaging contributes to the cost of that piece of plastic and metal. Of course, this is an issue that will require a concreted effort from consumer and most likely government intervention to address. What I can do for now is to choose to purchase my fruit and vegetables loose. I am also hoping this will cut down on both spending and waste by purchasing only what we need.
2) I am going to remember to use those little switches on the power plugs. As I mentioned, being American we do not have such things. It has been hard for me change a lifetime of habits. But with my husband’s help, I am going to use these magic little buttons more often.
3) We are going to replace all batteries with rechargeable ones. About half of our batteries are rechargeable; mostly the ones in our keyboards and mousse. But over the coming weeks, we will replace all batteries with rechargeable ones…since these are particularly toxic waste in our landfills.
4) I am going to use less water when washing dishes. I have this habit of running the water to rinse dishes as I go. The new plan is to wash everything and sit it on the counter until I am done. Then use the same pan to rinse the dishes in cold water.
5) I am going to have a spring clean out. I may be doing pretty well at re-using but I could help others to do better by donating all the stuff I am not using to Freecycle, the Islington Swap Xchange, or my local Mind shop. This will make my husband very happy as he has been complaining about my daughter’s toys for a while now.
So what can you do better? Remember though this is not about being perfect, but the little things that we can realistically do and continue to do. The things that may seem so small that you don’t think they will make a difference: things that if we all did would make a huge difference. I invite you all to share your list with me.

A Change in Krill Ecosystem
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.

Recycling Helps Prevent Global Warming
Recycling Helps Prevent Global Warming
If you want to keep the environment clean then you need to recycle everything you can. You should set aside a few spaces so that you can keep your recyclables in a separate area. All of your water bottles should go into one container so that it will make it easier for you to take them to the recycling center. Also you need to make sure that you recycle all of your chance and glass bottles as well because this will also help the environment. Many people do not know that you can also recycle your old newspaper, you can call to have it picked up each month.
If we are going to prevent global warming than one way that you can take part is to recycle everything you use. the best thing you can do is educate yourself on the best way that you can recycle all of your throwaway items. Maybe some of your old clothes can be donated to Goodwill this way they can be recycled and used again. Make sure that you try to avoid using plastic bags from the grocery store because once they end up in a landfill they can cause a lot of problems. Once you have started a recycle program in your house you will find that it is easy to do.
Remember that if you want to improve the environment you need to recycle everything you can. It always works better if you have specific containers that you use for each of your recyclable items. Once you make a few small steps towards improving the environment you will feel better about yourself.

The Pine Beetle in Canada
The Pine Beetle in Canada
For some time now, the extremely destructive Pine Beetle ( Dendroctonus ponderosae ) is ravaging huge areas of Canada’s forestlands and its destruction is so virulent, that it is leaving massive and easily visible scars across otherwise green foliage landscapes. In numerous areas where the pine beetle is active, various solutions for its eradication have been tried and some of these in themselves, are so toxic in nature that they would normally be classed as being a larger risk than the beetle they are attempting to destroy.
These beetles have an average life span of about one year and generally, their eggs are laid through the bark of a tree where they develop into larvae that stay under the bark all through the winter months. During the spring the larvae continue to feed under the bark and then they will change into pupae during the months of June and July. During the rest of the summer and into fall, the new adult pine beetles leave the infested tree through emergence holes they create and after drying themselves in the warm sunshine, they take off to mate and commence a new cycle by laying the next generation’s eggs under the bark of new trees.
During the time they remain under the bark of a tree, they are known to transmit a fungus type substance that stains the sapwood of the tree a blue colour. Other than discoloration, this blue colouring appears to have no adverse affects on the actual structural integrity of the tree. However, we must not forget that the damage has already been done and like a rolling snowball, it gather momentum and range of spread with each summer that comes. These beetles prefer mature trees such as lodge pole pines which are considered mature after eighty years of growth and in the Province of British Columbia, current statistics show that there are three times more mature lodge pole pines than they had over ninety years ago. Hot and dry summers make the trees more stressed and thus more susceptible to attack and infestation by this ravenous little creature. Trees which have been attacked will turn red roughly one year after the infestation and then, between one and two years later the affected trees will turn grey and all of their needles will fall off.
Another interesting fact about these little guys is they do not like it too cold! Their eggs, larvae and pupae are very susceptible to very cold temperatures and if these temperatures remain below minus 35 Celsius for a prolonged period of maybe a week, then this will kill off the eggs, larvae, pupae and generally sizeable portions of the beetle population in that area of cold weather. This being said, unless we suddenly enter the start of a new ice age all across Canada, these sporadic cold spells are unfortunately not enough to rid us of this continually spreading plague of destruction. Yes, there are action plans prepared and in place and yes, the Canadian Ministry of Forests and Range are really trying to get to grips with finding a solution to this costly problem but to date, the efforts and methodology being used has had little or no effect on the overall problem.
The good news is that an answer to this massive problem does exist and better still, it is an answer, which consists of no chemicals, no toxins, no poisons and no danger to either the forest or to the people who would apply the solution. This answer can be found right now in the form of a golden all natural organic fluid formulated around a cedar oil base. This fluid can totally eradicate the pine beetle and a few other nasty insects at the same time. It is not cheap but then again it is not as expensive as some of the other treatment that have been tried. It is non hazardous and will not harm the environment in any way and it is here and available right now. Unfortunately, for now it appears that here it must stay as the Ministry of Forests and Range are continuing their quest with what they feel they know best. Maybe someday, hopefully soon, they will realize that we can defeat this natural pest by using a totally natural substance.
