False Sense of Eco-Satisfaction

There are heaps of “environmentally friendly” or “eco-friendly” products/services in the market. However, using these kinds of products/services doesn’t mean that we are doing something good to our environment. One most common example is the use of biodegradable plastic bags.

Recently, I had an interesting discussion with a man in a liquor store about plastic bag alternative. The liquor man is quite conscious about environmental issues and he is already using different alternative to reduce his business’s plastic bag consumption. He chooses to use bio-degradable plastic bags as alternative as he thought other alternative such as paper or cardboard need to chop a lot of trees and it is not good to our environment, while bio-degradable is made from starch and other degradable material which won’t harm our environmental like normal plastic bags. He wants the Australian government to substitute billions of shopping bags with biodegradable bags to solve the environmental problems created by plastic bags.

To certain extent, he is correct. But there are still lots of issues related to biodegradable bags. First of all, many of them are not 100% degradable. Than, what kind of chemicals they release when they break down in water, sun and in landfill is still uncertain, and the leftover pieces could be just as harmful as normal plastic bags. There is also an issue of the short term harmful effect to wildlife: until biodegradable products actually break down they still pose the same danger as non-biodegradable plastic bags. What more important is using biodegradable shopping bags may promote littering as people think the bags will break down in the environment no matter how they are disposed of.

Having such false sense of eco-satisfaction is very dangerous as people are not able to recognize what is being wrong and fail to figure out further improvement. The other similar example is the use of green energy. Shifting to renewable energy is good to our environment but if our energy consumption behaviors do not change, our environment won’t be benefited too much by the shift. The root cause of most of environmental problems is all about our consumptive life style.

“Doing good to environment” and “doing less harm to our environment” are fundamentally different. People should not mix these two things together or our environmental progress will remain no change or even stepping backward. Indeed, we should do both things together. We also need to be more conscious about how “green” of those "environmentally friendly" products/services are as well as being more critical about how “green” of our consumption pattern of using these kinds of products/services.

Surely bio-degradable products, defined as degrading to water, carbon dioxide and "non-harmful" other residues within six months by the European Union increase the rate of production of carbon dioxide.

On the other hand a non bio-gradable product which lasted say ten years before it produced the above products would introduce carbon dioxide much more slowly as well as having the possibility of RE-USE. Which is very different from recycling.

Building wooden houses which might last 100 years or more before re-assembling some of the structure in a new one rather than brick or other silica derived materials requiring high energy inputs, concrete or plastics would be good.
