Oh Canada

16 02 2009

Obama is coming to Canada this Thursday to discuss how to combat global warming, greenhouse gas emissions and the oil sands of Alberta.

Oil sands are areas of land with deposits of Bitumen, a crude oil in the form of sand. The result is a fossil fuel that is very hard to refine, but produces a lot of energy.

Some Canadian lobbyists feel Obama’s visit is their chance to debate new pollution caps for refining the oil sands. The sands produce oil that has three times the carbon impact per barrel in the production process as regular oil.





Plastic Bags From Corn

Plastic grocery bags that are 100 percent biodegradable exist, so why aren’t they used in stores? Some American stores like City Market use these bags, but why aren’t more?

The brand of plastic bags called BioBags uses a bio-polymer instead of polyethylene to make plastic. Essentially, this means the bags are made from corn.

These two articles, one from India and one from Guam show that the U.S. is far behind in utilizing biodegradable technology. One debate, which recently took place in Virgina, was over bills that proposed the banning of thin plastic bags in favor of thicker bags with durable handles to encourage re-use. The bills were denied by both the state House and Senate. While I don’t think this is the way to go with plastic bags, at least the U.S. is starting to recognize the problem.
