just base on my opinion,
people don't learn to recycle,
gas, plastic, heavy metal, and paper are wildly use and that hurt the environment.
rice people care only about NOW not the future so they don't plan on saving resources for next next next generations.
poor people can never afford to change what they are using, and recycling campaign needs a lot of money and labor to be successful so third world control can only keep on accepting atomic waste and never learn the bad part of nuclear pollution and how to recycle well
does it sound enough? if no e-mail me at the SN @ yahoo.com la
