@ijesuschrist, Green Peace takes environmentalism very seriously, and they have to in order to make the desired impact. Most people do not really give it a thought, but humanity is better off finding a way to be more sustainable with the planet.
Green Peace offers a lot of good information on lifestyle changes that have both health and ecologically sustainable benefits. One of the best ideas they have is they have a list of environmentally irresponsible companies and ask their followers to boycott them until they change their practices.
I believe this idea should be expanded to not only environmental issues but social issues also, and that mainstream media or government should implement it on the broad scale. The only problem with it is it can be abused for corruption; a company may offer bribes to keep their name off the list, and some companies may use it to destroy competitors, but otherwise if it is independently monitored and peer reviewed, it is a great idea.
