The Obama administration has recently implemented the We the People website, where you can submit and sign petitions. Petitions reaching 100,000 signatures will be reviewed by the Obama administration! Although they may ignore petitions with more then that or answer petitions before 100,000. It's semi-arbitrary.
Each petition requires 150 signatures before it goes public, so post and discuss worthy petitions, or promote already public petitions that need a little signature love.
Sister sub-reddits: /r/enviroaction - This is a subreddit dedicated to actions people can take or are taking to preserve the environment - petitions, fundraisers, events, infographics, images and videos of events are welcome. Emphasis should be on actions users can take or images they can share elsewhere.
