Greenpeace

There is this beautiful park beside my house hundreds of people go to, and if i could have some help on how to get petitions, contact government try to get petitions etc... I just think that it would be a great event. People would come, fun, etc... maybe a few bands, etc... but I don't know how to go about it I want to raise conciousness. And for people to donate money. I can't belive that the polar bears are expected to be exctinct in 1212. That's unreal.. I want to help. I just need more info. I 've never done this before. Thanks
