Design a political card, poster or cd cover

So my idea is environmentally correct and i choose to make the poster for it.
The poster it will be like someone is throwing the rubbish to the bin, on the other side will have the same person throwing the rubbish as well, but it is throwing into the world not only the bin. The world will full of rubbish and become like a black world. Then, will also need to think of a slogan for the poster and let the people to remember deeply.
this is the first idea, but seem hasn't bring up the strong message out to people, so i ask around of my friend.
