// The Power is Yours by Christian Martin 
//  Click on all of the moving forest before there aren't any left we want 
// to increase the size of our rainforests and thats what I have done here
// This code now not only allows the pictures to move around the screen and 
// Clickable to make them huge but now you also get to see different backgrounds
// by moving the mouse.
// this is pretty much a blatant eco terroist game inspired by Captain Planet
