We love sea; we often use sea like place of recreation. But... we usually don't think about pollution of the sea. Once upon a time there were green forests, covering our planet everywhere; there were clean water, fresh air. But then people came here. For all their long history they were fond of fighting. Till overlays they like to speak about their fame bought by blood. They never thought about nature. We are speaking about violence. Isn't it violence? We are consumers; we can only use our Earth... Here you can see what people usually give back to nature, traces of wars, and militarism of our countries.
