When I am think about future of our Earth. I really scared about every life who live in our Earth,started 1900 we learn to use earth power and elements for human progress.in 1940 human destroy earth 40% by use elements for name of science and progress for humanity but we we're not think about nature life and resources for it we are only use nature's life.now we are on 21th century and our science say that the ice of antarctic are converted in water and one day ice age of Antarctica are gone and big cities of human were destroyed by water so why are we still snach earth like money. Why our society not try to understand that our Earth will destroy by us then where will we go for breathing and food so keep thinking about future of our Earth ??.
