We in the world are using up our natural resourses and soon our children,will have no playgrounds,no forest paths,mountain trails to hike in or ride on,no rain forests to see or oceans to swim in.Polotion and garbage will replace it all.We will not be able to breathe fresh air.We will not see a blue sky and white clouds.Global warming also will be a huge factor.More hurracanes and floods,erosion of land and melting of iceburgs and glaciers.We are already losing our animals and soon if we are lucky will still see them in zoo's but not in the wild!
