Sustainability

Sustainability is the existence of a process, mostly used in ecology. Sustainability is the use of eternally things or things which have an ability which allows them to refill the world by them very fast. Almost everything in the world can be apllied to sustainability. The forest is an example of a sustainable biological system. It means that there are invisible chemicals recycles like water,oxygen,carbon and more that are not a living system's but other living systems depends on it. As the human population of earth increased, natural ecosystems had changes in there balance of natural recycle and at the end it "stroke" back badly at human kind and other living systems. There are scientific evidence that sustainability can be restored but it requires a major effort from us (the human kind) and today people are so obsessed with money that by the time they will try to make a change it will be too late.
