People depend on the planet, on the Sun, on animals and plants around them. People must take care of the Earth. Our nature becomes worse and worse with every new day. People destroy jungle rain forests and cut down trees to make furniture. They forget that they can't live without trees and plants, because they fill the air with oxygen. We can't stay indifferent to these problems. Oxygen is necessary for our breathing.
There are a lot of special organizations which are trying to save our nature. One of them is Greenpeace. Their aim is to help wildlife to survive, to rescue animals, to save flora and fauna, which are in danger of destruction. We must find the right way to save our land, people and animals. We must take care of ecology because we are a part of it.
