Do You Know Environment?
The world today is economically richer and environmentally poorer than ever.

1. Ernst Haeckel was a supporter of Charles Darwin. His idea of ecology was forgotten until about 1900 when biologists began to take serious interest in it.
2. Ecosystems are distributed over the Earth mainly according to climate. There are zones of different climates ranging from cold and dry at the poles, to hot and wet at the Equator.
3. Some ecosystems have distinct boundaries. They can be easily differentiated. But many ecosystem merge together. The area where they merge is called an ecosystem.
4. Human beings can also change their environment to suit their way life. The study of humans change their environment is known as human ecology.
