The environment and the ecosystem.

The Environment refers to the air, water, and land in which people, animals, and plants live. So human beings, animals, plants, air, water, and soil are the main elements of the environment. The natural forces such as storms, cyclones, and earthquakes are also a part of this environment. Climate is thus a condition of the environment.

All things that make up the environment are interrelated. The way in which people, animals, and plants are related to each other and to their surroundings is known as ecology. The ecosystem is a complex web that links animals, plants and every other life form in the biosphere. All these things hang together. The system is in a steady state of dynamic balance which means that by altering any one part of the web you can affect all the other parts. For example, the destruction of forests may have serious ecological consequences on humans and animals.

It is the responsibility of human beings to prevent the environment from being spoilt. To make life healthy and comfortable we should keep the environment clean and danger-free. But often people spoil the environment by doing unwise things and, as a result, endanger their own lives. It is the ecological imbalance that causes changes in the world's climate and brings about different kinds of natural disasters.
