Explanation:
The rapid rise in human population and the corresponding demand for resources have had a dramatic impact on the natural world. While global warming, acid rain, and holes in the ozone layer affect the whole planet, other changes, such as habitat destruction and hunting, threaten individual species. Over millions of years, many species have adapted to natural changes, such as long-term variation in climate. However, it is more difficult to living things to adapt to the harmful materials released into the environment as a result of human activities.
Wild plants and animals live in a particular set of surroundings, called their habitat. Nowadays people are in a hurry to change habitats to suit their own needs - to create farmlands or build cities, for example. The way people live threatens the delicate balance between living things and their habitats.
A quarter of all the plants in the world are known to be in a danger or threatened with extinction.
The world has over nine million square km. of forests. This is a lot of trees and also a lot of different species of trees. But they are disappearing fast. Every day we use paper and cardboard, both made from wood. We use different kinds of wood in furniture and in other ways. Every year over 100000 sq. km. of forests are cleared for different uses, and a lot of forests are so badly damaged that they will hardly be able to recover. If we go on like this, by the time you are as old as your grandparents are now all the forests on earth can be destroyed. This includes rainforests in South America, Africa and Asia. The huge forests help to control the world's weather, and to produce much of the oxygen in the air. There are many illnesses which we still cannot cure. There are old ones like cancer and new ones like AIDS. It may be that the medicines we need will be discovered in wild plants in savannas, deserts or rainforests. If we destroy these places, we will never find the cure.
A lot of endangered species - fish, reptiles, insects, birds, mammals - are disappearing fast. By the year 2030, scientists report that 25% of all animals, birds and insects may be extinct. The reason is Man that kills animals and destroys their habitats.
