The environment is the natural world in which people , animals and plants live. The natural environment has been seriously affected and degraded by human activities through many decades. For instance, the burning of fossil fuels by factories and motor vehicles has led to air pollution and resulted in acid rains, greenhouse effect and global warming. The use of harmful chemicals in agriculture has led to serious soil pollution and health problems. Deforestation for land use has affected the ecosystem and led to the extinction of rare animals, and extreme floods and land erosion. Harmful rubbish and sewage dumped in rivers and oceans has polluted the water and harmed aquatic animals. There are many human activities having serious impacts on the natural environment. They have changed and degraded the natural environment and led to various health problems.
We should do something immediately to protect our environment . For instance, we should control the burning of fossil fuels and encourage forestation to replace deforestation. In addition, there should be appropriate places to dump harmful rubbish and chemicals to reduce the rate of water pollution, a threat to human health and a danger to aquatic animals.
To minimize the rate of environmental degradation and to raise awareness of its threats, The preservation of the environment should be included in education and mass media. People should make every effort to preserve the environment for the next generation.
