The natural environment has been seriously affected and degraded by human activities through many decades.

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.
