Dear editor,

The first problem is the rise in population. The population is increasing so sharply that there aren't many more resources to use. Because of the large population, a large number of natural resources are overdeveloped. Overdevelopment of natural resources has a negative effect on the environment. And then, cutting down trees from forests is a kind of overdevelopment of natural resources. The trees which are cut down are usually used to make paper or furniture.
What's more, the lack of water resources is always an important problem for some countries. In those countries, many people don't have access to safe drinking water. So many countries are suffering from a lack of water resources. The last one is air pollution. The polluted gas mainly comes from factories and dwellings.
To solve these problems, we must start to protect the environment, such as reducing the waste of natural resources or throwing rubbish into the litter bins. I believe if we do all these well, the environment will be better.
