Today,I learned about which things make environment vulnerable. The reading passage tackled about the reasons on bearing pollution, which are industrialization and overpopulation. First, industrialization makes vulnerable ecosystem. Many birds and animals are threatened with extinction because of pollution and residual pesticide contamination. Next, overpopulation is one of the reasons of environmental pollution. The more people are using chemicals, the more it creates problems like; water pollution and overpopulation. To solve these problems and to protect our environment from pollution, the government should implement strict laws about limiting industrialization, and the government should encourage every family to raise only one child, like in China does.
