Eighth grade politics: combining the information related to the food chain, talk about the influence of human pollution and destruction on human beings themselves.

Man and nature restrict and influence each other, just like the food chain. If human beings wantonly destroy the environment, they will be punished. For example, human beings are engaged in industrial activities, and industrial wastes and fertilizers and pesticides are continuously enriched through the food chain, so that heavy metals such as mercury and chromium remain in the soil, the soil is destroyed, and the living environment of human beings is getting worse and worse, thus threatening human health. All kinds of tumor diseases and cancers are caused by human beings themselves. The exhaust gas emitted by human cars causes people to lack oxygen and so on. The deteriorating environment will overshadow our achievements in other fields. Therefore, while promoting modernization and maintaining the sustained and rapid growth of the national economy, environmental protection must be placed in a prominent position. We should realize that protecting and improving the environment is also protecting and developing productive forces.
