(The earth is groaning) Let’s briefly talk about where the harm caused by humans to the earth is manifested.

Any human activity on the earth will bring some damage to the ecological environment of the earth, but only to varying degrees. For example, the most primitive farming methods of primitive people and their production and lifestyle also cause damage to the earth's ecological environment. The ecological environment has caused some damage, such as hunting, burning, etc. Because of limited technology and little demand for nature, the damage was not severe. Later, there were many wars in human history, especially the emergence of firearms, which introduced wars to the ecological environment. The damage to the environment is even more significant. The use of various new weapons in the First and Second World Wars caused damage to the earth in many aspects, including biological damage, vegetation and atmosphere. In modern times, we have no understanding of outer space. All exploration activities will put a huge load on the earth's atmosphere and destroy the ozone layer. Our dependence on fossil resources has also increased the emission of greenhouse gases. The construction of various facilities has also cut down a large number of trees and vegetation, causing serious damage. , the sewage discharged by industries has brought pollution to the earth's water bodies. In short, the advancement of science and technology has also increased the harm of human activities to the earth.
