Humans have transformed the environment, and the environment has affected human events. Human beings live on earth together with countless kinds of animals and plants, and all human activities have impact on the environment, affecting the earth and determining the fate of all living things, of course human ourselves. People have transformed the environment, for instance, the greenhouse effect and the resulting global warming and air pollution. According to NOAA's global climate summary for 2018, average temperature has increased by 0.07C every 10 years, no matter on land or in the ocean, since 1880. This is caused by the greenhouse effect, which is mainly caused by the human activity including excessive burning of coal, oil and natural gas from modern industrial societies, and the emission of carbon dioxide gas from automobile exhaust into the atmosphere. The environment has also affected human events in many aspects. Air pollutants produced by exhaust emission can harm people’s lungs, to the end maybe a cancer. Rising temperature will cause melting of the polar ice caps, and then sea levels will rise, which will affect residents of coastal countries. With colder winters and hotter summers, the laws of agricultural production will be disrupted. That will also lead to the extinction of species and the disorder of the biological chain, so that the destruction of the ecosystem, ultimately has a great impact on human life.
