Introduction:<br>The greenhouse effect is a normal phenomenon, which refers to the mechanism that the planet's atmosphere absorbs radiation energy and causes the planet's surface to heat up (from Wikipedia). Therefore, if there are greenhouse gases, the earth's temperature will be 30 ℃ lower than it is now, making the earth unsuitable for human habitation. However, due to the development of human science and technology and resource development and other factors, the greenhouse effect on the earth will increase abnormally, When the greenhouse effect is stronger, the temperature on the earth's surface is higher, which will cause global warming. At this time, the glaciers and permafrost at the two poles will continue to decrease, resulting in sea level rise, as well as the increasingly obvious regional extreme climate, and mass extinction caused by temperature change, etc., which may affect human crops and food or residence.<br>
