Since the industrial revolution, mankind has burned a large number of fossil fuels and deforested, and the emission of greenhouse gases has continued to increase, leading to a significant global warming in the 20th century
If the long-term increase in the concentration of greenhouse gases in the atmosphere is to be controlled, countries must carry out human intervention or change from Limit the use of fossil energy at the source to reduce greenhouse gas emissions; or increase the sink of greenhouse gases, that is, re-absorb the greenhouse gases emitted into the atmosphere through tree planting
If the use of fossil energy is restricted from the source, a significant global warming can be avoided
