The use of preservative wood reduces the greenhouse effect?


The raw material of preservative wood-the forest converts carbon dioxide and water into biomass and releases oxygen during photosynthesis, so it can absorb a large amount of carbon dioxide. This effect is called the "carbon sequestration effect" of forests. It is estimated that the production of It biomass needs to absorb 1.6t of carbon dioxide and release 1.2t of oxygen. Through the carbon sequestration effect of forests, the greenhouse effect can be mitigated. However, while the forest performs photo-mediated effects, the forest also undergoes respiration to consume part of the biomass and release a certain amount of carbon dioxide.




In the process of human burning of fossil energy such as petroleum and coal, a large amount of greenhouse gases, including carbon dioxide, methane and nitrogen dioxide, are produced, which keeps the earth warming. This will force human beings and all living things to face a new environmental condition, and under this new environmental condition, whether human beings and other living things will survive or how will they survive. This will be a huge challenge. The increasing trend of the concentration of carbon dioxide in the atmosphere is very rapid, and the speed does not remain constant, but shows a gradual increase trend.
