Answer :
Answer: planting trees
Trees are very important in the fight against climate change, because they purify the air and lower the temperature of the areas where they exist.
They do this during their growth and throughout their lives, through the process of photosynthesis, in which they absorb carbon dioxide from the air (one of the main causes of the greenhouse effect) to "feed" themselves and then release oxygen.
In addition, in this process the trees help in the evaporation of water into the atmosphere, which increases the cloudiness with the consequent cooling effect on the surface.
That is why planting trees is very important, especially in the tropical areas of the Earth, because in this region the trees also allow the formation of convective clouds that help to cool the entire planet.
