deforestation the chopping down of large numbers trees for human use is considered to have a negative impact on climate change.
Rudiy27

Answer:

Plants take in carbon dioxide from the environment for photosynthesis. Because trees are large, they need a lot of energy, which likely results in a lot of carbon dioxide being removed from the air. If they’re chopped down, there will be fewer trees to remove the extra carbon dioxide from the air.
