It could contribute to rising temperatures and rising sea levels.

The eastern coastal parts of United States is mostly facing a lot of problems such as the increasing temperature, soil erosion, and less amount of rainfall, due to the deforestation process and burning down of trees in order to create spaces for the cultivation of crops and also for the construction purposes.
