What will happen if we go on cutting trees?

• Deforestation is the systematic removal of a lot of trees at once. The most significant direct impact of deforestation on biodiversity is the environment as a whole.
• Animals who dwell in trees are forced to leave their homes and find new ones. The creatures became extinct as a result of this. Deforestation also has an impact on the water cycle, which causes a drop in local rainfall and adverse effects on a variety of aquatic creatures.
• Cutting down trees increases the likelihood of natural disasters like floods during periods of heavy rain. 
• They can also increase the likelihood of soil erosion because trees have a high rate of water transpiration and bind soil to slopes with their roots, which slows erosion.
• The trees have a role in both the bioremediation process that lowers the rate of pollution brought on by several toxic gases as well as the production of oxygen.

Hence, option C is the correct answer.
