Final answer:
Deforestation leads to less oxygen and a drier environment.
Step-by-step explanation:
The damaging effects of deforestation include less oxygen and a drier environment. When trees are cut down, there are fewer trees to release oxygen through the process of photosynthesis, leading to reduced oxygen levels. Additionally, deforestation can cause a decrease in rainfall and increased evaporation, resulting in a drier environment.
