How do erosion, desertification, deforestation, and damming impact the environment? a. they negatively impact the environment by limiting greenhouse gas emissions. b. they positively affect the environment by creating more places for humans to live. c. they positively affect the environment by protecting biodiversity and animal habitats. d. they negatively impact the environment by destroying soil, animal habitats, and waterways.

The correct answer is - D. They negatively impact the environment by destroying soil, animal habitats, and waterways.

The erosion, desertification, deforestation, and damming, all have very negative impacts on the environment, and unfortunately, they are almost exclusively caused by the human activity, even though they can appear naturally as well.

The erosion, desertification, and deforestation are resulting in destruction of the soil layers, as well as causing multiple hazards. Also the animal and plant habitats are heavily affected as they are pretty much destroyed. The damming is contributing to restricted movement of the water, changes in its temperature, and changes in the habitat, and that affects the biodiversity very badly.
