Answer:
Negative effects of deforestation on the environment are erosion, mass wasting, loss of biodiversity, destruction of ecosystems, climate changes, etc.
Explanation:
Deforestation is one of the major environmental problems. It is not a problem that has occurred recently but has systematically been going on for several thousands of years, but has been becoming a bigger and bigger problem with the growth of the human population. There are many environmental problems that occur because of deforestation, such as erosion, mass wasting, loss of biodiversity, destruction of ecosystems, and climate change.
When the vegetation is stripped from some area, the soil gets exposed much more, so it gets eroded by much higher rates, leading to loss of fertile soil. The soil also losses its stability, so when there are higher amounts of rainfall or earthquakes, there is a high risk of mass wasting. By destroying the vegetation, a lot of organisms lose their habitat, thus they die out or get dangerously close to extinction. Having less vegetation leads to higher temperatures of the soil and the air above it, stronger winds, and a decrease in precipitation, all in all leading to change in the climate on a micro or macro level.
