A) Clearing of forests to create crop lands
B) Extinction of certain species of plants and animals
C) Overall, continuous increase in temperatures throughout the world

Ans: B
Deforestation is the clearing of forests to create crop lands. Deforestation contributes to soil erosion, a change in climatic conditions, and air pollution. Climate changes result in increased desertification. A loss of biodiversity results in the extinction of certain species of plants and animals and thus deforestation, desertification, and reproductive changes. There has been an overall increase in temperatures throughout the world. The greenhouse effect is a contributing factor to global warming.
