Q. Which of the following are the main harmful effects of deforestation? I. Increase in carbon dioxide concentration in atmosphere II. Loss of biodiversity due to habitat destruction III. Disturbance in hydrologic cycle IV. Desertification Which of the statements given above are correct?
A) I, II and III
B) II, III and IV
C) I, III and IV
D) I, II, III and IV
Explanation
Deforestation can be resulted into increase in carbon dioxide $(CO_{2})$ concentration in the atmosphere because trees that could hold a lot of carbon in their biomass are lost with deforestation. Deforestation also causes loss of biodiversity due to habitat destruction, disturbs hydrologic cycle, causes of soil erosion and may lead to desertification in extreme cases
