Consider statements about environment: 1. Deforestation causes soil erosion. 2. Afforestation helps reduce global warming. 3. Plastic is non-biodegradable. Which are correct? MCQ with Answer and Explanation

Deforestation, the large-scale removal of trees and vegetation, exposes the topsoil to wind and water, leading to severe soil erosion and loss of fertility. Afforestation, the planting of trees in barren areas, increases biomass and helps mitigate global warming by sequestering atmospheric carbon dioxide through photosynthesis. Most plastics are synthetic polymers that are non-biodegradable, meaning they cannot be broken down by natural biological processes and persist in the environment for centuries, causing pollution. All statements are correct.
