Deforestation and Land Degradation Questions
What is the primary environmental benefit of urban-rural migration in India?
-
Increased deforestation
-
Reduced air pollution
-
Improved water quality
-
Increased soil erosion
B
Correct answer
Explanation
Urban-rural migration can lead to reduced air pollution in rural areas, as migrants move away from areas with high levels of air pollution.

Which human activity is a significant contributor to habitat fragmentation in tropical rainforests?
-
Renewable Energy Development
-
Sustainable Agriculture
-
Logging
-
Wildlife Conservation
C
Correct answer
Explanation
Logging, the harvesting of timber from forests, is a major contributor to habitat fragmentation in tropical rainforests, as it creates gaps in the forest canopy and disrupts the connectivity of habitats.

Which of the following is a major environmental impact of deforestation?
-
Increased biodiversity
-
Reduced soil erosion
-
Increased carbon dioxide levels
-
Improved air quality
C
Correct answer
