Question

Choose the correct option taking the following statements into consideration.

Assertion (A) - In 2010, the biocapacity of planet Earth exceeded by around 50%.

Reason (R) - Humans have begun to develop sustainable methods to generate resources.

• A. Both A and R are true, and R is the correct explanation of A.
• B. Both A and R are true, but R is not the correct explanation of A.
• C. A is true, but R is false.
• D. A is false, but R is true.

Answer 1

The correct option is B Both A and R are true, but R is not the correct explanation of A.

Earth's total biocapacity in 2010 was just 12 billion global hectares, which would come down to 1.7 global hectares per individual. It means that in 2010 people exceeded the biocapacity of the planet by around 50%. The situation is a risk as it exceeds Earth's regenerative capacity. The reason can be attributed to the depletion of resources due to various reasons. On the contrary, sustainable methods of generating resources are helping humans reduce the depletion of resources and develop safe ways of utilising them. For example, solar energy.
