In the question given below there are 2 statements marked as Assertion (A) and Reason (R). Choose the correct alternative from the following options.

Assertion (A)- We are today almost at the threshold of environmental crisis.

Reason (R)- The demand from environment is beyond its carrying capacity and wastes generated are beyond the absorptive capacity.

Both (A) and (R) are true and (R) is the correct explanation.

When the resource extraction is more than the rate of resource regeneration, we say the demand from environment is beyond its carrying capacity. And absorptive capacity refers to the ability of environment to absorb degradation. The waste generated should be within the assimilating capacity of the environment.

Since, the demand from environment is beyond its carrying capacity and wastes generated are beyond the absorptive capacity. We can conclude that we are almost at the verge of environmental crisis.
