Question 15
Explain how the supply-demand reversal of environmental resources account for the current environmental crisis.
View answer
Earlier the demand for natural resources and services was far less than its supply
As a result, environment was able to easily regenerate the resources
Pollution was within the absorptive capacity of the environment
So, there was no environmental crisis
But now, the demand for natural resources and services is far greater than its supply
As a result environment is not able to regenerate the resources in the same time
So, we have to deal with environmental crisis
Thus, a supply-demand reversal has accounted for current environmental crisis
