Why are there increasing efforts to reclaim wastewater? A because wastewater can be used to fill lakes and streams that are drying up B because wastewater can be used to recharge underground drinking water sources C because many areas are experiencing higher than average levels of rainfall throughout the year D because the localized demands of the growing human population exceed the amount of fresh water that is available

The answer is: because the localized demands of the growing human population exceed the amount of fresh water that is available.

Explanation:

"Water reclamation" refers to treating wastewater through several steps in order for it to be reused. This is seen as one of the strategies which can be used for the future generations when it comes to saving water.

According to the World Health Organization, reclamation of water is essential in order to address the increasing levels of water scarcity in the world due to population increase. In order to do this, reusing wastewater or discharging it back to nature will be able to save the freshwater supply and prevent its depletion.
