A researcher is studying the impact of different community activities on natural resources. Which activity is correctly paired with the level of impact it has on natural resources?
little impact when humans exclusively use fossil fuels for power needs
great impact when humans use alternative water sources for nondrinking functions
little impact when humans plant different types of trees for different uses
great impact when humans maintain a diverse diet that includes various protein sources

great impact when humans use alternative water sources for nondrinking functions

Explanation:

Water is one of the most important natural resources. Water is life and although it has a large volume on Earth, access to potable water is quite difficult especially in Third World countries. Water is very essential for every living organism.

This explains why there will be a great impact when humans use alternative water sources for nondrinking functions.
