Question

which statement best exemplifies the concept of sustainability?

water extracted from underground resources must be equal to or less than the water that recharges the underground resources.

forests that we have today will be preserved and not used for human consumption.

the environmental protection agency sets stricter standards on air pollutants, such as sulfur dioxide and nitrogen oxides.

human population must decline for the foreseeable future to maintain earths natural resources.

Explanation:

Sustainability focuses on using resources at a rate that allows them to replenish, ensuring availability for future generations. The first option directly reflects this balance (extraction ≤ recharge), while the second (no use) is extreme, the third (regulations) is a policy tool not the core concept, and the fourth (population decline) is an unnecessary extreme measure rather than the definition of sustainability.

Answer:

Water extracted from underground resources must be equal to or less than the water that recharges the underground resources.
