Which option identifies ways that people positively affect Earth’s resources?
Reika [66]

Answer:

Build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams.

Explanation:

<u>Building dams would help in generating hydroelectricity and reduce floods. Using cars that emit fewer harmful gases would help in controlling pollution and global warming. Factory waste drained into streams and rivers pollutes the water and is dangerous for aquatic plants and animals. Hence, halting the runoff of factory waste into rivers and streams would save water pollution. Halting the use of resources is impractical. Increasing the mining efforts would lead to further depletion of resources. Hence, the correct options are: build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams which would positively affect Earth's resources</u>
