Question

Which sustainable practice is paired correctly with its impact on the environment?
Using bamboo results in an increased use of forest trees.
Practicing contour plowing results in a need for more land.
Setting irrigation systems to run longer results in a reduction of water use.
Building more wind farms results in a reduction of fossil fuel use.

Answer 1

Building more wind farms results in a reduction of fossil fuel use.

Explanation: Wind power generates electricity without burning fossil fuels, so adding wind capacity displaces fossil-fuel generation and lowers fuel consumption and greenhouse gas emissions (assuming it replaces fossil-based electricity).
