How can local environmental changes have global effects?
Alex777 [14]

Answer:

D

Explanation:

Water and air circulate around the world in water currents and wind systems (like prevailing winds) respectively, hence distribute energy and whatever else they are carrying across the globe. This is why polluting the oceans in the equatorial region will have indirect consequences for marine life in the poles.

Pollution of air through emission  of greenhouse gases in one part of the globe will contribute to global warming across the world because these emissions will be carried around by prevailing winds and diffuse across the atmosphere.

Global warming also causes climate change that subsequently causes the displacement or migration of organisms when this change in climate is unfavorable
