Answer:
C. Decrease your consumption of beef.
Step-by-step explanation:
The production of beef needs lots of land, which leads to trees being cut down, releasing carbon dioxide. Also, the ruminant animals used to produce beef end up farting a lot from their diets, and these farts are of high metane, which leads to greenhouse gases being emitted in the athmosphere.
Common plant proteins, otherwise, produce way less of these gases.
So the correct answer is:
C. Decrease your consumption of beef.
