Question

What is the main reason why raising cattle contributes to
global warming? (1 point)
Cattle release carbon dioxide as they breathe, similar
to humans.
Cattle eat grass, which reduces the amount of plants
that remove atmospheric carbon dioxide.
Cattle have microbes in their stomach that produce
methane during digestion.
Cattle store nitrogen, which is released as nitrous
oxide as they die.

Answer 1

The main reason why raising cattle contributes to global warming is that **cattle have microbes in their stomach that produce methane during digestion.** Methane is a potent greenhouse gas that has a much higher heat-trapping ability than carbon dioxide.
