Question

why is methane a concern in agriculture? it affects the atmosphere, which negatively affects agriculture. it promotes crop growth, increasing agriculture yields. it increases cattle populations, which positively affects agriculture. it controls insect pests, increasing agriculture yields.

Explanation:

Methane is a greenhouse gas. When it accumulates in the atmosphere, it contributes to climate change (e.g., global warming). Climate change can cause issues like altered precipitation patterns, extreme weather events, and temperature changes that harm agricultural systems (e.g., crop failures, disrupted livestock conditions). The other options are incorrect: methane does not promote crop growth, increase cattle populations, or control insect pests in a way that benefits agriculture; in fact, its atmospheric impacts are largely negative for agriculture.

Answer:

It affects the atmosphere, which negatively affects agriculture.
