a) co₂
b) ch₄
c) cclf₃
d) o₃

summarize your key takeaways from the video.

Explanation:

MC Practice Question:

Livestock (especially cows) produce methane ($\ce{CH4}$) during digestion. Reducing meat consumption means fewer livestock, so less $\ce{CH4}$ emission. $\ce{CO2}$ is more from fossil fuels, $\ce{CCIF5}$ (likely a typo, e.g., CFCs) are from industrial sources, and $\ce{O3}$ (ozone) in troposphere is from pollution, not directly from meat production. So the gas reduced by less meat consumption is $\ce{CH4}$.

Answer:

B. $\ce{CH4}$
