Inaction will lead to climate change killing millions of humans. If someone won't consider eating vegetarian more often, switching to chicken is far better from an ethical standpoint than doing nothing.

People killed by climate change 250,000/year

Assuming switching to chicken reduces carbon by 12%, assuming carbon responsible for 250,000 death then meat consumption is responsible 30,000 ppl/year

Number of cows in u.s. 30,000,000 for 3% of global market

US market responsible for 900 deaths / year 140 chickens / cow(calorie wise)

estimated 20 years of life lost per death

18,000 QALY for 4.1 billion more chickens

Rough estimate of 2.3 minutes of human life gained per chicken raised

Thanks for doing that calculation. I really appreciate that you put in that much work.

> People killed by climate change 250,000/year

Is that a current number? Or a projection of what might happen with 2 degree or 4 degree Celsius increase in temperature?
