The ugly truth:

  • Meat and dairy provide us with just 18% of all the calories we consume and 37% of protein, it uses  83% of farmland and produces 60% of agriculture‚Äôs greenhouse gas emissions.
  • Over double the population of the United States could be feed with the produce grown for its livestock.
  • The seven billion livestock in the United States consume five times as much grain as its entire population.
  • Farmland, an area equivalent to the US, Australia, European Union, and China combined, could be reduced by more than 75% and we could still feed the world with the elimination of the mass production of meat.

Not all meat is created equal:

  • beef cattle raised on deforested land results in the emission of twelve times more greenhouse gases and uses fifty times more land than beef cattle raised rich natural pastures.
  • The lowest impact beef is responsible for six times more greenhouse gases and thirty-six times more land than any crop grown for human consumption.
  • Over 80% of the deforestation across the Amazon rainforest is linked to cattle ranching.
  • Cattle are estimated to generate 20% of overall U.S. methane emissions.
  • Beef results in up to 105 kilograms of greenhouse gases per 100 grams of meat, while tofu (soybean curd), for example, produces less than 3.5 kilograms of greenhouse gases per 100 grams.


  • Between the years 1971 and 2010, the production of meat has tripled from 200 billion pounds to 600 billion pounds while the global population only grew by 81%.
  • Each generation is consuming more meat than the last. At this rate, meat production will double by 2050 to about 1.2 trillion pounds a year, putting further pressure on the health of our planet.

    I love the interactive aspect of your project! While it is sometimes seen as a negative thing, comparison to other people can sometimes help to motivate. I am pescatarian, but I am interested with having an even stricter diet. You’re statistics make me want that even more. I hope people engage with this project because I think it is a huge and underrated part of mitigating climate change.

    This is a really cool project! I am vegan and have appreciated it for the good things it does for me, animals, and the environment. Thanks for giving me some good facts I can share with others who wonder why I eat this way!

      There are so many reasons as to why people should go vegan. I wanted to shed light on another (less known) reason to eat less meat!

    Hey Luis!
    I love the concept of your project, and I agree with all of the points you put forward, so thank you for that! I also like the fact that your presentation is easy and fun to follow.
    I was just wondering, would vegetarianism be a better switch than veganism? Because I feel like it would be easier for people to accommodate, and it might have an impact that is as good as the one veganism could have.

      Any change is better than no change! While veganism would be ideal vegetarianism is great as well. In fact, everyone doesn’t need to stop consuming meat for the rest of their lives. They just need to reduce their intake significantly.

    Hey Luis! Thank you for raising awareness for this very important issue. I have never really been aware of the amount of meat I consume or the effect that it could have global warming, but know I know to watch myself and try to aim for a primarily vegetarian diet. Have you thought about what other steps we can take to convince more people to stop eating so much meat?
