How is veganism is better for the planet?
In: 3
I don’t know if this fully plays out, but one of the reoccurring arguments is based on how much water, feed, and land is needed for say the beef, pork, or chicken industry. There’s also issues regarding animal waste and sheer volume of it to produce a considerable increase in methane. HOWEVER, I don’t know if there is a systematic study that covers how much harm from animal industry versus plant industry. Crops also require a lot of water and space, plus have less calories. Obviously crops are needed to feed an animal, but this is offset slightly on how young they are when slaughtered. I think chickens are 45 days old and pigs 5-6 months. You can easily feed them certain low value grains over some nutrient dense vegetables that require more. IIRC rice requires a lot of water say compared to corn/maize. At the end of the day, the tallies have to leave clean water and enough calories for humans to survive.
Supposedly cotton, vegan right?, is the biggest user of pesticides (don’t eat) and huge user of water. Does this mean leather or plastics would be better? It starts to get to all sorts of specifics that are sort of hidden/under-studied. In the end, the animal industry does cause a noticeable increase in pollution and waste while also using a lot of resources.
