Nonhuman Animals: Farmed, Wild, and Future Animals

Humans comprise just 0.01% of Earth’s biomass, and an even smaller percentage of all living individual animals. More farmed animals are slaughtered for food each year than the number of humans who have ever lived in all of history and most of them will live their entire lives in factory farm conditions. And at any given time, more than 99.9% of the animals alive are invertebrates, which face complex and varied harms in the wild.

Questions to consider

  • What are the comparative moral weights of different species?
  • How should we prioritize the welfare of farmed animals, wild animals, and animals in the far future?
  • What tactics are effective at improving animal welfare?
