In animal science, “consumers” are those organisms of an ecological food chain that receive energy by consuming other organisms.
“Consumers” have important roles to play within an ecosystem such as balancing the food chain by keeping animal populations at a reasonable number by predation, for example.
In that sense, humans are not “consumers” or “predators” because they don’t keep animal populations at a reasonable number: they make them proliferate instead and destroy the planet.
Raising animals for food damages the environment more than just about anything else that we do. Whether it’s the overuse of resources, global warming, massive water or air pollution, or soil erosion, raising animals for food is wreaking havoc on the Earth.
