Are humans a keystone species? No. Humans are not important keystone species on the earth because before humans even exist animals were living well on their own. When the humans came on the earth more animals began to die because of the living styles of humans they have to survive off killing animals and eating them. Animals are big parts of natural environment, also domesticated animals depends on humans because without humans no one is going to feed the aminals. Humans litter in the oceans and lakes that's cause the animals to get infection with bacteria. Bacteria infection causes the animals to get sick and die out so therefore not having humans might just be better for keeping animals alive. The animals and the rainforest are dying out everyday from humans cutting down trees and taking away tfrom their living habitats, causing them to be unable to get away from their predators. Therefore, humans are not a keystone species and the natural environment might just be better without humans.
