Are humans a keystone species?
According to Paine a keystone species is a species that plays a large role
in the community and ecosystem if removed from the planet the effect would
be big; if humans were to be removed from earth I feel the conditions in
the enviorment would improve. With humans roaming the earth the enviorment
suffers because of pollution and the killing of animal habitats. Everyday
many rainforest are cut down leaving animals to abandon their habitats
therefore they have nowhere to live and many animals lose there lives in
the process. Without the humans on the earth animals would live a better
lifestyle. Without humans on the earth there would never had been a issue
involving the ozone layer beacause pollution would not be a issue.
Therefore this makes humans a keystone species because with humans on the
earth it hurts the enviornment rather than helping the enviornment. The
effect of the humans being eliminated from the earth would play a big role
in the ecosystem.
It is true that a keystone species would affect a whole community if taken out of the map, but i do believe that humans are not keystone due to the fact as you said, we affect the environment, we do not improve it at all. If we are taken out, as you said the world will become a better world for many other species, that means that we have absolutely no effect on communities overall.
