If the space on earth,water and 'all of earthly resources' were divided 'equally' between ALL living species...how many human beings should be living

 One idea I spend fantasizing and thinking about is this

Imagine that all the resources of the world were divided (with equity and not equality) between ALL the living species...animals, birds, insects, reptiles, germs, fish, plants, trees, ferns, algae, etc, then how many human beings would be on earth? a million? or lesser? How many of each different race?

on Asia, how many trees, plants, animals, people, algae, etc of that region?

The same for all other continents.

This would lead to fairness for all living species, safety of the environment, and a vast reduction of human beings, non-destruction and in fact thriving of all species. 

I thought of this when I read about deer being killed and hunted as they are 'too many'. wild pigs being killed as their numbers have increased and they are destroying the environment. 

What about people? people increasing in numbers. people destroying environment.  people taking away space from other species
