Are there any laws/theoretical foundations about how diversity of species relate with total biomass on Earth?
While there is a lot of esoteric sort of talk “humanity dis-balances the live on the Earth”, I though there are formally seen hard facts (correct me if I am wrong):
biomass of human species and species we need (plants/cattle etc) is increasing;
diversity of species is decreasing
So it looks like some sort of global system change (correct me if I am wrong), but how does biology science discuss them (in case my inquiry can be anyhow scientifically formulated)?
