Well, 1 413 000 known species are known, with billions of each specie. So, if there is five billion of each specie, then there is 7 065 000 000 000 of every animal as a rough estimate. That plus the amount of humans-six point five billion-would make 7 065 000 650 000 as a rough estimate of all animals on the planet including humans.
