If beavers invented a lifestyle that enabled them to live at densities up to thousands per square mile they'd compromise a hell of a lot of biomass too.
The fact that there's more humans doesn't imply anything about the other animal population (though I suspect that it's not good for the other animals though).
b)There are about 50 people per square kilometer of land. Even adjusted for farmland humans are still gonna blow every other large predator out of the water. Even if you include commercial fisheries that still blows every other large predator out of the water. Maybe there's a couple seasonal localized concentrations of certain predators that are higher but nothing else comes close to that number.

I worry quite a bit about the habitat distruction necessary to comfortably sustain 7–10 B people, but the comparisons to a virus and the implied moral judgment have always seemed off-base. Nature doesn't care if we destroy everything. I care.
