A small reminder.
In ecology, biomass is a simple measure of how much there is of any type of living thing.
Earth contains 450 billion metric tons of plant biomass. By comparison, there's just a paltry 60 million tonnes of humans on Earth.
Humans think they own this world. But they don't.
Earth is basically a planet of plants and microbes with some fungi. Also some other stuff which probably doesn't matter very much. 
@InvaderXan 60 million tons of humans. :)
@InvaderXan according to that, there are 3.3 times more virus than humans, and 1200 times more bacteria than humans (by mass), which I find is somehow even funnier. Trees are heavy, virus and bacteria are mass-less at our scale
@a000d4f7a91939d0e71df1646d7a48 You’re so right. There are probably single varieties of bacteria which are more populous. Like, I bet there’s more lactobacillus than human on this planet!
TRASH 
@InvaderXan Marine arthropods... the lobstermass.......
@InvaderXan and this is after fishing and poisoning the oceans dead
@InvaderXan That livestock block stands out a fair bit and invites questioning, especially as it's non-overlapping with the wild mammals block..
Though both being smaller than total virus or nematode mass is some good perspective to have
