Humans are at risk of resource shortages. Many species are facing extinction. Nothing bad will happen to the dirt, but if 'planet' means 'biosphere' then it's at the most risk.

Unlikely Life as we know it is at risk. The planet has been through many extinctions.

The risk level is nowhere near "everything is wiped out", but the risk level for species in general is higher than the risk level for humans.

New species will arise. That's how evolution works.
