Without some keystone species, entire ecosystems could fall apart :c
Like the ordeal with sea otters off of the west coast of the US.
Fewer sea otters > More kelp > overgrowth of kelp > taking nutrients from other species > other species in turn go extinct > etc.

Ecosystems are way too fragile in all honesty, it's remarkable that life has progressed so far I think. And concerning that, Pandas die > bamboo overpopulation > fewer nutrients for other plants > fewer resources for other animals > etc. Basically any organism's extinction can upset everything in an ecosystem, I'm not sure I'm getting exactly where you're coming from with this one...
