"all that kenetic energy released when jumping off a building was formerly potential energy stored when walking up the stairs. How can that lead to life destroying conditions when life previously held that energy?"

The rapid change in environments can make many species no longer suitable for their environment leading to extinction. Sometimes they can transfer to a new environment, or sustain at a degraded efficiency, but often they cannot if the environment change is drastic enough. This is happening everywhere all at once.
