Answer 1

The situation that is an example of a human-induced environmental change affecting a population is:

"Blue jays no longer live in a forest because the trees in the forest were cut down."

This scenario directly relates to human activities (deforestation) causing changes to the environment that result in the displacement of a species (blue jays) from its habitat.
