You could make a hypothesis based off of past changes in ecosystems, like many say you shouldn’t overhunt based off of what happened at Yellowstone. You could also factor the current conditions of the ecosystem (ex-geography, latitude, amount of rainfall, elevation, available species etc) and figure out the conditions of which it’s running on. Ecosystems are complex bio-diverse areas and they go through countless natural and man-made changes throughout the years, but usually find ways to adapt.
