Can we also say that more people would mean that more number of golf courses in the aligator habitat and hence more aligator sightings?
I'd say yes. That is a valid way to see it.
If Florida’s human population increased a lot, then
more golf courses, lawns, and houses may have been built in or near alligator habitat. So reports of alligator sightings could rise simply because there were more points of contact between humans and alligators, not necessarily because the alligator population itself increased significantly.
