Not at all. In many instances, these bold and inquisitive birds will actually approach people, often perching on heads, shoulders and photo equipment if their target is calm and doesn't suddenly move or make sudden noises. Their behavior can be very entertaining to watch. The main reason these birds are endangered is loss of habitat, noted above by SilverSurfer, which is a very serious issue.
That likely wouldn't do enough. Taking away everyone's air conditioning would more likely do the job, though. My family didn't have A/C in our house (near Orlando, Florida) until I was about fifteen years old. We spent summers getting wet at the local springs, a nearby swimming pool, or just sweating.
We barely survived nights because we had a whole house attic fan that was rated at about 3500 CFM.
