Science

The genetics are incontrovertible. And we're not the first species to make life very tough for our neighbors. See the Great Oxidation Event, when some bacteria figured out how to photosynthesize, producing free oxygen. A poison to most life on earth at the time. Free oxygen also royally mucked up earth's climate, making life tough for the photosynthesizers and everyone else. The difference is, we have a brain and can chose to limit our impact. Photosynthesizing cyanobacteria did not, much like MAGAs in that regard.
