The only constant in the environmental history of earth is change. Glaciers, ice ages, the extinction of species, and the creation of new species. Ask one of these yahoos what changes would they accept as natural and which ones should concern us. They don’t have an answer.
Yep. As the song says, “If there’s one thing you can count on, things are gonna change.”
Liberals think that everything should be static based on the day they were born. Morons.
