Yeah that’s why they need more money to shore up those niggly holes proving that despite vast herds of grazing animals far out numbered the human population ... they held it all in for those 4000 years, and it was the lazy conservative right wing meat eating spear clinging woman bashing over the head human male population which caused all this havoc with Earth’s climate.
This will take a very sizable grant to prove, but the EPA will pick up any slack in the funding ...
