Except in the US National Park Service, where the rangers and ecologists, etc. were among the first to speak out, and haven't stopped. People working in conservation (and adjacent professions) have to fight everyday to protect things.
The US has proven to capitalists that if they can ignore and outlast the initial groundswell of outrage, the population will eventually normalize and accept anything. Everything from school shootings to literal Nazis in the streets has not resulted in a sustained campaign of resistance.
