I'm sorry but you're just totally ignorant on what you are talking about. I recommend reading Tending the Wild by anthropologist M Kat Anderson to educate yourself.
Indigenous land management was often more intensive than what we have been doing with uncultivated lands and indigenous groups in my local area have been trying to tell people for decades that it's partially our neglect of these practices that are causing some of the problems we see today. So ironically you are the one who has not been listening.
I do too but some of it is hard to uproot. Someone has to put in the work to unravel it and it's often very difficult and unpopular work for the first experts to take that on.
