What is natural anyway? Is it how a place would be if humans weren't in it? Is it how a place turns out after humans do what they do e.g. settle and rear goats?

What is natural anyway? Is it how a place would be if humans weren't in it? Is it how a place turns out after humans do what they do e.g. settle and rear goats? Or is it what humans would ideally do, but we work hard to resist because we imagine an ideal scenario e.g. desert is bad, forest is good. Shouldn't the outcomes of human uninhibited actions be natural e.g. overusing resources and pollution.
