the biosphere is a meat grinder. nature is scary
The concept of nature as someone 2000 years ago might have imagined it is consigned to history. There's just spaces between towns.
Hell, I could drop you in a huge wilderness region in my state (Arizona) where you might walk a dozen miles before you encounter a "trail" (loosly defined).
Honestly, I don't know how you could end up with a take like that unless you're a European who hasn't travelled much.
