To be honest I feel the same way. No green = no good

there are some evil places with trees, for example Taur-nu-Fuin, "Forest under Night," the pine forest south of Morgoth's mountain fortress Thangorodrim. or Mirkwood, especially southern Mirkwood near Sauron's fortress Dol Guldur. or the Old Forest east of the Shire, which isn't evil exactly, but unfriendly at least

Most of space is therefore evil, except the ENTerprise

This goes back to his time on the western front. No trees along the whole thing

No Man's Land was certainly the result of evil, and I've never seen a living, growing tree in any picture I've ever seen

I don't blame him. Shade and shelter from the rain and a nice place to lean. Sometimes food and their cast offs can make a bit better shelter.

Two of the American colonial exports that established a foothold in North America were potash and lumber.

Most places under the "spell" of Sauron are south and east. It's a European trope, I wonder why...
