Probably Mesa Verdians understood if you cut down trees around your village, your quality of life will go down.
- ncmncm 6y agoPetra, in Jordan, is said to have once been surrounded by forest. When you cut down all the trees, in many places, you get desert where the trees used to be. I.e., trees bring and retain moisture. It can work in reverse: growing trees, you can encroach on desert. This is going on today along the southern edge of the Sahara. (BTW, not "Sahara Desert"; Sahara means desert.)
