be a hunter gatherer... only way to save the Earth?

I’m starting to get close to my 43 things limit for goals. Since this is very similar, if not the same thing for me, as making a smaller egological footprint, I will focus on that goal, instead of doing both.

this is mostly the same as my goal, make a smaller ecological footprint. However, I figure that people can always do more things and have more goals when it comes to the environment.
