There are massive swaths of land in the lower 48 that are pretty much untouched beyond a few footpaths that are rarely used.

The best one can do is 21 miles from a road - in Yellowstone

A forestry or old logging road that hasn’t been used in 50 years doesn’t come to mind.
Virtually no forest service roads are older than 50 years old, as most were constructed after WW2 to assist in logging.
You’re splitting hairs.
The entire country has been surveyed, so of course it's been touched (as defined by some human presence at some point in time).

Others ways, like reducing each individual’s carbon footprint or clean energy just gives us excuse to breed more and overwhelm the planet, but later.
The poorest 50% of the world would absolutely love to emit more CO2, and will do so just as fast as they can acquire the resources.
I don't think any steps to limit population growth really need to be taken, however, other than two things which are good in and of themselves: women's education, and improving access to birth control.
But concerns about Earth's carrying capacity need to be taken seriously. Malthus is wrong right up until he isn't, and we should strive to avoid hitting that limit.
It would be cool if we could keep the population of the globe like 1/10 what it is now but I don't know of a humane and rights respecting way to achieve that.
Or maybe if we reduce our standard of living it would help but how low can we go? And people aren't going to go for that either. It's a tough problem.
