So for example there are more trees in N America today than in the 1800’s because we are no longer cutting them down for heat and railroad tracks.
What unreceivedogma comes back with:
a pdf about forested area and, "the quality of today’s lumber is significantly inferior to that of 100 years ago."
The assertion there are more trees is met with forest lands and lumber quality. As if these are anywhere near the same- or even remotely related to each other!
This is why no, I will not have to back up anything with a citation. Why would I? You would just shift the target yet again. There is no point- at least not until you learn to discern what the point being made even is!
