I think the word crisis was as applicable in the seventies as it is today. In the Big Picture, we do not have a lot of time to fart around. Thirty years is nothing in the Big Picture.
I do not recall talk of a global cooling "crisis" back then. Nothing whatsoever on the scale of the warming trend that actually has been chronicled since at least the early 1900's. There was a very brief period in the '70's when temps overall dipped a bit, but that lasted but a short time and then it was back to generally climbing temps once again. The cooling debate never went beyond but a few advocates of a school of thought that temps were going to be in decline for an extended period of time.
It is likely true that about 1/3 of the available resources initially presumed to be available as industrialization dawned are gone, at least temporarily. Not just trees, but all of those resources. That's one reason why there is talk of mining on other planets. Sometimes, new repositories of certain resources are discovered on earth, thus the numbers are always in flux to one degree or another.
There is some tree replanting that provides for the continuation of the ability to harvest from those particular areas, but not nearly enough to offset the overall loss of timber worldwide. The United States has most certainly lost a huge hunk of its woodlands.
