Please don't be offended, just be aware that more and more resources are being used and the planet can't give much more.
 and your example of planting trees is manipulation.
No offense taken... discussion is how we learn. This is not the proper venue for a subject that takes time (and resources), which is why I gave only one small example to illustrate. Breifly however, it has also been shown that enough food can be produced for all of us in a surprisingly small area, and minerals... we have barely scratched the surface (of the Earth)! If one looks at the best scientific data from each decade re: resources, for most, we find there is more and more each time. Did these minerals and resources magically appear? Of course not, but it demonstrates that Man is able to find more by either digging deeper, or using new technology to find them, or extract better, or find replacements. We do not need to use up a billion acres for grapes to get resveratrol because it can be made cheaply, en masse, from the root of knotwood, for example, or the transformation of used tetra-pak boxes (which are transported empty ~1 million per single semi truck as opposed to about 16 trucks to haul the same in glass, along with the wearing out of more tires, brakes, driver's backs, etc) into "fake" wood for decks and docks, etc.
Compare the resources needed to produce a Sansa Clip as opposed to a reel-to-reel tape deck of a few decades ago. Or the PC you are using now compared to the vast resources needed to produce a single computer of decades past. Man's mind is The Ultimate Resource. In fact check out (as a starting point) the paper by that name by Julian Simon, who refuted the Malthusian POV quite well.
Bottom line, you can live the way you believe and not buy these planks, and be consistent at least, and I admire that, and I will live based on my extensive research, study and thought on the matter, and I too will be consistent and enjoy cooking on these planks. I hope you are not going to huddle and shiver in some primitive third world hut to "save the resources", but I would never try to stop you, and expect the same from you.
