Lumber is cheap while natural forests are being hacked down without being replaced. The supply isn't diminishing in a very visible way.
The coffee quote is on the same rod. Clean a forest, sell the lumber, then use the fertile topsoil to grow coffee or other sorts in untill the nutrition runs out, then you're down to grassland where you can still use as a pasture. Doing it in a balancing way is much more expensive. So, cheaper lumber, coffee and burgers until you run out of land, then the prices are up.
There is only one continent AFAIK that has this in equilibrum.
BTW, there is a lot of lumber available, but the important areas are in S-America, - effective photosyntesis needs warmth and sun.
Lumber will continue to be cheap, at least for Americans, because of the way logging businesses operate. Using lumber leads to more trees being planted, because owners are greedy and want their profits to continue indefinately.
However, everything you've said still does not address the fact that the evironmental groups you're very fond of supporting for their global warming views are the same groups that fund the fight against solutions to deforestation in continents like South America and Africa. I'll give you some examples...
DDT - the studies upon which the laws banning it were completely debunked.. yet it's still illegal, crops that could be protected are not (resulting in more land usage per pound of harvestable food), and millions a year die from Malaria.
Genetically Engineered Food - "environmentalists" or their groups "street teams" will stand outside of a grocery store in skull masks and signs declaring the government is trying to kill you with GE food.... even though the food has passed testing by the EPA, FDA, & USDA. Now, the FDA is good enough to trust for your antibiotics, but they're trying to kill you with GE food? It's a political arguement with little to no basis in reality. This is the same food that can solve world hunger and put a dent in the deforestation that is a problem by again, producing more food per acre, with less susceptability to disease, and draining fewer resources from the soil allowing for faster re-use of the same land.
Behind the vast majority of "environmentalists" is an anti-globalization or "corporate greed" arguement waiting to happen. You've done it yourself going on about cheap coffee and burgers (even though, for example, McDonalds is sourced predominately from established American farms).
There's a place for anti-corporation arguements. The environment is not one of them.
