"the lumber industry gets the bulk of their wood from farms and tracts that are continusouly replanted"
I believe most commercial logging is clear cut. This is devastating to not only trees, but soil, animals, watersheds, migratory birds, and who knows what else down the line.
We need wood, so we have a lumber industry that grows trees and cuts them down. But don't think for a second that replanting a clear cut wasteland with monoculture seedlings is in any way "renewable" or "encouraged".
If you have any doubt about the effectiveness of replanting, zoom in and around British Columbia with google maps. What appears to be a massive unbroken forest is actually riddled with clearcuts.
That's because there are none left. Check out the maps over time here.
