The major difference is that environmental groups are VOLUNTEER and require DONATIONS. They also plant trees, not for re-supply to be cut down again, but for longevity and to reestablish the eco systems destroyed when the forested area was initially farmed.
Plant A Billion Trees - one dollar at a time - with The Nature Conservancy
5.5 million trees planted in the Atlantic Forest.
Plant a Tree USA, along with the Billion Tree campaign, claims to have planted over
7 billion trees across the globe (one for each person on the planet.

My problem with re-planting is many of these lumbar companies are 1) are destroying eco-systems by tree farming and killing the diversity of forests with small and mature trees by having all plants the same age, 2) cutting down entire forests with many types of trees and re-planting only a single species (the one they want to harvest).
Recently lumbar companies are getting better and I personally don't have a problem with utilizing current tree farms. We realistically require wood for many things. I am just not for expansion into untouched and still naturally wooded areas.
