Replanting trees in deforested areas is also crucial. Although this seems like a very long-term solution, replanting actually makes an almost immediate impact. Tree seedlings planted in tropical or semi-tropical environments grow very rapidly - seedlings planted now will be towering trees in only a few years. Also, trees in their first few years of life absorb more CO2 than when they are mature.
There are many ways you can make a difference in keeping our forests healthy. Use recycled paper whenever you can, and recycle the paper, paperboard, and cardboard that you use. Of course, planting trees is always a good idea! You can even have trees planted to offset the paper you use. Planting a tree is not only an investment in the future, but an important way to help keep the planet healthy.
