It’s common knowledge that planting a tree is an eco-friendly action that can help absorb CO2 emissions and release oxygen into the atmosphere. But not all trees are the same, and some absorb more pollution than others due to their genetic makeup, size and shape. For the most bang for the buck, look for trees like black walnut, white pine, scarlet oak, red pine, Ponderosa pine and chestnut trees. They are easy-to-find species, easy to grow and will ultimately be a workhorse tree in your backyard.
