Which trees give off the most oxygen?Pines are at the bottom of the list in terms of oxygen release because they have a low Leaf Area Index.Oak and aspen are intermediate in terms of oxygen release.Douglas-fir, spruce, true fir, beech, and maple are toward the top of the list for oxygen release.
How did trees come to earth?
But the truth is, trees are actually formed largely out of the air. (Yes, air!) Trees, and all photosynthesizing plants, use the energy of the sun to split atmospheric carbon dioxide into its constituents: oxygen and carbon. And carbon is the primary building block of the tree — and all of life on earth, too.
