      Well, I can tell you why we need them. Trees photosynthesise and produce the oxygen that we need to survive! We then breathe out carbon dioxide and the trees ‘breathe’ that in. It’s a nice balancing act 🙂

      As Sarah says, trees our essential for our breathable atmosphere. The UK used to be covered in trees but a lot were felled for farmland. And the Amazon rainforest is being felled at an incredible rate, so its important to fight to keep our trees!

      We seem to have them because they evolved to fill a niche in the environment – we had a lot of carbon dioxide in the atmosphere, which plants and trees love, and so they could grow and develop into new and bigger forms – eventually we wound up with the trees we can recognize now! Even now they serve a critical purpose in clearing carbon dioxide from our atmosphere.
