Why do trees help our health? The study team from the University of Chicago in 2015 only had educated guesses. But these include the fact that trees reduce air pollution, cool the summer air, and have a hard-to-measure — but very real — stress-busting ability.⁠ ⁠ There’s a hint in the study that evergreens may help us more than deciduous trees, but the team isn’t sure.⁠ The study concludes that adding 10 trees per block to tree-deprived neighborhoods would involve boosting Toronto’s overall number of trees by some four percent. That, says the team, is not too lofty a target. The researchers are looking at further things that trees and other natural surroundings can do.⁠ ⁠ ⁠ ⁠ ⁠ #treehouse #trees #tree #forest #science #biology ⁠
