The Hidden Life of Trees

This was a fascinating book. Trees are amazing. This short book was written in short chapters so it was the perfect science book to dip into here and there for a chapter or two. I learned many interesting things. A smattering:
> Trees need their sleep. Four percent of oak deaths in one American city happened because the trees were subjected to light every night.
> Every day in summer trees release about 29 tons of oxygen per square mile of forest (which is the daily requirement for about 10,000 people). Every walk in the forest is like taking a shower in oxygen. But only during the day.
> Cutting off a tree limb starves a section of the trees roots.
> Compacting the earth around a tree trunk makes it harder for the roots to grow, making the tree less stable. This is a big reason why trees in the city struggle to survive and stay healthy.
