The air we breathe is purified by trees. Trees absorb toxic pollutant s in the air and filter particulates out of the air by trapping them on their leaves and bark.10 trees can remove 20 pounds of pollutants annually.
Trees retain water through their roots, prevent soil erosion, flooding, retain ground water, and also purify water as water seeps through their roots.
Trees hold carbon monoxide that acts as a natural coolant to our environment. This stabilizes the climate. Trees can cool our city by as much as 10%
Being around with trees can reduce stress, and tree shaded walkways encourage people to walk and exercise more.
