Privacy Statement Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it s the only thing that ever has. Youth Group Activity Trees and the Environment Trees produce life-giving oxygen and remove air pollution as they lower air temperature, release moisture into the air, and retain particulates. Trees prevent erosion by holding soil in place and slowing runoff from storms, allowing rainfall to percolate into the soil. Along streams trees help reduce floods and erosion by slowing water and trapping sediments.
Trees provide shelter and food to a variety of birds and other wildlife.
