The leaves capture particulates like dust, soot, and pollen and remove them from the air. They also remove and store carbon and reduce our need for energy. Trees act like a carbon warehouse. In the process of photosynthesis, plants remove carbon dioxide from the air and release oxygen. A healthy tree uses over 20 lbs. of carbon dioxide each year.
Carbon dioxide is the most common greenhouse gas.
Trees are outdoor air conditioners. They provide a natural way to shade and cool your house in summer and can shield your home from the cold winds of winter. A person can save energy by landscaping with trees. Deciduous trees planted on the south, west, and east will protect your home from the direct rays of the sun in summer. In winter, without their leaves, they allow most of the sun s energy to reach the house.
