Trees are nature's soldiers in the fight against global warming. As they feed themselves, they absorb carbon dioxide from the atmosphere and store it in the form of carbohydrates. The stored carbon remains locked inside the body of tree, keeping it out of the atmosphere. Since carbon dioxide is one of the most common greenhouse gases, planting trees can help put the brakes on thegreenhouse effect.
Trees also improve air quality by producing oxygen as a byproduct of photosynthesis. One full-grown tree puts out enough oxygen each year for twohuman beings.
In addition to cleaning up the air, trees also clean up the soil and surrounding groundwater. The roots help clean and filter the rainwater that eventually runs off into our waterways. They also absorb unwanted chemicals from the surrounding soil. Trees can help clean up farm wastes, heavy metals, and sewage, among other waste products.
Trees also provide a source of food and shelter for a variety of wildlife. Many different types of animals live in or around trees- for example, birds and squirrels nest in the branches, and burrowing animals such as rabbits sometimes live amongst the roots. The type of tree, as well as its age, size and physical characteristics, determines what kind of wildlife it can support. Trees are also an invaluable food source, providing fruit, nuts, leaves, berries and insects to many different types of creatures.
