Trees absorb pollutants and gases that exist in the environment. They do this by absorbing these chemicals in their leaves and barks. Common gases that are taken up by trees include ozone, sulfur dioxide, nitrogen dioxide and ammonia. By doing this, trees help to combat the greenhouse effect, a phenomena that results in rising temperatures on the Earth.

Trees are a natural source of nutrients for many organisms that inhabit the Earth. This allows the organisms to subsist from these natural plants rather than resorting to artificial sources that result in more resources being used. Trees provide oxygen, a nutrient that is necessary for life to exist. Trees provide shade to both animals and people and assist with cooling needs during the warmer months. This results in less energy being used to cool homes and commercial buildings. The shading from trees also helps to conserve water, as the cooling slows the rate of evaporation.
