Trees aid in reducing carbon dioxide and other greenhouse gases from the air, which cools the Earth. The carbon storage capacity of forests is approximately three times as large as the pool of carbon in the atmosphere. If forests are changed, reduced, or eliminated, the captured carbon goes into the atmosphere as carbon dioxide. The carbon release from deforestation accounts for 25 to 30 percent of the four to five billion tons of carbon accumulating every year in the atmosphere from human activities.
The shade of trees reduce the amount of heat absorbed by homes and buildings, thereby reducing energy demand for air conditioning. Trees also act as windbreaks during the winter, thus softening cold winds. This also helps people save on utility costs. Evapotranspiration from tree leaves turns water from liquid to vapor tat results in cooling the air. Therefore, reducing the heat island effect.
By educating communities through our tree planting events, we are essentially passing knowledge to help people significantly increase their financial stability, give access to more nutritious food to eat, security from risks related to markets, pests, and weather extremes, free alternatives to pesticides and fertilizers, feed for livestock, fuel wood to cook, and promote sustainability.
Scientific studies confirm that trees in cities provide social and psychological benefits. Humans derive substantial pleasure from trees, whether it is inspiration from their beauty, a spiritual connection, or a sense of meaning. Views of nature reduce stress response by both body and mind. Urban green also appears to have positive effects on the human immune system.
Research in public housing complexes found that outdoor spaces with trees were used significantly more often than spaces without trees. Trees facilitate interactions among residents, which can contribute to reduced levels of domestic violence, plus foster safer and more sociable neighborhood environments.
One large tree has the capacity to filter up to 36,500 gallons per year. On average, a mature tree can absorb 36% of the rainfall it comes in contact with. Forests can capture rain in the canopy that reduces flooding and stormwater runoff. Forests help improve water quality by extracting pollutants from its tree roots.
