Trees help clean the air we breathe, filter the water we drink, and provide habitat to over 80% of the world’s terrestrial biodiversity.
Forests provide jobs to over 1.6 billion people, absorb harmful carbon from the atmosphere, and are key ingredients in 25% of all medicines. Have you ever taken an Aspirin? It comes from the bark of a tree!
Trees help to clean the air we breathe. Through their leaves and bark, they absorb harmful pollutants and release clean oxygen for us to breathe. In urban environments, trees absorb pollutant gases like nitrogen oxides, ozone, and carbon monoxide, and sweep up particles like dust and smoke. Increasing levels of carbon dioxide caused by deforestation and fossil fuel combustion trap heat in the atmosphere. Healthy, strong trees act as carbon sinks, offset carbon and reducing the effects of climate change.
Trees play a key role in capturing rainwater and reducing the risk of natural disasters like floods and landslides. Their intricate root systems act like filters, removing pollutants and slowing down the water’s absorption into the soil. This process prevents harmful waterslide erosion and reduces the risk of over-saturation and flooding
A single tree can be home to hundreds of species of insect, fungi, moss, mammals, and plants. Depending on the kind of food and shelter they need, different forest animals require different types of habitat. Without trees, forest creatures would have nowhere to call home.
TREES COOL THE STREETS AND THE CITY
Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.
TREES ADD UNITY
Trees as landmarks can give a neighborhood a new identity and encourage civic pride.
TREES PROVIDE A CANOPY AND HABITAT FOR WILDLIFE
Sycamore and oak are among the many urban species that provide excellent urban homes for birds, bees, possums and squirrels.
