Why we love trees


Trees give life

Trees increase biodiversity by supporting life for millions of organisms above and below the ground. From microscopic fungi and mycelia to birds, insects, mammals, and human beings, forests provide shelter, food, and medicine for many living creatures.

Trees sequester carbon

Trees cool our planet through the process of respiration, breathing carbon and exhaling oxygen. In just a year, a single mature tree can sequester 48 pounds of carbon while an acre of a forest can absorb around 30,000 pounds.

Trees keep oceans clean

Forests prevent runoff from reaching our coasts. They also cycle vital nutrients through coastal marine ecosystems, promoting healthy oceans, fish, and a healthy you.

Trees promote wellbeing

Taking a walk through the forest is scientifically proven to relax the body, the mind and strengthen your immune system. This is because trees produce medicinal aerosols and stimulate your “rest-and-digest” nervous system.

Trees Benefit the economy

The presence of trees in a commercial area  increases real estate value and promotes more consumer spending.  Tree canopies also attract new business and tourism, reduce crime rates, and retain long-term renters.

Trees cool our cities

The temperature in some American cities has increased 4 degrees since 1970. Trees can offset this through their ability to absorb 90% of solar radiation and transpire water, promoting an overall "cooling effect" in the air.


I want to remind you that the forest is far more than a source of timber. It is our collective medicine cabinet. It is our lungs. It is the regulatory system for our climate and our oceans. It is the mantle of our planet. It is the health and well-being of our children and grandchildren. It is our sacred home. It is our salvation.
