Forests’ Countless Benefits

Home to 1.6 billion people and 80% of all plant and animal species, our world’s forests are the cornerstone of life itself.

They provide us with countless benefits — some of which you might not even realize.

Cleaner water and air

Forests help improve water quality in streams, rivers, and lakes, as well as filter pollutants out of the air.

Carbon sequestration

Trees are one of our greatest weapons in the fight against climate change. In the United States, national forests alone absorb more than 50 million metric tons of carbon each year.

Climate regulation

Forests increase rainfall, prevent drought, and cool the overall temperature of the planet.

Habitat for wildlife

Animal species of all kinds rely on forests for food, shelter, and water.

Food security

Fruit and nut trees are an important food source for millions of people across the globe.

Recreation and wellness

From camping to fishing to hiking, forests provide us with opportunities to connect with nature and one another.

An Urgent Need

The world has lost an estimated 1 billion acres of forest since 1990. This staggering rate can be attributed to a number of factors:


Human activity is one of the greatest contributors to forest loss. Around the globe, trees are cut down for agriculture, cattle ranching, development, and logging. Deforestation has had the most significant impact in tropical rain forests, which are at risk of disappearing completely in 100 years.


Diseases like sudden oak death, spruce decline, and white pine blister can cause significant decline in previously healthy forests.


Infestations by insects like the mountain pine beetle have reached epidemic levels in select forests, killing hundreds of thousands of trees and making the area more susceptible to fire.


Wildfires are a natural part of many ecosystems, helping promote vegetation growth by clearing away dead material. However, with climate change creating hotter and drier conditions, these fires are growing in intensity.


Increasingly severe weather like hurricanes, ice storms, high winds, and drought can wreak havoc on forests.

Our Reforestation Work

Together with our network of planting partners, we’ve made great strides in global reforestation since our founding more than 50 years ago. We’re proud to have planted hundreds of millions of trees in forests across geographies, soil types, climates, and countries — and we’re just getting started. Join us as we plant another 500 million trees by 2027.
