Living filters

Forests are “living filters” for rivers and streams — absorbing sediments and storing and transforming excess nutrients and pollutants. They can reduce nitrogen and phosphorous concentrations by up to 99 percent.1 Tweet this fact »

Unmatched biodiversity

Tropical forests cover roughly 10 percent of Earth’s land mass but are home to at least half of all living species2, 3, 4 on the planet. Tweet this fact »

Populations in perspective

An estimated 350 million people around the world depend on forests for their livelihoods5, 6, 7 — more than the population of the United States. Tweet this fact »

 

HELP US PROTECT FORESTS

No amount of innovation or technology can replace the life-giving functions that forests provide for people and the planet. In fact, it’s easier to save forests than to replace them. You can help protect an acre now for only $25.

Successful stewardship

Indigenous peoples manage or have rights over about 40 percent of all terrestrial protected areas and ecologically intact landscapes8 — and their lands have lower rates of deforestation and fire than other protected areas. Tweet this fact »

Forests need animals

Up to 90 percent of trees and plants in tropical forests rely on animals to propagate their seeds. The loss of species due to human activities could impact tropical forests’ ability to store carbon9 — a critical role in the fight against climate change. Tweet this fact »​​​

Forests growing younger

Globally, forests are getting younger and shorter as large, old trees die faster than they used to.10 This limits the amount of carbon those ecosystems can store. Tweet this fact »​​​

Destination restoration

In the United States, there are up to 52 million hectares (127 million acres) of previously forested land that, if restored, could capture 314 million tons of carbon dioxide — equivalent to removing 67 million cars from the road each year. Tweet this fact »​​​

A nod to Norway

In 2016, Norway became the first country in the world to cut public procurement contracts for companies that contribute to deforestation11 — an important step in the fight against climate change. Tweet this fact »
