Trees for the Future has assisted more than 170,000 families, in 6,800 villages of Asia, Africa and the Americas, to plant over 35 million trees. [160] Ecologi is an organization that offers its members ways to support climate change solutions. This includes offsetting their carbon emissions and tree planting.

In September 2019, the Plant-for-the-Planet app was released under an open-source license. It allowed users to register planted trees or to plant trees by donating to different tree-planting organizations around the world. [24] The foundation does not take any commissions for donations made through the campaign. [25]
Major uses of forests include timber production, recreation, hunting, fishing, watershed and fisheries protection, wildlife habitat and biodiversity protection, and gathering nontimber products such as berries, mushrooms, and medicinal plants. [1] There are boreal forests in Alaska. [4] Forests in Hawaii and the U.S. territories are tropical. [5]
Its old age is a result of harsh weather and a lack of nutrients, which slow down the decaying process. [5] The tree's name refers to the biblical patriarch Methuselah , who is said to have reached 969 years of age before his death, thus becoming synonymous with longevity or old age in many European languages including English.
