15 billion trees are cut down each year.

Less than 4 billion are planted.

11 billion are never replaced.

One by one, we can change this.

One by one, we can save our planet.

Human civilization has lead to an enormous tree debt of more than 3 trillion. We must dig our way out of this.

This means ONE TREE per person, per year.

That's right. 7 billion trees, every year. We will plant them for you. But we can't do it without you.

Those are BIG numbers! But why care?

Earth, at its healthiest, had about 6 trillion trees. We’re now down to 3 trillion. Trees are the lungs of our planet. Earth is surviving on 50 percent “lung capacity." Trees purify and cool our atmosphere. If we fail to slow deforestation, the tree population in 100 years will plummet to 2 trillion. This puts our ecosystem below a precarious 30 percent lung capacity.

If we do nothing, we face ecosystem collapse and mass extinction in 100 years. That's just two generations. We must reverse course. We must act now. We must each make the promise of one tree per-year.


This is not a hopeless cause. Trees will do their part.

Planting 7 billion trees annually is physically impossible. Global efforts of this scale are complex. We will not reach every person. Most will not help. But some will. Some will contribute more than one tree.

The nice thing about trees, they really want to be here. Trees drop countless seeds each year. 99.9% of those seeds never become trees. We have the amazing ability to change that. We can nurture seeds into viable trees. If we reach HALF our goal, we will plant more trees than any group on earth. Maybe, just maybe, we can maintain the current state of our planet without more significant decline.

Support our very first Kickstarter!

Be Totes for the Trees!

Dear One Tree Friends: Please Like & Share! We’re asking for your support of our very first Kickstarter campaign. Our aim is to fund the manufacturing of two higher-end grocery tote bags to reduce single-use plastic bags in exchange for sponsoring a planted trees in South Florida. We're calling the project “Totes for the Trees.”

Donation reward? A reusable, sustainable, grocery tote of your choice (or both!) - one from an award-winning landscape photographer and another from the design pros at Go Media.

Check it out & if you believe in the cause, please consider a Like, Share and/or Donation!

If we rock this, we’ll make it an ongoing project with regularly-updated designs/photos/art.

Thank you so very much!

Paying for trees, transportation, and supplies is our most significant and ongoing need.

Donations of labor are our second most essential contribution. The more volunteers we have, the more trees we can plant, faster.

Land Access rights

Join our 50+50 program to allow (re)foresting of your property, lot or corridor. A minimum 1/4th acre is required to support our minimum of 50 trees.

Understanding the Science

As with anything human-caused, there is often skepticism and differing views on cause and effect. It is literally very difficult to "see the forest for the trees". On top of this, no single organization has the ability to go around accounting for every tree on the planet. However, thanks to modern technology such as satellite imagery, we're now gathering a better sense of our impact on the planet.

Everything about tree statistics is extremely approximate. We've placed conservative estimates on all of our figures. Unfortunately, this means our numbers are exceedingly optimistic, and they're still severely alarming.

One Tree is a new group founded in Fort Myers, Florida USA. Florida is currently our primary planting region. Thanks to various local sponsors, we have planted over 10,000 trees. We have come to realize much more are needed and they must be planted faster.
