Reddit's Former CEO Is Now In the Forest-Planting Business (fastcompany.com) 33

Terraformation, a startup led by Yishan Wong, former CEO of Reddit, is demonstrating an approach to reforest the planet quickly enough to fight climate change. Fast Company reports: Trees can play a key role in capturing carbon at scale -- by one estimate, nearly a trillion hectares of land could feasibly be reforested, and those trees could potentially store more than 200 gigatons of carbon. But efforts at reforestation are moving too slowly. "Essentially, we need to scale the solution in about 10 years, so that there is time for the forest to mature and become a carbon sink of reasonable size to meet various nations' commitments to be net zero around 2040 or 2050," says Yishan Wong, CEO of the Hawaii-based startup, called Terraformation.

One of the challenges the company identified was the lack of land: Some land that was originally forested is now covered by cities or used for farming. Other areas might not be available for sale. But there's a large amount of desertified land that is available. The United Nations Convention to Combat Desertification reports that around 4.7 billion acres on the planet -- about twice the size of China -- have been affected by drought or desertification, but could potentially be restored. Finding enough water to grow trees there is a challenge. But the folks at Terraformation believe that if desalinated water is used to irrigate seedlings, a restored forest will eventually be able to sustain itself.

In Hawaii, the startup built the world's largest fully off-grid, solar-powered desalination system. With a half-acre of solar panels, there's enough power to desalinate around 34,000 gallons of water per day, taken from a well on the site. A drip irrigation system sends the water to the roughly 1,900 native trees and shrubs that have been planted in the area so far. As the forest grows, proving that the system works, the company is working to replicate the same idea around the world. It's creating seed banks that fit inside shipping containers and can store the millions of native seeds that are necessary for large planting projects. It's also building open-source software that groups can use to collect data and track progress after trees are planted.

  • All those millions of years ... before us, where they were totally helpless and couldn't spread saplings by themselves . . .
    Oh the treemanity!

    But at least somebody can compensate his bad feelings for not actually stopping the cutting down of ancient rain forest, and feel virtuous for replacing it with a otherwise dead monoculture that will be just as natural in, what, 800 years...

  • Instead of using solar panels to desalinate water and grow trees, use those solar panels for replacing current coal fired plants.

    Trees are inefficient (around 3%) at converting solar energy even without the extra effort of desalinating water.

  • The problem with forests in a warming climate they tend to burn quickly.
    Better to replace deserts with grassland, traps more CO2/m^2.

  • There are trees, that can do all of this themselves [discovermagazine.com]. Why not plant those?

      Speed. We are now over the critical point. Dragging world climate back into the safe area will be a massive effort and has to be done pretty fast.

      • Why? Climate Change really upsets SIWs so we should do a lot more of it. Now off to put more coal on the fire, gonna mine some more Bitcoin with goal power, then drive my V8 wherever I like for as far as I like. If you Leftist SJWs had treated your opponents with respect you might have more chance of bringing people like me on board. But you couldnâ(TM)t bring yourself to compromise so thwarting your aims is going to be a pleasure.
    • because those are native to a tiny slice of the planet, and they are trying to use trees natives to the area they are re-foresting.
    • On mountain tops where salt water is far away, and the native species could not do it by themselves, this can be used: https://en.wikipedia.org/wiki/... [wikipedia.org]
  • Now if only those intensive agricultural practices did not denude the subsoil of it valuable microbial life through tilling, synthetic fertilizers, Roundup, etc. then maybe we'd also have some more carbon sequestration in agricultural lands. (And healthier more productive plants too, since the soil bacteria, fungi etc. are quite important for plants' nutrient uptake.)

    How much? That is a good question that I'm unable to answer, and would probably depend a lot on specific circumstances. But the Wikipedia ar

  • Successfully growing trees on a tropical island isn't what I'd call a proof of concept. The ability to desalinate water with solar power isn't in doubt. A bigger problem with recovering desertified land is that all the topsoil is gone.
  • Please enter the biochar industry instead. Its actually a product you can sell and is proper sequestration. Trees only need carbon for their growing periods, die eventually or burn down in fires.

    In the Scottish moorlands, plots planted with trees stored less carbon than untouched lands: Study
    In the Scottish moorlands, experimental areas planted with native trees actually stored less carbon after several decades than untouched plots covered in heather.
    These results are of direct relevance to current policies that promote tree planting under the logic that trees remove carbon from the atmosphere and lock it in their biomass as they grow. This is true, but disregards the role of soil.
    Globally, more carbon is stored in soil than in all the Earth’s plants and the atmosphere combined.
    Planting trees in areas that have never been forested, a practice known as afforestation, can release these carbon stores, resulting in a net loss of carbon from the ecosystem.

    So, assuming that planting trees is better than the desert is just that, an assumption. It needs testing before you end up making things worse.
