Founded in 2009 to stop global warming "in our lifetime," WeForest has restored more than 100,000 hectares across four continents — and it is quietly proving that planting trees was only ever half the job.
Earth Force Technologies is a San Francisco climate-tech company modernizing wildfire prevention. It builds precision-forestry sensors, in-cabin tablets, and a web portal that give crews real-time, tree-level guidance during fuel-treatment work and let administrators oversee far more acres from a desk. By combining teleoperated machinery, jobsite connectivity, and automated reporting, the company aims to make landscape-scale forest treatments faster, safer, and cheaper - so states, federal agencies, and conservation districts can reduce catastrophic fire risk at the pace the crisis demands.
