Somewhere off the coast of Mexico, a vessel moves slowly through open water. It’s not fishing. It’s not surveying. It’s hunting seaweed. Why? To take carbon out of the atmosphere, while buying fragile coastlines a little more time. That vessel is the latest chapter in a story that started 25 years ago, underwater. A career…

Bamboo Village Uganda develops several bamboo afforestation projects in Uganda. Bamboo acts as a natural carbon sink: it removes CO2 emitted from the atmosphere and stores it in the soil and the plant. The benefits of Bamboo Village Uganda’s project extend beyond environmental impact. The project actively invests in the local community and generates a…
