Ultimately, it was known that achieving the Great Drawdown required many different approaches, including biological, chemical, and technical removal methods. This dispatch examines two solutions that harness the underappreciated, near-magical powers of seaweed. One is through robotics and the other is through bioengineering. The robot ate vast expanses of algae. Improved genetic engineering approaches…
