This has been an entertaining read. Existence on Geo-engineering to save the world:
Even the most ecological ideas have critics. Fertilizing vast “desert” stretches of ocean would seem an obvious win-win, expanding the food chain and much-needed fisheries while sucking atmospheric carbon. Crude attempts with iron powder caused problems. But what of using tidal energy to stir ocean bottoms, exactly like natural currents? Suppose a naturalistic solution worked! Might we think ourselves wise enough to manage a complex planet? The New Puritans say our best course is to “do less harm” in the first place. But can we only fix our messes through rigid self-denial? Is there no role for the trait that took us from the caves? The can-do spirit of ambition?
