Meritt Herald: Coral Reefs, assisted evolution and geo-engineering

The word for this, if we are being honest, is ‘geo-engineering.’ It’s a very gentle, low-tech kind of geo-engineering, with relatively little chance of major negative side-effects if we get it wrong. We are definitely still on the learner slopes. The interventions in natural systems will get much bigger, and the penalties for mistakes much more costly, as time goes on.
