From the Ted Talk "Tim Kruger: Can we stop climate change by removing CO2 from the air?"

Unscramble the Blue Letters

Tim Kruger: So I think you need to do a rieess of experiments, but you need to do them just very small stage-by-stage. In the same way, when you're trialing a new drug, you wouldn't just go into human trials straight off. You would do a small experiment. And so the first things to do are experiments entirely on land, in special ctaornnies, away from the environment. And then once you are niotnecdf that that can be done safely, you move to the next stage. If you're not confident, you don't. But step by step.
