0% chance of side effects is unrealistic. A better way to think of it is like the hippocratic oath that doctors adhere to: to do no harm.

Yet just a few weeks ago a doctor cut some holes in me. That’s clearly harmful, yet in the balance I was quite glad he did so sad that way he could repair my arm. So a trade off analysis is required.

Fortunately there’s a emerging governance, e.g. from the Climate Restoration Safety and Governance Board that’s just starting up. It already has a pipeline of projects waiting to apply for regulation.
