That's not logical. Just because a disaster was made by machines doesn't mean machines are the solution.

"Fewer machines" would be a great solution, which I think might have been the point?

No, I'm saying the scale of the cause of problem vs this guy's tiny sand solution seems out of whack.

Sand won't stop millions of carbon emitting cars on the road. We need bigger solutions.

I have to ask: do you think 30 billion tons of olivine annually is a "tiny sand solution"?
