No in my world we don't delay the process of stopping to destroy our planet over some minor concerns that are typically raised by people who argue against this because they want to continue burning stuff and slow down the demise of the fossil fuel industry. These people don't actually care about our planet, the environment, or any of this. And I suspect your concern is disingenuous.

So in your world, we make no attempt to improve anything unless we can achieve 100% perfection? Sounds like a terrible plan.
