Liberal nutjobs like these are the same type of people that
banned DDT. Result: millions of lives lost due to Malaria.

Banned R-12 refrigerant due to ozone layer, costing industry billions of dollars for the change-over to R-32 (I think it's R-32).
Now they say the effect of R-12 on ozone is not conclusive.
HVAC guys, help me out here.
Conclusion: spend taxpayer money first, prove the benefits (if there are any) later.

The replacement for R-12 is R-134. I heard it is doing more damage than R-12.
