So we have you to blame for coral reefs dying

Coral reefs are dying because of the water temperature increase coupled with increased acidity. And that happens not because someone uses a dishwasher detergent, they are likely not even in the same hemisphere. But because none of the governments are implementing any working green tech at scale, so the emissions are only ever increasing and the rates of increase is accelerating. Paper straws and bad detergent won't help when new coal and gas plants are constructed daily.

Probably not I have a septic system.
