Thank you.
With respect to greenhouse gas emissions, would anybody like to speak to the considerations around acidification and pH concerns as they apply to more traditionally waterborne pollutants?
I'll tell you where I'm going with this, because I might run out of time. Plastic pollution in water has always been considered to be something you can see. People walk by a stream or on a beach, and they'll pick up plastic pollution. CO2 is very different. Other emissions, like methane, are invisible. We don't see them, but they have a really negative impact on our natural environment and on climate change.
PFAS are the worst of both. They're invisible, they have a really negative impact and they're much more difficult to clean up. They may be as hard to clean up as CO2 is to remove from the atmosphere.
Do you have any reflections on that relationship?
