I don't think crowd-funded organizations will totally replace the government, I do think they will start taking action where the government has failed or enables the bad actors. I feel that there are plenty of business opportunities for companies that want to improve the world instead of destroying it. Your example is a great example.

I've been thinking a lot lately about starting a company that focuses on improving water quality, working with waste water treatment, and working on CO2. Going forward I think this problem will continue to get worse and there needs to be companies that are trying to solve these issues.
