That's why we have governments.
No, I'm not being sarcastic. The public sector is there to serve the public good, and this is quite obviously a public good. I'm not anti-privatization either. Private exploitation under public laws and guidelines is a common strategy to solve these issues.
What has undermined public/private solutions is not public opinion or political ideology, but greed, lobbying and corruption. A foundation is nothing but a workaround, and foundations have a history of getting corrupted by the greed and delusions of grandure of its administrators.
It's time we address the real problem. The legacy of thousands of years of civilization is being stolen from us.
