I won't start ranting about it because I just get myself worked up, but quickly: I literally can not think of an investment of public funds that has a higher return than *cleaning the indoor air in schools*. It's so easy, so cheap, & has such HUGE payoff. Criminal that we basically don't do it.

Not sure if the canary pins will be made widely available at some point (I hope so!) but you can keep an eye on www.airclub.org

To get clean air infrastructure everywhere, we need as many governments, states, cities, nonprofits, schools, businesses etc. to sign on as possible. Please read the pledge, share it, and push your local orgs to join!
