Thank you again. We have Helen Clark here, who has just spoken at our panel at Davos. And one of, I guess, the key questions-- you've worked a great deal in the public sector, but your recent piece on insurance, on communities, also emphasizes the role of the private sector. So here we are at Davos. Can you talk a little bit about what the private sector's role is in improving health in the face of climate change?

I believe that how the private sector does business is going to have such a huge bearing on climate action and on working on other environmental threats. I think with respect to the health sector, the insurance area can bring new perspectives to health systems and all of those operating in the health arena. Insurance is about assessing risk.

And if you know your risk, you can address it. If you don't know your risk, you're walking blind into what might be coming down the track at you. So from my UNDP days, I've been in discussion with the insurance sector about how their skills can help drive climate action by everyone. Of course, alerting governments, but also alerting all the clients to what they need to do.

Today we talked a lot actually, about how do we get these innovations to the people? And we talked about community health workers. These are folks who are bringing vital services directly to their neighbors' doorsteps, and they're really at the front lines of our fight against a warming world. Because community health workers are responding to extreme weather events, they're maintaining speed and service of care during pandemics. They're actually our largest pandemic detection network, and yet so many community health workers are not set up for success.

It's a real shock to most people to understand that around the world, community health workers are out of stock a third of the time. In Africa, 86% on salaried. And so we have a real opportunity here. And actually, the opportunity cost is growing with climate change not having these basics in place, because now we're not just missing a single flu case in a far off village. We're actually endangering children around the world because we have this pandemic detection network that we're effectively leaving unplugged.

43 countries now recognize community health workers as salaried, skilled professionals, and I think there's a real opportunity to partner up to double that number and fight climate change in the process.
