 Anna, can I turn it over to you to add your thoughts? Thanks, Navrose. So a couple of points here as people talked about diversity, whether there was going to be greater extinction as a consequence of, am I paraphrasing or have I gotten it completely wrong? So I say, yes. OK, so I'm going to take off from there because it also ties in very nicely with Navrose's question to me. And so let's step back a little bit. I think the evidence now is pretty much established that, yes, anthropogenic climate change is occurring. Michael Mann, who's an expert in this space, was at the US Senate very recently. And he's got this wonderful book, if you all want to look at it, which is called Climate Madness, where he's collaborated also with the New Yorker cartoonist, where he said that 97% of the scientists in the world agree that there is anthropogenic climate change. Despite the president of the United States, I think we can all agree on that. The reason that we are still at a space of inaction is because we are still trying to figure out what to do. And I think I'm much more sanguine than a lot of people in this space because I think there is a light at the end of this tunnel. Daniel Kahnman and Amos Tavarsky have done a lot of work in what is now called behavioral science or behavioral economics. And what it says is that also Daniel Kahnman is the, I think, one of the very few Nobel Prize winners in economics, although his actual training is in psychology. And what they find is that people react to many other things other than just evidence and knowledge. Evidence and knowledge is one thing. But because of inertia, because people don't want to change their behavior, et cetera, you need other nudges. And there is now an entire school of thought that is basically building on this. You have what is called the Behavioral Insights Team, which was started by David Cameron in the UK, which has now experimented with very, very easy, simple things so that you can change behavior. For example, sending people letters which say, oh, you haven't paid your taxes. Guess what? People who get these letters usually pay their taxes on time. It changed tax-paying behavior from people who had been defaulting repeatedly, dramatically, just because people don't want to look bad. So I think there is now a lot of research being done in what can induce better and more responsible action. We have to spend time and money doing it.
