So shooting for one planet just means you would be totally dominant, and leave no space for other species. Ecologists say to maintain 85% of preindustrial biodiversity, it would take about at least half the planet left on its own. That would mean getting to half-planet. And now we use at least 1.75. I say at least because our assessments with about 15,000 data points per country in a year are based on UN statistics, and their demand side is probably an underestimate because not all demands are included. And also on the supply side or the regeneration side, the UN is very production oriented, so it's the FAO numbers, for example, look at agricultural production, and the depletion side or the destruction side is not factored in adequately. So that's why it's an underestimate. And still, it shows we use about 1.75 Earths, and that's more than three times half an Earth. So that's kind of the difference. But we also know overshoot will end one way or another. The question is do we choose to end it? Do we choose it by design, or do we let nature take the lead and end overshoot by disaster? So it's really ending overshoot by design or disaster. That's the big choice we need to make.

I think water is taking a backseat and personally, I feel like water is the messenger that delivers the bad news of climate change to your front door. So in the work that I do, it's heavily intertwined, but it's taking a backseat. There are parts about water that are maybe separate from climate change, and that could be the quality discussions, the infrastructure discussions, although they are somewhat loosely related to climate change and they are impacted by climate change. That's sometimes part of the reason why it gets split off because it's thought of as maybe an infrastructure problem, but you know, the changing extremes, the aridification of the West, the increasing frequency, the increasing droughts, these broad global patterns that I've been talking about, that I've been looking at with my research – that's all climate change. Just 100% climate change, a hundred percent human-driven. And so it does need to be elevated in these climate change discussions.
