Water: it's a survival emperative - without it all biological life dies. It's also becoming a very scarce resource via pollution & climate change, awa escalating water over usage (much of it very wasteful). Much water is used to grow food, a large proportion of that to raise livestock. Question: if everybody is dead will we still need green hydrogen to fly empty planes to go on holiday & fuel cargo ships to bring dead people their stuff?! Perhaps we need to rethink our priorities...
