“Humanity’s current path will push societies into deeper crises unless we make major changes. The planet’s life support systems are already under strain &, without rapid shifts in how we use energy, land, & food, billions of ppl will face increasing instability.” #FossilFuel induced #ClimateChange
Article excerpt 
If one adds progressive breakdown of global food and water systems, overheating of the climate, state failures, the global rise in authoritarian governments and spontaneous wars (possibly nuclear), the projection of 1.2
billion migrants in 2050 is starting to look very conservative. If the forecast by. British actuaries is borne out, of 2-4 billion dead, then the mass migration
preceding it will involve more than half the world's population.

What infuriates me is not only that we're poisoning our own water supply but also the water for all other species. "Humanity unthinkingly emits more than 220 billion tonnes of chemically-active substances every year into the environment – and most of them end up in water by one route or another."

Having slain over 200 million people since 1850, it is arguable that the nation state is the most destructive invention humans have ever made – and maybe it is now time to consign it to the garbage tip of history before it destroys us all.

Water bankruptcy is no longer a future threat
Across large parts of the world, water demand now permanently exceeds supply. This is not a temporary crisis but a condition of irreversible scarcity driven by overuse, climate change and population pressure.
