Birds.
Fish.
Insects.
Coral.
Arable land.
Drinkable water.
What do they all have in common?
They are disappearing so fast that it will make your head spin if you think about what that means...
For those unwilling or unable to follow along at home...with no base, the food chain becomes unstable and untenable.
For EVERYONE.
There is not going to be any way to replace the benefits of insect pollination.
There is no way to feed fisheries and schools of fish without a base of plankton, krill and tiny feeder fish.
There is no chance to support 10 Billion people with disappearing arable land and toxic dead zones from fertilizer run offs.
There will not be anything resembling the current social structure when this is all sorted out in reality and divorced from political arguments and fantasy thinking.
Starving people generally are very dangerous.
Human society (and the basis for the global economy) are going to meet reality soon. The fantastic wealth accumulation across the globe to put control of 99% of resources under less than 0.5% of the population is an untenable situation, period. Capitalism, unfettered and unregulated, will only make that worse until the riots and refugee wars start in earnest.
There are estimates that the natural world provides TRILLIONS of dollars of free economic aid to the global economy. TRILLIONS. Now think about the distribution of wealth on this fucking PLANET right now. The top 0.5% of EVERYONE owns or controls nearly 90% (or more) of the total wealth, leaving BILLIONS of people with little to nothing.
All I can say is for the rich asshats buying land in New Zealand or underground bunkers with private security forces, karma is a bitch and she is always paid in the end. No one gets out of here alive indeed...but the way they go can be determined from how poorly they treat their fellow man too. Without a strong, local support structure and communal lifestyle, humanity is going bye-bye just like everything else in this 6th mass extinction.
