Like the Maya and so many post ice age civilizations that collapsed mainly gue to agricultural soil mineral depletion nd soil fertilixzer phosphorous etc. depletion required to sustain burgeoning population growth so our industrial era consuiong mined fertilizers requiring fossil fuels to strip min them or natural gas to produce nitrogen fertilizer from the nitrogen of the atmosphere,etc. we are on a course that can only led to collapse.And sorry Jesus nor Ala nor that scumbag Jewish god really the same one all these idiot bend over and spred their anuses isgoing to save you nor ar the right wing fascist Hindu gods. And you can't et all tht plastic and shit your dumping in oceans and waterways either.And even compters require rare elements and still run on fossil fuel just like our cars which are all chased upon eightennth centurt Enflish coakltechnolgy of burning fossil fuel to run steam engines to make metal move - i-e. pumps,railroads.steam driven ships,etc.Cars and computers also require
fossil fuel to make metal or autos move down the highway and computers require burning fossil fuels to generate electron flow.
Even when the Maya or Indus Valley or Tigris Euphrates Mesopotamian soil collapses occured abandonment allowed some slow regenertion of soil and their was still wild plant and animal populations to regenerate these biomes.Trees returned and climbed the old Mayan pyramids.Monkeys and jaguars etc. were not made extinct.But the fossil fuel Late Classic Idustrial Era is another beast and plant animal and insect speciesectinction are occuring on a massive acale and genetic diversity is itself becoming extinct.Even ocean ph is chanbing inpart due tofrom burning fossil carbon CO2 difusing into their waters.
Is the world headed for an ice apocalypse?
Rapid collapse of Antarctic glaciers could flood coastal cities by the end of this century.

In a remote region of Antarctica known as Pine Island Bay, 2,500 miles from the tip of South America, two glaciers hold human civilization hostage.
Stretching across a frozen plain more than 150 miles long, these glaciers, named Pine Island and Thwaites, have marched steadily for millennia toward the Amundsen Sea, part of the vast Southern Ocean. Further inland, the glaciers widen into a two-mile-thick reserve of ice covering an area the size of Texas.
There’s no doubt this ice will melt as the world warms. The vital question is when.
The glaciers of Pine Island Bay are two of the largest and fastest-melting in Antarctica. (A Rolling Stone feature earlier this year dubbed Thwaites “The Doomsday Glacier.”) Together, they act as a plug holding back enough ice to pour 11 feet of sea-level rise into the world’s oceans — an amount that would submerge every coastal city on the planet. For that reason, finding out how fast these glaciers will collapse is one of the most important scientific questions in the world today.
To figure that out, scientists have been looking back to the end of the last ice age, about 11,000 years ago, when global temperatures stood at roughly their current levels. The bad news? There’s growing evidence that the Pine Island Bay glaciers collapsed rapidly back then, flooding the world’s coastlines — partially the result of something called “marine ice-cliff instability.”
The ocean floor gets deeper toward the center of this part of Antarctica, so each new iceberg that breaks away exposes taller and taller cliffs. Ice gets so heavy that these taller cliffs can’t support their own weight. Once they start to crumble, the destruction would be unstoppable.
