A place in time when all economic structures cease to function, according to the 502nd law of thermoeconomics:
All economic systems tend towards ever greater accumulation of increasingly insubstantial pseudo-scientific jargon; a stake of play that will ultimately result in the violent collapse and subsequent explosion of the econoverse in a molten halo of flaming bullshit.
(n) The legendary end of the world as prophesied in the theological teachings of the First Church of the Environment (Fundamentalist) by Envirofundamentalists. The most common vision of the ecopocalypse involves the global climate passing a "tipping point" and the Earth turning into a burnt-out hulk no longer able to support life. Other variations on this theme include all the Earth's glaciers melting and turning Earth into Waterworld, and a global-warming induced ice age.
Repent! For the ecopocalypse is upon us in 10 years.... and it'll always be upon us in 10 years.
