Ozone Depletion Questions:

Question #1:

How was "The Limits to Growth" supposedly discredited ?

Back in the 1970's the aggregation "The Limits to Growth" said, basically, that if we didn't advise to a sustainable frugalness "soon" we would be royally screwed by 2100. The base premise of the model is too ultimate to debate with - the planet has exclusive so such land, and with continued exponential ontogeny it module all be sealed over with no room mitt for farms, at which point we every decease - or rather sooner than that.

In the intervening instance we hit somehow pretended the problems don't exist, yet separate into ozone depletion, orbicular warming, PCB accumulation and habitat destruction. The models still give the same answers - if we continue business as usual, we will be royally screwed by 2100 - back to 1900's levels of population and income, but with no easy resources mitt to exploit.

So what happened ?
