Re: [xmca] Human footprint too big for nature

Gee, I thought this was going to be about the discovery of BigFoot!

And in a way, I guess it is, with the
too-big-for-our-shoes resource greed of the
overdeveloped countries (led no doubt by my own)
marching profitably toward disaster.

I am comforted that I probably won't make it to
2050, miracles of modern (also resource
profligate) medicine, notwithstanding. On the
other hand, when I taught Environment Science at
the university in New York for a few years in the
1970s, the extrapolations from then current data
all indicated to me that the first signs of
global eco-tastrophe would be showing up around
2020. Extrapolations are tricky in these matters
because of all the feedback loops, which
generally tend to make problems come sooner and
be worse than expected. (If you are not prone to
nightmares, or eco-anxiety, have a look at
Holling & Gunderson, 2002, _Panarchy_, or under
Thresholds. These people are among the leading
ecosystem theorists and researchers in the world.)

Do juggernauts ever have second thoughts?
