[Coral-List] More positive outlook would be nice but...

I am delighted to see Alina back and apparently unmellowed by time or

She is correct in her analyses and conclusions.  Whether you agree with her
or not, consider risk evaluation -- assessment of the penalties for being
wrong in policy or action.

Assume that climate change and/or overpopulation are serious and
potentially catastrophic problems.  Get that wrong and act on it, and you
may suffer major unnecessary expenses and hardship.  Assume no problem, and
error may result in a real possibility of extinction (ours, as well as that
of our beloved invertebrates).  Go ahead, decide what you value and what
chances you are willing to take. Then pick one of the choices.

Although I fundamentally agree with Alina, I have a tactical disagreement
with her.  I think attacking climate change first is the most practical
course. The evidence mounts rapidly, more and more people are taking it
seriously, there are some feasible actions that can be taken -- and serious
attention leads inexorably to consideration of the overpopulation problem.
As long as people are comforted by the prospect of an empty planet, or
arguing that the issue merits more nuanced discussion, we are very far away
from addressing in any useful fashion whatever population problem there
might be.

Pessimistically yours,

Bob Buddemeier
