Actually it's guesswork WITH facts
#9 zackers,
I have lived on a farm in Kansas most of my life as well, and as
you well know, the key to both healthy humans and farm animals
are the sanitation practices used. Most diseases in human history
have been alleviated through cultural practices, and this still will
be the case with or without climate change. That doesn't mean
that some pretty nasty tropical diseases can't shift their ranges
northward as the climate continues to change, necessitating new
programs to fight their spread, all of which cost money. There's
certainly no harm trying to project where these might be needed
and plan accordingly, any more than trying to prevent mad cow
disease from spreading on ranches, something that has no
connection to climate change.
Not sure what your point is about food production. Sure, shifting
climate patterns will mean better growing conditions to the north,
but living in Kansas, I'm sure as heck concerned about what it will
do for my area, aren't you? Seed companies are already
producing new varieties, but guess what? Lots more money--
surprise, surprise!
