William,
I think the silly thing Mixon was talking about is the
little date and clock display that follows the cursor around.

Mixon,
Don't be too negative about the Indians, their English
isn't the best but they are trying to do good, and that should be
rewarded. Besides, they have some useful concepts. In the section
on Kotumsar Cave they introduce the idea of "anthropogenic
pressure." Anthropogenic pressure is reducing the
biodiversity. This term should replace carrying capacity as it
sounds more serious and much more scientific. We in Texas could
work with this idea, and make it even better. First we need units
so we can measure the anthropogenic pressure. Let us define one
Mixon as the pressure [impact] produced by one person visiting the
cave and acting on one sq. m of the cave footprint each
year. Anthropogenic pressure has units of people/year/sq
meter. We can evaluate Texas caves and see what we find. We might
find that caves over, say 5 Mixons are environmentally hopeless and
might as well be abandoned.
