We discuss and comment on the role agriculture will play in the containment of the CO2 problem and address protocols for terraforming the planet Earth.
A model farm template is imagined as the central methodology. A broad range of timely science news and other topics of interest are commented on.

This is the first intact mastodon
skull found in Chile.Yet it is a reminder that the genus made it
not just into North America, but also into South America.
The extinction of large animals
in the Northern Hemisphere can be explained by the event that I have named the
Pleistocene nonconformity which initially decimated the extant
populations.We can easily surmise that
the remainder was hunted out by early man who had the tools.The problem I have with all that is the
African Elephant particularly.It never
was successfully hunted by well equipped local tribesmen before the advent of
That it could be hunted is
irrelevant, it simply never was properly exploited.Thus I find the human agency theory for both Americas
uncomfortable, just as the Pleistocene Nonconformity also failed to actually
eliminate all individuals.And the
argument of habitat change simply does not fly with a mastodon that eats brush.
As this item reminds us, this
creature was able to populate every valley on earth at will, and only a handful
ever pulled that feat off.
On top of that the mastodon was a
forest dweller, quite able to protect itself.Recall that no one in his right mind is going to sneak up on an elephant
in the woods and stick a spear into its gut.There is plenty of easier ways to make a meal.
They almost certainly would have
been trapped in a pit at the least.They
were also likely too clever to run over a cliff or even be stampeded. Certainly, African elephant do not look
likely to ever stampede, unless it is over their tormentors.
The fact remains that the genus
is incredibly successful.Yet we have
huge extinction events that can not be properly explained.Even the Indian Elephant avoided extinction
and it was exposed to some of the worse land disturbances if we accept the consequences
of the Nonconformity.In fact all
obvious threats are just as obviously survivable.These creatures were never thin on the ground
and vulnerable to over hunting at all.Besides, you would only learn to hunt them if they were common enough to
make it worthwhile.Even in Africa, that turned out to be an unattractive
On top of that, the end of the
Ice Age would have naturally expanded their range and they would have easily
adapted to warmer conditions.
One other option that does work
is that they were deliberately hunted out by an ancestral human stock with
access to modern tools.We could today
choose to eliminate all elephants quite easily and could also reduce or
eliminate a few other inconvenient large creatures.I prefer not to use that option, except that
the genus was just too successful globally to simply disappear easily.
