Mankind displays (collectively) the mentality of a two year old child
(perhaps I overestimate).

Perhaps someday (if we survive long enough) we will grow up and become an
adult species.

Not a good idea.

These turtles slow metabolic rate and omnivorous diet can render their
flesh poisonous to humans. Accounts specific to the dangers of eating box
turtles include a report that Pennsylvania miners ate box turtles (during a
strike) and became ill. This account explains that the turtles may had fed
on a poisonous fungus, which did not affect them but made their flesh
temporarily poisonous (Ernst 1972). Another account tells of box turtles
that were accidentally roasted in burning brushpiles in Mississippi and
were eaten by several boys, all of whom subsequently became ill (Carr
1952).

Unfortunately they are not accessable for use as fuels.

there is not nearly enough fossil fuel to account for the atmospheric
oxygen inventory. But there is a lot more organic matter buried in the
crust in the form of finely disseminated particles incorporated in shales
and limestones.

Actually if ALL the reduced carbon were burned, it would take more oxygen
than is available.

"Clearly, there is more organic matter in the crust than can be accounted
for only by the amount of oxygen in the air and in these oxidized
reservoirs. The additional organic matter must have come from anaerobic
bacteria that converted carbon dioxide to organics via processes that do
not create free oxygen. (These bacteria use reduced chemical species from
weathered igneous rocks and from emanations of volcanic/hydrothermal gases
and fluids.)
[unquote]

As I said before, much of the CO2 removed from the atmosphere was turned
into things like calcium carbonate and other minerals.
[quote]
"Organic matter in shales is the dominant reduced carbon reservoir. The
earth's crust contains 1.1 x 1021 moles of reduced carbon--that is, carbon
that has been freed from its oxygen (one mole of an element is equal to
6.02 x 1023 atoms of that substance). The total amount of organic carbon
needed to account for all the oxygen in the atmosphere is only 0.038 x 1021
moles! In other words, based on the amount of buried carbon, the atmosphere
seems to contain far too little oxygen. Some of that missing oxygen has
gone into other materials, 'oxidizing' them in the process. Oxidized
reservoirs whose oxygen probably derives from organic matter are sulfate,
found in both seawater and evaporite rocks (equivalent to 0.48 x 1021 moles
of organics) and in ferric iron (equivalent to 0.064 x 1021 moles).

Just to keep things straight, the O2 in the air comes from Water, not from
CO2.

[quote from http://www.biologie.uni-hamburg.de/b-online/e24/24.htm]
.....photosynthesis [is] a redox reaction with H2X as the electron donator
(the oxydizable substance). In the case of green plants is it H2O and this
means that not the carbon dioxide but the water is broken down.
[unquote]


Thus, the oxygen in the air comes mostly from breakdown of WATER. Of
course, that breakdown also produces hydrogen and the plants use CO2 to get
Carbon and make hydrocarbons, but plants can produce oxygen without CO2.
