Seeing Is Believing ...........

Isolated for 42 days in chambers of ambient
and elevated CO2 concentrations, they periodically documented the
growth of cowpea plants (Vigna unguiculata) via time-lapse photography
with quite impressive results indeed...............Carbon dioxide is
good for the environment.
The simple fact must be restated to counter environmentalists'
baseless allegations that the accumulation of man-made carbon dioxide,
produced by cars, power plants and other human activities, is causing
dangerous global warming. Indeed, far from being a poisonous gas that
will wreak havoc on the planet's ecosystem, carbon dioxide is arguably
the Earth's best friend in that trees, wheat, peanuts, flowers, cotton
and numerous other plants significantly benefit from increased levels
of atmospheric carbon dioxide. Increased atmospheric carbon dioxide
doesn't just make a plant bigger. Carbon dioxide also makes plants
more resistant to extreme weather conditions. Bigger trees, increased
resistance to bad weather, improved agricultural productivity and a
boon to rainforests are just some of the many benefits that carbon
dioxide bestows on the environment. With little evidence that carbon
dioxide triggers dangerous global warming but lots of evidence showing
how carbon dioxide helps the environment, environmentalists should be extolling the virtues of this benign greenhouse gas.
