A common rebuttal to skeptics of global warming, when they hear scientific
proof such as this, goes something like this: Humans are capable of moving
between areas with clean air and dirty air with little problem. Fish can do
likewise. If only it were that simple!
The truth is that people have adaptable pulmonary capabilities because we
have needed them for a very long time. Many of the aquatic species which
comprise the foundation of the food chain of our oceans have changed little or
not at all during the aforementioned 55 million years. When they are exposed to
large swings in their environment, they die.
Why haven’t they changed? Because they have had no exposure to changes in the
atmosphere! They live deep underwater, miles below the surface. Dr. Andy
Ridgwell of the University of Bristol explains the problem very well.
“Unlike surface plankton dwelling in a variable habitat, organisms living
deep down on the ocean floor are adapted to much more stable conditions. A rapid
and severe geochemical change in their environment would make their survival

In closing, if ever you have wondered why I advocate so vigorously for all of
us to live carbon-neutral, now you know. We are creating a crisis of even
greater magnitude than the planet did to itself during periods of massive
geological instability. For that, there can be no apology, merely remediation.
