|In summary, we
may need to control greenhouse gases if human development is to be sustained.
|The carbon cycle
provides insight as to how it is done. Humans can help.
|We’ve touched on
just a few examples. Some of them are close to practical reality now. Others
are closer to science fiction than to engineered solutions. Much research is
needed to establish the science to evaluate and develop hypothetical
solutions. Much ingenuity and effort will be needed to establish the
infrastructure to apply them.
development of science and the application of engineering principles can
establish more intelligent human intervention with the carbon cycle.
