Of course, the disaster of not enough carbon dioxide can be avoided if we all think ahead.
The current trend away from burning of waste products and fossil fuels could be reversed. More
people could purchase SUVs and Hummers. This would provide a valuable source of carbon dioxide in
the atmosphere.
If we continue in our unthinking direction of eliminating sources of carbon dioxide, by 2050 the
situation might become desperate. We might have to open up old oil wells and set them ablaze. We
could also strip the earth over coal deposits and light them afire to add desperately needed carbon
dioxide to the atmosphere. By these techniques, the ecological disaster can be avoided.
On the other hand, we might avoid all of these problems by manufacturing internal combustion
automobiles for all the people of the earth and by scrapping plans to use hydrogen powered cars. We
also might increase the burning of scrubbed coal to generate our electricity. The rate of burning
fossil fuels might not grow at the rate of consumption by desktop manufacturing units, but it might
be enough to postpone catastrophe into the 22nd century. By then, we will probably come up with
another solution.
