might be taken. The Intergovernmental Panel on Climate Change has identified
four basic systems for capturing CO
2
from use of fossil fuels and/or biomass
processes:
1. Capture from industrial process streams
2. Postcombustion capture
3. Oxyfuel combustion capture
4. Precombustion capture.

The probable critical paths of these technologies are shown in Figure 7.12.
Thus, there are numerous ways of conserving and adding to natural sequestration
processes that could significantly decrease the net greenhouse gas concentrations
in the atmosphere.
THE GOOD, THE BAD, AND THE MISUNDERSTOOD
All life on Earth consists of molecules that contain carbon. Carbon is part of
every essential process that sustains life, including photosynthesis, respiration, and
biodegradation. It is absurd to label carbon “good” or “bad” since its utility and
harm are clearly dependent on time and place.
