After the 2nd law of thermodynamics, 90% of
the available energy in any trophic level is not
transferred to the next trophic level. Thus, the
total amount of energy available to animals that are at the top of the trophic pyramid is very low. Therefore, there is not enough
available energy to sustain large populations of top predators.
4) CCD or
CCSÉ
Carbon Capture and Disposal/Sequestration. There are many possible problems,
such as: how long the carbon will remain sequestered, leakage and contamination
of ground water, cost of capture technology, cost of storage, etc.
