1) SustainabilityÉ

 

            Use of resources that does not compromise the use of those resources in the future.

 

2) EmissionsÉ

 

            Regulate the private sector because energy consumption by homes and personal transportation has increased far more in the last twenty years than has use of energy by industry.

 

3) Big, fierce animalsÉ

 

            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.
