Mountain lion use of elevation ranges ([chi square] = 0.002, df = 2, P = 0.9991), ecological systems ([chi square] = 9.354, df = 4, P = 0.0528), and fine-scale terrain ruggedness classes ([chi square] = 1.622, df = 4, P = 0.8047) did not differ significantly from availability.
Today, the greenhouse gases and damage to forests and other ecological systems that naturally sequester carbon generated by the economy's massive throughput of energy and materials has destabilized our planet's climate.
Common and Stagl state that environmental economics concerns itself with the economy's insertions into the environment, and with problems of environmental pollution: ecological economics is about the interactions between economic systems and ecological systems, (12) treating individual preferences neither as sovereign, nor as the only source of normative criteria (there can be an ethical basis for comparing, evaluating and seeking to change tastes).

If the system is mapped using only ecological characteristics, then managers may not account for human responses to change, such as changing decisions about whether or how much to fish as fishing quality changes.
