Sustainable use is one of the three objectives of the Convention on Biological Diversity: "sustainable use means the use of components of biological diversity in a way and at a rate that does not lead to the long-term decline of biological diversity, thereby maintaining its potential to meet the needs and aspirations of present and future generations" -- http://www.biodiv.org/programmes/socio-eco/use/
. Inevitably there are many nuances of interpretation, especially of "needs and aspirations".
