Fishes in the desert: paradox and responsibility
An adequate ethic for the conservation of desert fishes requires an unprecedented mixture of biology and ethics. Anthropocentric rationales based on benefits to humans are insufficient.

Human have duties not simply to other humans but to species of fish--instance, increment, and symbol of respect for life on Earth.
