If you want to know where you would have stood on slavery before the Civil War, dont look at where you stand on slavery today. Look at where you stand on animal rights. Paul Watson.
The following is a document archive for the native fish of the Colorado River, which have the highest rate of jeopardy toward extinction in the nation. Read article here.
Historically, the native fish fauna of the Colorado River Basin was dominated by the minnow (cyprinids) and sucker (catostomids) families. Of the 34 known native species to the Colorado River basin, 74% are found nowhere else in the world, or endemic.
Threats to these species include streamflow regulation and habitat modification, altered food web, predation by nonnative fish species, parasitism, hybridization with other native fish species, and pesticides, toxins and pollutants. These changes to the river environment have occurred so quickly that the species have been unable to a adapt, so pro-active human intervention is the only hope they have. Since the river is truncated by 83 dams in the upper basin and 10 dams in the lower basin, this loss of genetic diversity will also impede their recovery.
