Endangered delta smelt are increasingly rare in the wild. The fish shown here were hatched at the UC Davis Fish Conservation and Culture Laboratory.
Worldwide, the U.N. assessment found that of an estimated 8 million plant and animal species, about 1 million are on the brink of extinction because of the damage humans are inflicting on the Earth through global warming, logging, farming, mining and other activities. It was compiled by 145 expert authors from 50 countries.
The numbers were so stark, and so unlike what scientists were seeing in the rest of the state, Beissinger and his doctoral students began to wonder whether climate change had made an already extreme environment almost uninhabitable. Other species are not arriving to replace those that are gone. So far, there appears to be only one type of bird whose numbers are increasing in the Mojave: the common raven.Delta smelt are an endangered species caught in a battle between environmentalists trying to save them and farmers who dismiss such efforts as prioritizing fish over people.First listed as endangered in 1993, the species is now on the verge of extinction.
“We have economic factors driving things and we’re not necessarily paying attention to the consequences,” he said.As humans continue to alter the Earth for their benefit, not all animals are experiencing the changes equally. The authors of the U.N. report single out amphibian species, writing that more than 40% of them are threatened and could disappear if loss of habitat and threats from invasive species continue.is an example of this trend.
