The condoms, which debuted last year, feature six different endangered species. With the help of intrepid volunteers, the Center for Biological Diversity gave away 350,000 of them in 2010.

The largest cat in North America, the jaguar formerly roamed the borderlands of California, Arizona, New Mexico, and Texas. It disappeared as human settlements spread further and further into its wilderness habitat. The U.S. population of jaguars was put on the endangered species list in 1997.

The Puerto Rico rock frog, also known as the coquí guajón, lives in caves, grottos, and streamsides in southeast Puerto Rico. It was put on the endangered species list in 1997 due to destruction of its habitat by urban sprawl, roads, garbage dumping, deforestation, and pesticide poisoning.

The snail darter lives in just nine populations in the Tennessee River drainage in eastern Tennessee. Its habitat has been severely reduced by dams constructed to provide water, power, and barge transportation to a rapidly growing human population. It was put on the endangered species list in 1975.

The spotted owl depends on old-growth forests, which are being cut down to supply timber, wood fiber, and toilet paper to an ever-growing human population. It was put on the endangered species list in the Northwest in 1990 and the Southwest in 1993.

The large, spectacularly colored American burying beetle has disappeared from more than 90 percent of its former range due to disruption of its food chain by humans, including the human-caused decline of top predators like wolves and bears and carrion species such as passenger pigeons. The beetle was put on the endangered species list in 1989.

The international icon of global warming, the polar bear is going extinct as the Arctic sea ice melts beneath its feet due to the greenhouse gas emissions of the world's 7 billion people, especially those in high-consumption nations like the United States. The bear was put on the endangered species list in 2008.
