An environmental group that fights to protect endangered species plans to distribute 100,000 free condoms across the US beginning on Valentine's Day. The Center for Biological Diversity in Tucson says the promotion is meant to call attention to the impact of human overpopulation on endangered species.

The group will hand out six different condom packages with original artwork. Slogans on the packages include "Wrap with care, save the polar bear," and "Wear a condom now, save the spotted owl." The centre's Randy Serraglio says human overpopulation is destroying wildlife habitat at an unprecedented rate.

The endangered species condoms will be distributed in bars, supermarkets, schools, concerts, parties, and other public events.
