On this Halloween, The Center for Biological Diversity distributed 6,000 endangered species condoms across six states in the United States. Since the past nine years, the centre has been using similar popular occasions to make people aware of the declining wildlife. Drawing parallels between the increasing human population and reducing forest, the centre gives out free condoms featuring endangered species.

These condom packs feature caricatures of endangered animals along with a quirky line on why you should use it.  These creative captions are quite eye-catchy and can make anyone giggle. One of their innovative captions read: 'Cover your tweedle...save the burying beetle' while other with the picture of a bear reads: 'Wrap with care...save the polar bear'. Another one reads: 'Don't go bare...panthers are rare'. 60 Percent of Earth's Wildlife Has Been Lost, We Are the 'Last Generation' That Can Save Nature, Says WWF.

The uncontrolled population is one of the main reasons for the dwindling biodiversity, especially among wildlife. According to the World Wildlife Fund (WWF), the animal population has seen a 60 percent decline in the past forty years. As per the Living Planet Report 2018, more than 4000 mammals, birds, fish, reptiles and amphibian species have declined between 1970 and 2014. According to the report, the species extinction is now 100 times higher than before humans involved in animal ecosystems.
