Nowadays there are numerous environmental problems in the world, and one of the biggest issues is animal extinction. Habitat issues, poachers, and climate have a huge effect on them. People are searching for solutions and already found some, like informing society with red books, social media, or creating reserves for them.For instance -The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. There are several national and international organizations that oversee the numerous non-profit animal sanctuaries and refuges to provide a general system for sanctuaries to follow. Among them, the American Sanctuary Association monitors and aids in various facilities to care for exotic wildlife.[8] The number of sanctuaries has substantially increased over the past few years.
