The World Wildlife Fund considers sea lions an endangered species. This classification indicates that a species of animals has a high risk of total extinction in the wild. Conservation efforts concerned with endangered animals mostly focus on protecting natural habitats and limiting human interference.
Sea lion numbers struggle for a long list of reasons. Human intervention remains one of the largest issues facing the species to date. Hunting, killing or even interacting with the animals is illegal in many areas of the world, but some countries fail to enforce the guidelines effectively. Sea lions are also highly predisposed to illnesses such as pneumonia, cancer and epilepsy, each of which remains difficult for conservationists to catch and treat quickly.
