A new United Nations (UN) report says one-fifth of the world’s migratory (迁徙的) animals are at risk of disappearing. Animals that migrate move from one area to another at different times of the year.
The threats the animals face include habitat loss, illegal hunting, pollution and natural disasters. Many kinds of migratory animals, including songbirds, sea turtles, whales, sharks and others, move to different environments as the seasons change.
The UN report says about 44 percent of migratory species around the world are decreasing in population. In addition, about one in five of 1,200 species watched by the UN are at risk of becoming endangered, or completely disappearing.
These are species that move around the globe. They move to feed and breed and also need sites to stop along the way. Any habitat loss or other threats during their trips can make the animal populations fall. “Migration is important to some species. If you cut the migration, you’re going to kill the species,” said an expert.
The researchers examined existing data, including information from the International Union for Conservation of Nature’s Red List of Threatened Species. The list identifies wildlife across the world facing threats at present.
The report was presented at a meeting of the UN’s Convention on the Conservation of Migratory Species of Wild Animals in Samarkand, Uzbekistan. Attendees of the gathering are examining suggestions for conservation measures. They are also working to identify new species of concern. Susan Lieberman is vice president of the international policy at the Wildlife Conservation Society, a non-governmental organization. She said, “One country alone cannot save any of these species.”
The report found habitat loss affected up to 75 percent of the species studied. The report said this shows a big need for more connectivity between separated ecosystems. It pushes governments to take steps to avoid harming habitats and migration paths when building dams, pipelines or wind power equipment.
