On February 12th, the UN released its firstever report on migratory species. It indicated that nearly half (44%) of migratory species on Earth are in rapid decline. More than a fifth of the nearly 1,200 species monitored by the UN are threatened with extinction.
 　Many songbirds, fish, sea turtles, whales, sharks and other migratory animals move around the globe every year. They travel by land, the oceans and the sky.
 　But now their migration is being cut and population is shrinking at a shocking rate. Most worryingly, nearly all (97%) of the listed fish species are facing a high risk of extinction.
 　What are the largest threats to all migratory species? Overexploitation and habitat loss due to human activity. Climate change is also listed as a threat to the animals, as are pollution and invasive species.
 　Migrating animals are vital to the health of ecosystems worldwide. Population recovery is possible. One of the key priorities is international cooperation as migratory animals’ survival depends on the efforts of all countries in which they are found.

　聯合國2 月12日公布有史以來第一份關於遷徙物種狀況的報告。報告指出，地球上近一半（44%）的遷徙動物正在迅速減少；聯合國監測的近1200 個物種中，有超過五分之一面臨絕種威脅。
　許多鳴禽、魚類、海龜、鯨魚、鯊魚等遷徙動物，每年遷移到世界不同的角落。牠們經由陸地、海洋或空中遷徙到另外一個棲息地。
　但如今，牠們的遷徙受到阻礙，物種存活數量正以驚人的速度削減。最令人擔憂的是，高達97%列入監測名單的魚類物種，都面臨絕種的高度風險。
　遷徙物種面臨的最大威脅是什麼？人類活動與過度開發，導致棲息地喪失。此外，氣候變遷、汙染和外來物種入侵也造成對動物的威脅。
　遷徙物種對全球生態系統的健康至關重要。恢復這些物種的數量仍是可能的。國際合作是關鍵優先要務之一，因為遷徙動物的生存有賴於牠們所在的國家共同努力。
