非洲130万头角马的迁徙受到人类发展的威胁，并导致了基因问题。 1.3 million wildebeest migration in Africa threatened by human development, leading to genetic issues.

非洲人类不断加速的发展，包括修建道路、围栏、农场和城市扩张，威胁着角马的迁徙，并导致了草原动物的基因问题。 Wildebeest migration is threatened by increasing human development in Africa, including roads, fences, farms and urban sprawl, leading to genetic issues for savannah animals. 每年有 130 万头角马穿越坦桑尼亚塞伦盖蒂和肯尼亚马赛马拉进行迁徙，这是生态系统的重要组成部分。然而，由于其历史迁徙路线被中断，迁徙正面临危险。 The iconic 1.3 million wildebeest migration through Tanzania's Serengeti and Kenya's Masai Mara, an essential part of ecosystem function, is at risk due to disruptions to their historic migratory routes. 由于角马无法再四处游荡，它们的基因变得越来越弱，新的研究表明，这是一个日益严重的问题。 As wildebeest can no longer roam far and wide, they are becoming genetically weaker, with new research suggesting that this is a growing problem.
