Lake Baikal in eastern Siberia is the deepest and (by volume) largest lake on Earth. Among the most ancient lakes, it is home to thousands of endemic species. Lake Baikal is well-known for its water purity, especially its dominant deep-water layers, which consist of pristine, drinking-quality water and is inhabited by unique endemics with enormous biodiversity. But some coastal sites of this giant lake (mainly localized in isolated shallow bays and littoral zones close to settlements and industrial sites) are suffering from an environmental crisis that threatens the water's quality and the ecosystem it supports. As part of the global ecosystem, Lake Baikal is already facing significant impacts from global climate change, which, in turn, increase the risks and consequences of local anthropogenic effects. Although the lake is protected by federal law, human activities are nevertheless having a growing negative impact on its ecosystem. Political, economic, and social factors result in cascading natural consequences in water quality, coastal sustainability, pollution sinks, water level management, forest maintenance, fire control and biodiversity. While Lake Baikal is a UNESCO World Heritage Site, known and valued around the world, it remains vulnerable to worsening threats that must be addressed if humanity is to preserve this unique ecosystem and its endemic species into the future.

贝加尔湖的人类影响和生态系统健康

西伯利亚东部的贝加尔湖是地球上最深和（按体积计算）最大的湖泊。在最古老的湖泊中，它是数千种特有物种的家园。贝加尔湖以其水质纯净而闻名，尤其是其占主导地位的深水层，这些水层由纯净的饮用水组成，并且栖息着具有巨大生物多样性的独特地方性物种。但是这个巨大湖泊的一些沿海地区（主要位于孤立的浅海湾和靠近定居点和工业区的沿海地区）正在遭受环境危机，威胁到水的质量和它所支持的生态系统。作为全球生态系统的一部分，贝加尔湖已经面临全球气候变化的重大影响，这反过来又增加了当地人为影响的风险和后果。尽管该湖受到联邦法律的保护，但人类活动对其生态系统产生了越来越大的负面影响。政治、经济和社会因素对水质、沿海可持续性、污染汇、水位管理、森林维护、消防和生物多样性造成了一系列自然后果。虽然贝加尔湖是联合国教科文组织世界遗产，在世界范围内广为人知并受到重视，但如果人类要在未来保护这个独特的生态系统及其特有物种，就必须解决这些日益恶化的威胁。森林维护、防火和生物多样性。虽然贝加尔湖是联合国教科文组织世界遗产，在世界范围内广为人知并受到重视，但如果人类要在未来保护这个独特的生态系统及其特有物种，就必须解决这些日益恶化的威胁。森林维护、防火和生物多样性。虽然贝加尔湖是联合国教科文组织世界遗产，在世界范围内广为人知并受到重视，但如果人类要在未来保护这个独特的生态系统及其特有物种，就必须解决这些日益恶化的威胁。
