“如果我们不去认识这些千古的灭绝过程,我们就无法去抗衡未来更多的物种灭绝事件。” 动物化石,不只是冰冷的遗骸,更是解开生命谜题的钥匙。 二十多年来,林泽昇追寻跨越八千万年的痕迹,从婆罗洲亚洲象的牙齿残片,到黑风洞红毛猩猩的化石,每一次发现,都让我们更接近真相:谁在这里生活过?他们为何又消失?埋藏在化石里的答案,揭示了远古人类与环境如何一步步塑造出今日的生态面貌。 认识过去,才能守护现在。那些看似 “灭绝的故事”,其实正提醒我们:保护濒危物种,不只是科学的课题,更是你我共同的责任。 “If we fail to understand these mass extinction events from the past, we won't be able to prevent those in the future.” More than cold and lifeless remains, fossils are the keys to unlocking the mysteries of life. For over twenty years Lim Tze Tshen has searched for tr ...

Core Viewpoint - An international research team has reported that nearly 8,000 species of mammals, birds, reptiles, and amphibians may face extinction risks by the end of the century due to climate change and human activities [1] Group 1: Research Findings - The study analyzed the survival status of nearly 30,000 species, focusing on their preferred habitat environments, temperature tolerances, and predictions for climate and land use changes in the 21st century [1] - The research indicates that by the end of the century, approximately 8,000 species will encounter unsuitable living conditions, primarily due to extreme heat caused by climate change and habitat loss from human activities [1] Group 2: Affected Regions - The Sahel region of Africa, large areas of Brazil, and parts of the Middle East are identified as particularly severely affected by these changes [1] - The potential decline in species diversity and the destruction of ecosystems could have serious implications for human living environments [1] Group 3: Call to Action - Researchers emphasize the need for global action to enhance environmental and natural protection to maintain biodiversity [1]
