研究结果显示,到本世纪末,预计将有近8000种物种面临不适宜的生存条件,包括气候变化导致的极端 高温以及人类活动导致的栖息地丧失。 以色列内盖夫本-古里安大学、英国牛津大学等机构的研究人员在学术期刊《全球变化生物学》上报告 说,城市化、农业扩张等土地利用方式变化以及其他人类活动,正在破坏动物的自然栖息地,并可能引 发大规模物种灭绝。 研究人员对近3万种哺乳动物、鸟类、爬行动物和两栖动物的生存状况进行了分析,研究了它们偏好的 栖息地环境、可承受的温度范围,以及21世纪气候变化和土地利用变化的预测情况。 新华社耶路撒冷12月18日电(记者王卓伦 冯国芮)一个国际团队日前发布的研究显示,由于气候变化 引发极端高温、人类活动挤压栖息地,到本世纪末,近8000种哺乳动物、鸟类、爬行动物和两栖动物可 能面临灭绝风险。 研究指出,非洲萨赫勒地区、巴西大片区域以及中东部分地区受影响尤为严重。地球未来可能面临物种 多样性大幅下降、生态系统遭受破坏的局面,这将对人类生存环境造成严重影响。研究人员希望采取全 球行动加强环境和自然保护,以维护生物多样性。(完) ...
