koala

澳大利亚东部和东南部的标志性有袋类动物，体重最大可达15千克，为了节省低热量桉树叶食物所提供的能量，每天最多睡眠22小时。高度特化，能够处理会致大多数其他哺乳动物死亡的有毒桉树成分，拥有专门适应解毒功能的肠道微生物群。因衣原体病、栖息地开发和气候变化导致种群锐减，2022年被列为濒危物种。

Rice

水稻（Oryza sativa）是人类历史上最重要的粮食作物，养活了全球超过一半的人口，是亚洲、非洲和拉丁美洲的主食谷物。约9,000年前在中国长江流域从野生稻（Oryza rufipogon）驯化而来，水稻种植塑造了文明、景观和生态系统。淹水稻田耕作为候鸟、两栖动物和水生无脊椎动物创造了广泛的湿地生境，同时也产生大量甲烷排放。
