Nature is under siege. In the last 10,000 y the human population has grown from 1 million to 7.8 billion. Much of Earth’s arable lands are already in agriculture (1), millions of acres of tropical forest are cleared each year (2, 3), atmospheric CO₂ levels are at their highest concentrations in more than 3 million y (4), and climates are erratically and steadily changing from pole to pole, triggering unprecedented droughts, fires, and floods across continents. Indeed, most biologists agree that the world has entered its sixth mass extinction event, the first since the end of the Cretaceous Period 66 million y ago, when more than 80% of all species, including the nonavian dinosaurs, perished.

人类世间的昆虫减少：一千次死亡[生物科学]

大自然在被包围。在过去的10,000年中，人口从100万增长到78亿。大部分地球的耕地面积已经成为农业（1），数以百万计的热带英亩森林被清除每年（2，3），大气中的二氧化碳₂水平在3万元以上Ÿ其最高浓度（4），和气候在各个极点之间不稳定且稳定地变化，引发了各大洲前所未有的干旱，大火和洪水。确实，大多数生物学家都同意，世界已经进入了第六次大规模灭绝事件，这是自白垩纪6600万年前结束以来的第一次灭绝事件，当时包括非禽类恐龙在内的所有物种中有80％以上灭绝了。
