Short summary
It is not only the climate that is changing. We are now also observing a global biological change. Here we revise the overwhelming evidence that these changes affect not only individual species but also simplify the structure of entire food webs, threatening long-term community persistence. We must take urgent action to protect the integrity of natural food webs, or we might rapidly push entire ecosystems outside their safe zones.
