According to the WWF’s Living Planet Report 2020, it is estimated that natural biodiversity fell by 68 percent on average between 1970 and 2016. For the 56 percent of us who now inhabit urban areas, the natural world may seem distant and unconnected from our everyday lives. The truth is our existence relies on symbiosis with nature. Nearly half of the world’s population is directly reliant on natural resources for their livelihoods. The continued degradation of our ecosystem can only have negative consequences for humanity. Stopping and reversing this trend will not only take multilateral political action of the kind seen at COP26, but it will also require international scientific cooperation far beyond anything we have attempted.
