Conservation Over the past century, rapid growth in human populations and their resource consumption levels have put increasing pressure on the natural world. In a Perspective, Ellis explains that efforts to make the world a fairer place for both human populations and the rest of nature are already under way. To build on these efforts, human societies will need to leverage economies of scale by making cities denser and agriculture more productive. At the same time, increased conservation efforts must be implemented in such a way as to benefit people as well as the wider natural world. Science , this issue p.
