50 years. In a research paper on biodiversity for Copenhagen Consensus 2012, Salman Hussain and Anil Markandya find that there will be a significant loss of biodiversity over the next 40 years. They estimate that this loss could be about 12 percent globally, with South Asia facing a loss of 30 percent and sub-Saharan Africa 18 percent. They look at three interventions and compare these to doing nothing.
