The Guardian last week published an article by George Monbiot and Guillaume Chapron, a researcher at the Swedish University of Agricultural Sciences, calling for readers to nominate key actions which can make a significant difference to halting biodiversity loss worldwide. The authors are seeking actions which ‘make a major contribution to protecting a particular species or ecosystem and that are ‘strongly and widely supported by scientific evidence published in academic journals; but that are politically costly or opposed by special interest groups.’

Submit ideas to the Biodiversity100 campaign or see what others have suggested at the Guardian website. Readers have been given one month to submit their ideas, before the final list of 100 tasks, for presentation to G20 governments, is decided.
