The Price of Biodiversity
Biodiversity - the species we share our planet with - is under pressure. Post-2015 Consensus research finds that a global target to prevent the loss of coral reefs will gives at least $24 of environmental benefits per dollar spent. Likewise, reducing the current loss of forests by half would likely do about $10 of good for each dollar spent. However, increasing protected areas, because it is very costly but only somewhat helpful, is likely to do less than $1 of good per dollar spent.
