O valor da biodiversidade

We could go far towards safeguarding the hotspots and thus a large proportion of all species at risk for an average of $20 million per hotspot per year over the next five years, or $500 million annually. Although this is 12.5 times the annual average of the $400 million spent on hotspots over the past decade, it is still only twice the cost of a single Pathfinder mission to Mars, which has been justified largely on biodiversity grounds (the search for extraterrestrial life).
