extinct predators animals last 100 years

Mobile apps, GIS satellite data, and online crowdsourcing, Pimm says, may be a partial antidote to the problem.

(See: ' 20,000 Species Are Near Extinction: Is It Time to Rethink How We Decide Which to Save?') Study leader Stuart Pimm, a conservation ecologist at Duke University and contributor to National Geographic's News Watch blog, and his colleagues analyzed various data sources-in particular the International Union for Conservation of Nature's Red List of Threatened Species, a global inventory of species-to produce the first major review of extinction data. That's good news, because according to a review published on May 29 in the journal Science, current extinction rates are up to a thousand times higher than they would be if people weren't in the picture.

Now, according to a new review of research about Earth's biodiversity, it's giving conservationists hope that new technology can slow extinctions. This kind of citizen science has exploded in recent years because of smartphones.
