This article explains why. Here are two brief exerts:

"For all of WWF’s hyperbole about “humanity’s destruction of nature,” the decline of wildlife is nowhere near “catastrophic.” Back in 2007, we were told polar bears would be extinct by 2030, and the same groups and media outlets were up in arms about its demise; in fact, their numbers are abundant."

"Finally, it’s worth noting just what a small snapshot this report is looking at. The Living Planet Index is “currently based on time-series data for 20,811 populations of 4,392 species of mammals, birds, reptiles, amphibians and fish from around the globe.” That is an impressive body of material. But there are around 66,000 different species of vertebrate, so the Index is just a fairly small sample of the wider picture."
