Earth lost 50% of its wildlife in the past 40 years, says WWF

The number of wild animals on Earth has halved in the past 40 years, according to a new analysis.

Even if one doubts the messengers, their methodology, or their numbers, it cannot be denied that man is having a demonstrable impact on the sustainability of other species. One need only be aware of the occasional, but growing more frequent, news reports of the decline of specific species. The 50% figure may not be accurate. What if it's 40%, 30%. 25%? What comfort should the smaller number bring us? It may be time for alarm. It is certainly time for concern.
