Biologists and conservation experts are warning that the natural world faces some serious challenges in the near future due to human activity, according to pair of new reports.
Although there have been some recent reports of conservation successes, particularly with tiger and elephant populations, wildlife in general is "in freefall," according to the World Wildlife Fund. By 2100, the world could look much, much different, with hundreds of mammal species currently at risk and a "second wave of extinctions" on the horizon.
