Very sad news.
British broadcaster and naturalist Sir David Attenborough once asked: "Are we happy to suppose that our grandchildren may never be able to see an elephant except in a picture book?"
2014 marked the 100th anniversary of the death of the last passenger pigeon, Martha, who managed to survive only 14 years in captivity after her species became extinct in the wild. More recently, Angalifu, a 44-year-old northern white rhinoceros, died at the San Diego Zoo, leaving just five other white rhinos worldwide, all in captivity. Chances are our grandchildren will never get to see this remarkable creature.
In fact, the world is losing dozens of species every day in what experts are calling the sixth mass extinction in Earth's history. As many as 30% to 50% of all species are moving toward extinction by mid-century — and the blame sits squarely on our shoulders.
