Needless killing of endangered species for trophies is inherently unsustainable, economically short-sighted, ecologically unsound, and morally wrong. The sooner it ends for lions and other imperiled animals, the better.
Recently, African lions took one step closer to receiving much-needed protections from trophy hunters still eager to kill them despite their dwindling numbers. Of even greater importance is the fact that this announcement opens the door for everyone who loves big cats to take action.
Because the world's most imperiled species are sometimes found in the world's most dangerous places, the combustible mix of focused altruism and local desperation can collide and result in horrific tragedy.
The birth of this baby Sumatran rhino is hopefully just the first of more to come -- injecting new genes, new life, and new hope into a species that many feared might never see another calf born again.
In recent years, human threats to endangered right whales have increased, and given their fragile population status, the loss of even one of these marine mammals can have a massive impact on the fate of the species.
If we don't make sure that today's young people enter adulthood with their eyes wide open to the importance of protecting our living planet, then we are all -- elephants, animals, ecosystems, people -- in deep trouble.
