What’s Scarier Than Lions, Tigers and Bears? Life Without Them.

Remember that tourist video of a lion pride and a crocodile playing a deadly game of tug-of-war with a buffalo calf? Just when the lions seemed about to triumph the buffalo herd came charging to the rescue. If you’re like most people you cheered when the baby buffalo got up and staggered back to its herd. For some reason, we humans rarely root for the predator. But if we know what’s good for us, we better start.


A recent study in the journal Science, "Status and Ecological Effects of the World's Largest Carnivores," finds that life without top predators is a scary prospect for the planet—and us. 31 carnivore species weighing over 15 kilograms were analyzed. After reviewing over 100 different surveys the authors conclude that losing predators from ecosystems causes those ecosystems to unravel. The effects range from an increase in pest animals, wildfires and diseases, loss of beneficial species, rivers changing courses, desertification and speeding up of climate change, to name just a few.

Even with all our technology we humans cannot duplicate the ecological services these predators provide for FREE 24/7/365 days a year.

Tragically, more than half of these 31 carnivore species are at risk of extinction. A growing human population, loss of habitat, loss of prey, climate change, trophy hunting and poaching are taking a toll on these keystone predators. And all those threats can be traced back to one source: humans.

But if we’re the ones causing the problem we can also be the ones to solve it. We're an innovative species capable of some pretty incredible feats. Recognizing the problem is the first step. Encouraging our political leaders to do something about it is the next.

Please stick up for our fearsome friends. It’s for our own good.
