Animal Populations That Are Out of Control


The Damaging Effects of Wildlife Overpopulation

Wildlife overpopulation is a serious concern throughout much of the world. Some regions get the bright idea to introduce new species of animals into the local ecosystem, only to see the new species flourish until nothing else can survive. Wildlife overpopulation occurs when one species multiplies so fast that its predators can’t keep up. The birth rate goes through the roof, while the mortality rate dips to historic lows. These animals tend to wreak havoc on the ecosystem’s existing wildlife, doing lasting damage to all sorts of other species. Find out which animal species are causing all the trouble.

Beavers Take Argentina

Back in the 1940s, Argentineans brought a few dozen beavers back from Canada to help boost their nation’s fur trade. They hoped that the beavers would acclimate well to the local ecosystem, but the animals ended up overstaying their welcome. Today, the local beaver population in Argentina is out of control, with beavers damming rivers and streams and tearing down dozens of vital forests. To make matters worse, trapping and killing all of these excess beavers has become quite the challenge.

Lionfish in Paradise

The tropical ecosystem of the Bahamas was pretty stable until the early 1990s. Lionfish have been dominating the crystal-blue waters ever since. Scientists believe that the problem started when a massive hurricane damaged the country’s aquarium, leaking new species of fish into the sea. Lionfish have now emerged as one of the greatest threats facing this gorgeous strand of islands. They’re eating just about anything in sight, endangering other local species. The grouper is one of the lionfish’s most aggressive predators. Environmentalists have been doing everything they can to boost the grouper population as a way of keeping the lionfish in check.

Jellyfish Vs. the World

In addition to stinging the occasional tourist, jellyfish are quickly dominating the global seas. What are known as jellyfish blooms are continuing to pop up all over the world. As the jellyfish population continues to explode, fishermen are pulling up giant globs of slime off the ocean floor. The fish that compete with jellyfish for food are getting caught left and right, giving these gooey creatures the freedom to eat up everything in sight. Scientists are worried that if this trend continues, jellyfish will start disrupting entire ecosystems, driving down the world’s aquatic biodiversity.

It’s White Tailed Deer Season

Get your guns, because it’s deer season in the U.S. The white tailed deer population in the U.S. is at a record high. Despite being the number one target for most hunters, these nimble creatures are running rampant. They’re venturing off into new territories, swallowing plant life wherever they go. Of course, environmentalists have their concerns about declaring war on the country’s white tailed deer population, but something needs to be done before we see some plant species disappear for good.
