Globalization and climate change are bringing invasive species to the U.S., disrupting ecosystems and wreaking economic havoc. There are more than 50,000 alien species in this country, and they’ve often been able to outcompete—or eat—native flora and fauna. Time magazine senior writer Bryan Walsh explains why the problem seems to be getting worse. His article “Invasive Species: From Giant Snails to Asian Carp, Alien Wildlife is on the Move” in the July 28 issue of Time.

We need to work on making cellulosic ethanol. Then we can make it from kudzu & solve 2 problems at once!

I saw a prominent shopping channel selling an aggressive vining grape plant from Japan. They actually touted that it was a fast/aggressive grower. Why isn't this regulated?

Are wild horses considered an invasive species in North America? They did not exist here until brought in by the Spanish conquistadors.

RE: Asian Carp? Why don't fishermen take and sell them for FOOD?
That would deplete the supply.

How invasive are earthworms? I've heard this called Global Swarming.

Once we label some plant or animal invasive (always a human fault for introducing the creature) we set up a task force and then kill it.
