Asian carp
A jumping Asian carp on the Missouri River. These non-native species can grow up to 110 pounds and outcompete native fish species for food. They have been spreading up the Mississippi River system since escaping from fish farms in the South, and have been seen in Minnesota.

A sign in Park County, Wyoming. Some ecologists say a militaristic approach to invasive species management can create more harm than good for local environments. Others say drastic measures, such as applying herbicides to large swaths of land, are necessary to control invasives.
