Invasive species: From the classroom to the creek

A survey of 2000 science teachers in the United States and Canada found that, of those who used live animals in the classroom, 1 in 4 were releasing those animals into the wild afterwards. Why worry about that? Because the animals they reported releasing were often potentially invasive species: including crawdads, amphibians, and aquatic plants. The survey results don't show a massive trend here, but it's something to think about, given that teachers are not usually considered when state agencies create programs to prevent invasive species release.
