I read a fascinating article about inventive ways the border patrol can protect us. It was in the Wall Street Journal. One invention is a "squid" with tentacles that can reach out and stop a car. But the one that worries me is to import a wasp from Spain that likes to live in the type of plants that illegal immigrants hide in.
Remember killer bees? They were imported and are now spreading and hurt regular non-aggressive European honeybees. The Japanese beetle was supposed to be beneficial, but it isn't. Ticks came in on sheep from overseas.
I think we need to be really careful about bringing in these wasps. They could upset still another ecosystem. Does the EPA know what Homeland Security is doing? What will the unintended consequences be?
