into the VA3 cage. And that's what happens sometimes. You start introducing species into an ecosystem to get rid of, let's say, a non-indigenous species or troublesome species, thinking that it's going to solve a problem. In fact, it just exacerbates the problem by introducing another foreign species where it shouldn't be. And that just wreaks havoc with the local ecosystem. Lake freighters, or freighters coming in from other countries, pulling into ports in Canada here, U.S., etc. They're village tanks. Sometimes they're village tanks. They have species, native species, that therefore get released in the fresh water supply. Some of them survive, some of them don't. Zebra Muffles, that's a perfect example there too. Lake Ontario is just inundated with Zebra Muffles. and that was a non-native species that was introduced through tankers and ships coming in. Any additional comments for Tom before we head off? Oh, Tom, one more for you, too. The tornadoes, at one point in time, I'm not sure you may know exactly when they stopped doing this, but at one point in time it was believed, open your windows, allow the interior of your home to equalize, the pressure to equalize. And basically all that did is introduce high pressure winds your home and destroy it from the inside. And now it's better just to keep your windows closed. I don't exactly know when they stopped doing that, but that used to be a thing.
