Yeah, no, that's probably the the nub of what we're what I'm trying to say is, although everybody well is, once you're aware of roads, you think it's a, it's a just a terrible, yet another wicked problem to face, you know, we have to have the roads and what can we do about it. And again, we face just despair. So this book is to really argue against that, that hopelessness, and to and to give lots of examples of just how spectacular and successful it has, we have been in terms of getting animals across roads. So you start with a simple road, every road in the world has got tunnels or culverts, or pipes underneath for the water--you can't have the water build up on one side of the road, it's got to travel through, so they're everywhere. Animals have always used those pipes, you know, when they're dry, they can, they can just walk through the through there and get across safe and little animals. Of course, mostly, they're small. So that's a bit building on that concept. There has been all sorts of other structures, much more designed not for water this time, but for animals to get through. So different sizes and shapes, and what we call furniture, the way they're designed inside, there might be places for animals to hide from predators, or all sorts of things. So that's now extremely well advanced is that those things are everywhere. But you don't notice because you just drive along the road above, and you don't see them. Probably without doubt, the most conspicuous of the structures to allow animals to get across the road are these huge wildlife overpasses and they're, you know, they are incredibly successful -- animals use them all the time, and immediately use them as soon as they're available. But of course, they're really expensive, you know, so you can't put them anywhere. And so they need careful thought about where to place them. And you've got to have good healthy populations on either side of the road. There's no point in living and going over to the one side where there is no prospect of having a life on that side. But it's all about enabling as simply as possible, the animals to move through the landscape without even noticing the road and being worried about it. So you saw I'm just skimming over the surface here. But we've now got underpasses for for animals to move under the road, and big overpasses. But there's other things as well, there are things we call canopy bridges, which are like a like a rope ladder, which connects the canopy on one side across the road to the other side. So animals that are our boreal tree dwelling, they don't even need to come to the ground anymore, they can safely cross this busy, dangerous place just by walking on this ladder. And in Australia and a couple of other places, we have gliding animals, so they don't fly, but they have wing kind of apparatus between their legs, and they can shoot off and float through the air for a long distance would they call gliders, Australia has lots of gliders. So we have the capacity to put up pole, a series of poles maybe 10 meters apart, across, you know, a busy landscape across, you know, a six lane highway, and the gliders will then you know, zip from one to the other and get across the road safely. And to my, you know, to everybody's surprise, they work really like a dream. You know, it takes a while for the gliders to work out what they are. But once they once they know, ah, we can use these for gliding - they weren't here yesterday, but they're here now. So let's go. So that just some of the some of the examples of some of the things some of the structures.
