 makes them heavier and it makes them hungry. So it fills up their bellies and they can't get rid of it. But then they can't hold nutrition. They feed it to their chicks and then the chicks can't develop because they're full of plastic and they can't fly. And it also, I mean, one of the other things with the plastic is it's not just about all the stuff I'm talking about, crabs getting stuck in it, birds choking on it, whales choking on it, all of that stuff that we know. What happens is the plastic breaks up once it's in the water. So it breaks down into what they call microplastics.
