The pigs additionally scavenge by means of trash which exposes rubbish and in flip attracts birds, thus creating points for close by airports and seaports.
“It’s hard to imagine you can damage trash, but you can … if we don’t cover it deep enough, the pigs will dig it and eat that trash and it opens up to birds coming in,” Bodenchuk advised the Edmonton Journal.
