The first change needs to be teams pay for their own stadiums instead of them being taxpayer funded from cites and states. I don’t care if it will drive tourism, use that money to take care of the purple in the city and make the city a nice place, even make it a nice place for a stadium, but make the team owners/pro leagues pay for their own damn stadium.
There is a vaccine for chickens and turkeys for the bird flu. But poultry barns only use it when there are already outbreaks in their area, they don’t consider the cost worth it most of the time. And no one is giving it to wild birds.
