Beef Hormone Dispute

Okay kiddo, so some people like to give cows hormones to help them grow bigger and faster. But other people don't like that because they think it could be bad for the cows and for people who eat the cows. So some countries don't let cows with hormones on them come into their country. This makes some people mad because they want to sell their cows to those countries but they can't. So now they're arguing about if it's okay to give cows hormones or not.
