Gambling is not the problem but rather getting addicted so I think your choice of subject matter should've been "The solution to gambling addiction" cause when one gambles responsibly they'll avoid getting addicted and enjoy the fun of the game, giving solutions to gambling means you're trying to find a remedy to it, but I don't think it's something that can be stopped, it's become part of human nature cause the majority gambles even though some don't do it very often, gambling have been existing for ages that's why i doubt if it could be stopped globally, we should rather advice people concerning gambling addiction, how to avoid it and give possible solutions to those that couldn't avoid addiction, and not gambling itself cause it's come to stay.
