Are plastic bans effective?

I've been reading a lot about the debate surrounding plastic bans, and I'm curious to know if they're truly effective in reducing plastic waste. On one hand, some argue that plastic bans can significantly decrease the amount of single-use plastics that end up in landfills and oceans, protecting wildlife and improving public health. However, others contend that bans are ineffective, as they often lead to increased use of alternative materials that may have their own environmental impacts. Additionally, enforcement can be challenging, with some businesses and individuals finding ways to circumvent the rules. So, what's your take on the matter? Are plastic bans an effective solution to the plastic waste problem, or are there better alternatives?
