Utopia is a small country that relies on tourism for the majority of its foreign earnings. A recent environmental study found that plastic waste was a serious threat to the environment of Utopia. The usage of plastic containers and bags by foreign tourists accounts for 50% of the plastic waste in Utopia. The Prime minister of Utopia is considering two policy options to tackle this problem.

Policy A - Every foreign tourist will be required to pay a $100 fee for entering Utopia.

Policy B - Imposing a significant tax on the sale of plastic containers and bags.

Which policy would you recommend to the Prime minister of Utopia and Why?
