The number of plastic bags found on UK beaches has dropped a huge amount since the government started making people pay for them.
A group called the Marine Conservation Society has been tracking this for years, and they've seen a whopping 80% decrease in plastic bags.
This shows that charging for single-use plastic bags really does work to reduce the amount of litter on our beaches.
It's a great example of how we can make a positive impact on the environment by making small changes to our habits.
