This is a no brainer. All you need to do is decline the straw! If you really need to use a straw then the best thing to do is to buy a reusable one. You can literally get these anywhere! So why are people still using the plastic ones? Is it for chewing? There are different straws that you can use and here they are.
Brands like Glass Sipper and Enviro Glass Straw are eager to eliminate the use of disposable plastic straws and draw more people into a more sustainable way of life. Personally I like the bamboo straw as it doesn’t feel weird on my teeth and if you need a new one then you can just throw it in the compost.
