Disposable straws are usually made from plastic and plastic never breaks down. As time goes by, plastic will separate into smaller and smaller pieces, but never completely biodegrades. Plastic is quickly transforming our oceans into plastic soup… In the USA alone, 500 million straws are used every single day. We use straws for around twenty minutes before we toss them away, which is an astonishingly quick lifespan for an item that will be on the planet forever. Straws also contain BPA, and can’t be recycled.
You can buy reusable straws made of metal, bamboo, silicon, and other materials–and even little drinking straw cleaning brushes to keep them clean on the inside. An online search will bring up many alternatives available for sale.
