In recent years, a number of eco-friendly toothbrushes have been developed: some made of wood, bamboo, and other materials.
This is an amazing and simple green technology example that allows reducing plastic waste.
Switching to a sustainable toothbrush is a simple step that everybody can do, especially now that alternatives of great quality and design are becoming available!
Plastic pollution is one of the greatest environmental problems of the modern era and over 1 billion plastic toothbrushes are thrown away every year just in the United States.
About 99% of toothbrushes are made of plastic, a material that takes more than 400 years to decompose and is polluting our land and oceans!
