An environmentally friendly choice for cutting boards would be to choose wooden ones, either bamboo or hard wood from a sustainable forestry source. Avoid getting a plastic board, both because it's a good idea to reduce plastics in your life and also because it is not as safe as wooden boards, which have natural antibacterial properties. Moreover, wooden boards don't get the deep cut marks that plastic boards can get, so they last longer and are less likely to harbor bacteria or introduce plastic into your food.
