Plastics cause pollution and damage to the environment during its entire lifespan. After all, plastic is made from oil (a non-renewable fossil fuel), and plastic pollution can harm or even kill a large variety of marine animals. 
One way to reduce the impact of plastic on the environment is to simply stop using single-use plastics. 
Reusable stainless steel products are such an amazing alternative. They are much better than plastics, for more than just the reason of benefiting the environment!
