This episode pairs greatly with the previous episode about Leaving things better than you found them, because when you buy from a company that means you are supporting their methods. Most company's methods involve single-use plastics and other decisions that are very harmful to our planet. These few companies were created with eco-friendly intentions and you buying from them supports their ideals.
Try any or all of these companies mentioned in the podcast episode, and no I don't get any commission! I only have the hopes of helping you all realize that we can be consumers with a purpose of improving the world.
