You've probably seen that painful video of vets pulling a straw out of a sea turtle's nostril. I had to look away. So much of what we use comes in plastic and much of it ends up in the landfill or the ocean.
Dianna Cohen is passionate about getting plastic out of her life. The short video has some good ideas, beyond the canvas grocery bag.
FYI: A friend of mine has recently launched a shampoo/conditioner line that is in bar form (so no plastic bottle) called HiBAR. I really like it. It doesn't get goopy like a wet bar of soap as long as it's sitting on a dry shelf in your shower. And it's great for traveling because it doesn't count toward your liquids baggie.
