I really love this series and I love the optimism that Hannah Testa brings to the plastics crisis. I loved the expansion of the 3 Rs to 5. One thing I think this book was lacking was the cost of being eco friendly. She acknowledges that companies and brands need to do more, but still, most of the tips put the responsibility on individuals. Swapping what you use for more eco friendly variations can be costly and with so many Americans living paycheck to paycheck, it's not as easy as she made it seem. There was also a lot of talk about how plastics from one place can end up on the other side of the world, but I wish the book had really emphasized how the west and industrialized countries are responsible for the climate crisis while other countries deal with the majority of the cost. Overall a great, short, concise read.
