These are the only two books I'm reading right now but I have a long book list that contains similar titles. Being informed is so important if you want to make any kind of difference. The first step towards being more sustainable isn't using reusable bags, isn't changing your light bulbs, isn't feeling guilty about all the things that you aren't doing or can't do. The first step is knowing what is happening, what other people are doing to help fix the health of the planet, and then decide what changes and additions you can make to your lifestyle in order to do some good. Every little bit helps :) What are you reading?
