Honestly, I haven't yet read this book, but I took the quote from Goodreads at: https://www.goodreads.com/work/quotes/880193-silent-spring. I figured a quote from this book was fitting this month, as it is Earth Month in the US (and Canada) and it was Rachel Carson who first brought us the need to pay more attention to our environment with this book. I hadn't known for years that she and this book were responsible for so much of the environmental movement until I read Headstrong: 52 Women Who Changed Science-and the World last year. 

Personally, I've been loving all the stuff about women in science and have a few of t-shirts of them. I got them from Redbubble. There's an artist, Hydrogene, that makes the best t-shirts and posters of the women in science, I just can't rave about it enough. There's a great design for Rachel Carson, check it out here.
