This is how big fish die out from overfishing so all that is left is tiny fish we can't eat. This picture is an infographic by Don Foley and is from the book "Oceana: Our Endangered Oceans and What We Can Do To Save Them". This book is a really good book. I read it all the time and really like it. You can see more information about overfishing and this infographic at oceana.org.
