I visited the library and found the book 'The Food Revolution: How Your Diet Can Help Save Your Life And Our World' by John Robbins. This resource was very helpful in writing about how meat production exacerbates the global water shortage. According to this book it is estimated that it takes 300 gallons to feed a vegan for a day, 4 times that to feed a vegetarian and 14 times to feed a meat-eater. I used this information when writing the paragraph about how meat production drains global water supplies. Another book I found was 'Diet for a small planet' written by Frances Moore Lappé. This book mentioned the problems of deforestation and desertification that arise from grazing animals for meat production. By finding two books I had broadened by bibliography so that I had a wider range of resources which was successful. I will continue to find more resources that can be used when writing my dissertation.
