About this item

Something as small as a seed can have a worldwide impact. Did you know there are top-secret seed vaults hidden throughout the world? And once a seed disappears, that's it - it's gone forever? With the growth of genetically modified foods, the use of many seeds is dwindling - of 80,000 edible plants, only about 150 are being cultivated. With a global cast of men and women, scientists and laypeople, and photographic documentation, Nancy Castaldo chronicles where our food comes from, and more importantly, where it is going as she digs deeper into the importance of seeds in our world. This empowering book also calls young adult readers to action with suggestions as to how they can preserve the variety of one of our most valuable food sources through simple everyday actions.
