Most of the food we eat today comes from farms, but the processes farmers use to produce it have changed greatly over the years. This fascinating volume explores the many different types of farming that exist in the world today—from organic farming to the use of genetic engineering on crops. Readers discover how farming affects the environment and get a detailed look at various kinds of farms and the future of farming with the help of vivid photographs. A topic web shows how the information learned in this book can be carried over into worlds as different as history and art.
