Most of us eat three full meals a day, but where does the food that reaches our plates, stocks our fridges, and fills the supermarket shelves come from? This informative book shows how methods of growing, using, and delivering food - one of the most vital resources to humans - have developed and changed throughout time. Find out about the history of food production and present-day methods of farming. Learn about food delivery, the processes used to preserve and store food to make it last longer, how different foods are prepared, and food safety. Real-world examples encourage discussion of the ethics and worldwide impact of the production, distribution, and consumption of this global resource.
This timely book looks at the world's production of oil and our dependence on this natural resource. The majority of today's forms of transportation run on fuel that comes from oil, and hundreds of thousands of the items we use every day come from oil or oil-based products. Readers will find out about the origins of oil and its first use in industry, and learn how it is found, mined, and processed into many different products that are used all over the world. Real-world examples also consider the environmental and human disasters related to oil, encouraging discussion of the ethics and worldwide impact of the production, distribution, and consumption of this global resource. Possible alternatives to using oil are also discussed now that this important, non-renewable natural resource is running out.
Most of us use water all day, every day, without thinking about it. But how does it get to our homes? From the pitter patter of raindrops to the whoosh of water from the shower, this book follows the journey from the source to the resource. Water is one of the most vital natural resources for humans, and we use it in abundance for more than just drinking water. It is used in household chores, leisure activities, and in work and industry. Readers will learn about where water comes from and the water cycle, as well as how water is stored, treated, and pumped around the country and into our homes. Real-world examples consider the environmental impact of our water use and how we can reduce consumption in our daily lives, and how many people live in places around the world that do not have a reliable water supply and rely on local methods to clean water that is in short supply.
Imagine your family had to choose between sending you to school or having enough food to eat. This book tells how William Kamkwamba was forced to drop out of his school in Wimbe, Malawi, when a famine struck his village and his family, who relied on farming, could no longer afford his tuition fee. Instead of giving up on his education, William visited his local library often. It was here that he read a book about wind power. At the age of 14, William used what he learned from the book to build a windmill that brought power to his family’s home. He has since built his village’s first drinking water pump. William’s ingenuity, perseverance, and initiative are an inspiration to many people around the world.
