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.
What happens when you flip a light switch or press the power button on the TV? Electricity flows to the device and it turns on. Most of us use electrical gadgets all day, every day, without thinking about it. This book follows the journey from source to resource of solar power, one of the most exciting forms of renewable energy today. Readers will learn how electricity is made and collected directly from the sun and how it reaches us to power our modern world. Other sources of energy are also examined, as well as how grids work to move electricity across land and sea, and how it is fed into our homes. Real-world examples look at solar farms, solar furnaces, solar towers, and even solar transportation. With the world's nonrenewable resources such as oil running out, the advantages and disadvantages of solar power as a renewable alternative are discussed.
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.
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.

Metal ores are one of the Earth's most common minerals. Metals are useful in all types of industry because they last a long time, are conductors of electricity, and can be easily shaped. Since the first metal alloy was created more than 6,000 years ago during the Bronze Age, people have recognized the potential of extracting metallic elements from rock. Metals traces the history, uses, methods of extraction, and future of one of our most versatile resources. Topics include: early use of metals during the Bronze Age, the Iron Age, and the Copper Age which countries have the most deposits of metal ores, and how much metal different countries use extracting metals from ores by use of smelting, flotation, and leaching the equipment that geologists use to locate metal deposits in ore the lives of miners, including their working conditions, the equipment they use, and the dangers that they encounter working in open-pit and underground mines the role that recycling plays in saving our environment and how metals are recycled
