How Harmful Are Fossil Fuels?

Is burning coal still harmful today? What is fracking? What do we do when fossil fuels run out? This book looks at the potentially harmful implications on the state of our planet from the use of fossil fuels, discussing in depth the various techniques of fossil fuel extraction such as longwall mining for coal, the major effects of oil leaks and spills on the ocean and the reason for the heated debate about fracking. The book also looks at alternative energy sources such as biofuels, hydroelectric power and even a new type of rocket fuel.
