Car, train, ship or aeroplane — which form of transport is most harmful to the atmosphere? What do farming techniques such as agrochemicals do? What is 'acid rain' and what are effects of it? This book takes a look at the impact that our modern world is having on our surrounding environment, from our use of fossil fuels and our increase in global food production and building work, to the rise in our transport production. Discover what steps scientists and engineers, and even ordinary people, are taking to develop sustainable solutions to these problems, from replastering festivals to buildings bound together using horse hair!
