Enter the world of the microbe and find out about their vast numbers, appearance and purpose. Though microscopic in size, microbes are essential to our daily lives and help shape our world. They can turn rock to soil, food into compost and milk into yoghurt, and while the 'bad' ones (germs) may make us ill, the 'good' ones help to keep us healthy. A much-needed science book for the early years.
