When we are born, we are basically sterile. By the time we die, we are more microbe than human. Microscopic organisms are essential to the development of human life. Until Antonie van Leeuwenhoek observed his own microbes under a self-made microscope in the seventeenth century, we were not even aware that they existed. Clinician-scientist Fergus Shanahan and graphic design artist Laura Gowers shed light on the microbial world. How can we nurture microbes in the face of the climate emergency? Why do Irish Travellers have a unique microbiome? A remarkable, ground-breaking graphic book.
