How did the universe and life begin and what are the threats to people and the environment in a pandemic?This book is for anybody with interest in protecting life on the planet.Studies on the origin of life and scientific contributions to safeguarding the planet are examined in light of current thinking on climate change.A major focus is the spread of microbes, put in the context of environmental assessment and management, including descriptions of microbiomes and a consideration of the risks of genetic modifications.Professor Lynch shows how failure to control disease can lead to the collapse of any biotic population.To avoid this, the ethics of management of disease by biological control and by vaccination are discussed, at the practical level and in a moral theological context.
