From the physical and social well-being of an individual to the functioning of an ecosystem, health has many different meanings and applications. More than just the absence of disease, health implies a state of well-being. Ever since the origin of life, physical, chemical and biological factors have impacted the health or biological status of living things. And in response life has evolved immune systems, detoxification systems and redundancies to stave off infection, disease, and toxicity. As the world becomes more interconnected, and industrialized, diseases never seen in one part of the globe now threaten to devastate human, wildlife and plant populations, while industrial chemicals now contaminate life in the most remote regions. Maintaining health, whether ecosystem, human or microbial arguably presents one of the greatest challenges of the day.
