The new approach to ecosystem health is proactive. As a result, the scope of environmental studies is growing and the methods are evolving. Integrated Assessment of Ecosystem Health aggressively broadens the range of ecotoxicology to include its related fields.The book begins with John Cairns, Jr.'s predictions and recommendations for the future ecotoxicology: "New goals must lead to new techniques.... the field of ecotoxicology is in the early stages of a major paradigm shift that is driven by three interrelated forces: 1) heightened interest in sustainable use of the planet, 2) protection of ecosystem , and 3) the shift from emphasis on avoiding deleterious effects to maintaining them in robust health." Later chapters explore the integration of data, intrinsic remediation studies and the ever- increasing number of associated disciplines that are improving our environmental potential. Methodology, itself, is considered as an evolving tool, always in need examination and revision. Cairns, and his co-authors all advocate a constructive, offensive new form of ecoscience. The consensus of scientists is clear: toxic threat and, especially, habitat destruction are the most important environmentl issues, today. The mandate from Integrated Assessment of Ecosystem Health is also decisive: expand the parameters of ecoscience. The future of life on earth depends upon our ability to grow and learn.
