In a section that shocked 1971 readers, Odum redefined pollution. He suggested that adding heat (thermal pollution) or organic waste is a "subsidy" that throws the metabolic ratio off. While a small subsidy speeds up a system (e.g., fertilizing a field), an over-subsidy causes euthrophication and crash. He provided the mathematical framework for environmental impact assessments (EIAs), which became law in the US shortly after.
Despite being published over 50 years ago, "Fundamentals of Ecology" remains a relevant and influential work in the field of ecology. The book's principles and concepts continue to inform contemporary ecological research, including studies on ecosystem services, conservation biology, and environmental science.
: He treated energy as the common currency of all biological systems, using flow diagrams to explain how ecosystems maintain stability.
