Book excerpt: The relationship between sport and the natural environment is bidirectional; that is, sport impacts the natural environment and is impacted by the natural environment. Since the 1990s, sport management scholars have predominantly explored the ways the sport industry impacts the natural environment. They have done so through the lenses of sport sustainability, corporate social responsibility, and sport industry's influence on proenvironmental behaviors. Recently, a new line of research has emerged, exploring the impacts of climate change on the sport industry and adaptation behaviors of athletes, organizations, and fans. In this paper, the authors advanced the name sport ecology to formalize the subdiscipline of study on sport, the natural environment, and the relationship between the two.
