Interview with chemist and geneticist Flávio Lewgoy, who was also an expert criminal and environmental investigator. Lewgoy was at the center of important struggles for human health and environmental quality in Rio Grande do Sul, and was one of the people behind state (1982) and federal (1989) laws governing pesticide use. He believed he had a duty to use scientific knowledge to support his positions on environmental activism and saw this activity as an ethical commitment, a way of paying back society for the education he received in public institutions.
