When Uganda suddenly became a major transshipment point for wildlife smugglers, Amooti alerted Ugandans to the problem. In September 1994, he helped two American undercover wildlife agents mount a sting operation at Entebbe airport. Putting himself at great personal risk, Amooti exposed the smuggling of endangered chimpanzees and African Great Grey parrots–both endangered species protected by the Convention on Trade in Endangered Species (CITES)–by airport personnel, game officers and businessmen. Ugandans became very concerned about wildlife trafficking and as a result authorities have been catching a higher proportion of smugglers.
In 1997, Amooti fought off a plan to spray Lake Victoria without an environmental impact assessment. He also averted government action to degazette a unique forest for use by industry and completed a series of environmental books for young people. He passed away in 1999.
