Ugo Bardi is a polymath who started his career as a chemist working on oil refining, to gradually move to study peak oil and then the trajectory toward collapse that society is following nowadays. He was a faculty member of the University of Florence, Italy. Now he is a member of the executive committee of the Club of Rome, a think tank located in Switzerland, known for having supported "The Limits to Growth" study of 1972.

Ugo is known for several studies in the field of biophysical economics, and his best known proposal is that of the "Seneca Effect," a way to explain why collapses are frequent in our world; so named after the ancient Roman philosopher Lucius Annaeas Seneca

Ugo's books have been imaginative essays dealing with several facets of the human interaction with Earth. How we overexploit resources, how we generate heavy pollution, how we overpopulate the land. And what we can expect for the future in a vision that looks for harmony with the Goddess of Earth, Gaia.

Ugo's most recent books are is "Limits and Beyond" (Exapt Press, 2022), and "Exterminations" (Kimaira Edizioni, 2024). His next book, in preparation, may be titled "The End of Overpopulation"
