# List of The Nature of Things episodes

The Nature of Things (also, The Nature of Things with David Suzuki) is a Canadian television series of documentary programs. It debuted on CBC Television on November 6, 1960. Many of the programs document nature and the effect that humans have on it. The program "was one of the first mainstream programs to present scientific evidence on a number of environmental issues, including nuclear power and genetic engineering". The series is named after an epic poem by Roman philosopher Lucretius: "De rerum natura" – On the Nature of Things.
