This episode talks about human changes on Earth, and how these changes can never be reversed, or at best can only be reduced if we move within a certain period of time, it's too late. For example, harmful radiation released into our environment by man's numerous nuclear tests of the last century contaminated the Earth's atmosphere and water, and natural radiation levels could no longer be reached before the nuclear weapon. The panel also touches on the crisis of climate change as one of the serious changes caused by the industrial revolution, and how the neglect of this dossier and the lack of attitude at present exposes humanity (and life on the planet in general) to damage that we will not be able to remedy in the future.
