Acharya Prashant highlights that the current environmental crisis is more severe than a potential third world war, as humanity is rushing toward a sixth mass extinction. He points out that three of the previous five mass extinctions were caused by carbon dioxide, which is the same issue plaguing the planet today. He explains that human senses often fail to detect these subliminal changes until they become fatal, comparing the situation to a virus that remains hidden before erupting into a deadly disease. Using the example of Canada, he illustrates how a mere five-degree shift in average temperature can determine the existence or total absence of massive ice sheets, warning that current temperature rises threaten to make the planet uninhabitable for almost all species.
