Acharya Prashant highlights the catastrophic consequences of climate change, emphasizing that it will lead to massive displacement of people as land is lost to rising sea levels. This displacement will trigger international conflicts and potentially the next world war, as nations fight over remaining resources and land. He explains that during such wars, economic growth becomes irrelevant, and the GDP of nations collapses as all resources are diverted toward war efforts, leaving only the weapons and ammunition industries profitable. The prosperity for which humanity has sacrificed the planet will ultimately be taken away by the very environmental destruction it caused.
