Acharya Prashant explains that the current approach to climate activism, such as tree plantation, is often ineffective because it fails to address the root cause of the problem. He points out that while planting a tree might absorb one ton of carbon dioxide over forty years, having one less child can save sixty tons of carbon emissions per year. He argues that misplaced activism often serves as a way for individuals to feel they have done their bit, which then absolves them of responsibility and allows them to continue harmful behaviors. He emphasizes that the opportunity cost of such activities is high, as the same time and energy could be spent on more impactful awareness campaigns regarding population control.
