Acharya Prashant explains that mass extinction refers to the accelerated rate at which species are disappearing. He states that while there is a natural rate of extinction, this rate has increased by almost a thousand times in the last hundred years due to man-made, or anthropogenic, reasons. He clarifies that this is not about the loss of individual members but the disappearance of entire species forever. This crisis is linked to other environmental issues, such as the 1.5-degree Celsius rise in the planet's average temperature and the increase in atmospheric carbon dioxide concentration from a natural 280 ppm to around 450 ppm. He calls this the sixth extinction phase, noting that three of the previous five were also caused by an abundance of carbon dioxide, the same situation we see today. The speaker emphasizes the urgency of this issue, stating it should be the top priority for all institutions, but it is not being discussed. He directly links the problem to the growth of the human population from six to eight billion, asserting that every new human born is a "death warrant" for at least ten thousand members of other species. This is because humans do not merely exist; they exist to consume. Unlike other animals whose consumption footprint has remained stable, the human consumption footprint has grown exponentially. He argues that at current consumption levels, not even a dozen Earths would suffice, a fact he describes as pure arithmetic. This consumerist drive is fueled by a flawed philosophy that equates happiness with consumption, a mindset that our education system has unfortunately fed us. When asked about the role of religion, Acharya Prashant distinguishes between religion as it is commonly practiced and its spiritual core. For most, he says, religion is merely culture, tradition, and hearsay, with few people actually reading their scriptures like the Vedas or the Bible. He argues that this superficial form of religion is often manipulated by a priestly class with vested interests. True religion, or spirituality, can provide an answer if one penetrates its outer shells to its core. He explains that science and spirituality are two different domains: science studies the objective universe, while spirituality, or Advaita (non-duality), is about understanding the inner subject, the 'I'. Advaita means realizing that the cure for our restlessness does not lie in the external world. The world should be a means to help one penetrate into oneself, not an end to be exploited for desire. When one is clear inside, one knows what to do with science, using its power for self-fulfillment rather than self-destruction.
