Ep 11. Coming of Age in the Anthropocene

In the episode "Coming of Age in the Anthropocene," the second season of Cosmos takes a closer look at the current geological era - the Anthropocene. This era is marked by the impact of human activities on the planet's ecosystems, atmosphere, and geology. Host Neil deGrasse Tyson explores the consequences of this impact and the responsibility we have as a species to mitigate our effect on the planet.

Throughout the episode, Tyson compares the current era with past geological eras, highlighting how human activities are causing a rise in temperature and subsequent sea levels. He explains how the Arctic sea ice is melting and the polar regions are witnessing the fastest change as the planet warms. The episode showcases stunning footage of glaciers melting, coral reefs dying, and forests being destroyed. Tyson argues that the warnings signs are clear and that humanity must alter its course to avoid further damage.

The episode acknowledges that there is still much we do not understand about the complex systems of the planet, and that we must continue to use science to investigate and understand our impact. It highlights the importance of research and innovation in creating a more sustainable future for the planet.

Tyson also discusses the concept of "planetary stewardship," which means taking care of the Earth and its natural systems as if we were its custodians. He believes that while individual actions are important, it is ultimately up to governments and institutions to take large-scale, effective action to combat climate change. He points to the Paris Climate Accord, which aims to limit global temperature rise to below 2 degrees Celsius, as a positive step towards planetary stewardship.

The episode also looks at the increasing threat of global pandemics, which Tyson argues is linked to the destruction of natural habitats and the loss of biodiversity. He explains how viruses that were previously confined to animals are now crossing over to humans due to human encroachment on natural habitats. He also discusses the importance of understanding the role of microbes in ecosystems and how they can help mitigate the impacts of climate change.

The episode concludes on an optimistic note, highlighting the work of scientists and researchers who are developing innovative solutions to the challenges posed by the Anthropocene era. Tyson urges viewers to join the efforts to create a sustainable future for the planet, and acknowledges that "coming of age in the Anthropocene" presents an opportunity for humanity to grow and evolve as a species.

Overall, "Coming of Age in the Anthropocene" is a powerful and thought-provoking episode that highlights the urgency and complexity of the challenges facing our planet. Despite the bleak realities of the current era, the episode encourages viewers to take action and work towards a sustainable future for the planet and all its inhabitants.
