Human activity has undoubtedly impacted our planet’s systems. With deforestation, air pollution, and plastic waste, can we still call the natural sciences “natural”? Or have humans changed the planet so much that the “natural” and “human” worlds are now indistinguishable? Could seeing ourselves as part of the earth’s systems help bring more urgency to the climate crisis?

In the final episode of this four-part series, Bob Brinkmann, author of Practical Sustainability: A Guide to a More Sustainable Life, discusses the dynamic field of earth sciences. As humans continue to impact the “natural” world, the earth science disciplines must come together to study major issues like climate change and sustainability—not get bogged down by the silos or traditions of higher education. In addition, Bob digs into how librarians can assist in sustainability research through the available data in special collections and frequent communication with scholars. Last, he emphasizes the importance of measurable outcomes in the sustainability movement, along with becoming an advocate and evangelist for this kind of lifelong work.
