Understanding Shifting Baselines

The video discusses the concept of shifting baselines, illustrating it with three stories: Charles Darwin's observations in Galapagos, changes in tilapia size in West Africa, and the impact of trawling in Southeast Asia. It explains how generational perceptions adjust to new environmental baselines, often overlooking past abundance. The importance of marine protected areas in resetting these baselines is highlighted, along with the potential role of art and film in evoking lost natural states.
