Soviet planners diverted two rivers to grow cotton in Central Asia, and the Aral Sea shrank by more than ninety percent. Segment 1 — The Cold Open In the late 1950s, Soviet engineers began digging massive new canals that pulled water from the Amu Darya and Syr Darya before those rivers could reach the Aral Sea. The goal was straightforward: turn dry steppe into reliable cotton fields that would st...

Japan's rice price supports kept steep terraces farmed until aging left them abandoned to bamboo and erosion. Segment 1 — The Cold Open In the steep hills above a village in central Japan, water still flows through channels that once irrigated neat rows of rice on narrow terraces. For decades those terraces stayed in production because government price supports made the crop profitable even on plo...

Post-Soviet Russia leased its Siberian forests for sustainable harvesting, but self-reported data turned the leases into cover for large-scale illegal logging. Segment 1 — The Cold Open In the vast taiga of eastern Siberia, companies holding long-term forest leases filed paperwork showing modest annual harvests and dutiful replanting. Satellite imagery told a different story: entire hillsides stri...

South Korea charged shoppers for thin plastic bags in 1999 to cut waste, only to watch manufacturers switch to thicker “reusable” film that escaped the fee and raised handling costs.
