TED-Ed: M Jackson: How to grow your own glacier

The video explores the legend of Genghis Khan's ice wall and the historical practice of growing glaciers in the Karakoram and Himalayan ranges. It explains the differences between natural and artificial glaciers, highlighting traditional methods used by local cultures to create glaciers for water supply. The video focuses on Ladakh's innovative glacier solutions to combat water scarcity and describes techniques for creating horizontal and vertical glaciers. It concludes with the global spread of glacier growing practices, including modern innovations in the Swiss Alps and plans for expansion in other regions.
