The video discusses the severe drought affecting U.S. states and the adoption of cloud seeding as a method to increase water supply. Cloud seeding involves using silver iodide crystals to encourage snow formation. While proponents argue it is effective and cost-efficient, critics point out its limitations, such as the need for existing clouds and potential regional impacts. The process may not create new water but redistribute it, raising concerns about its overall efficacy.
