Airplanes and Other Man-Made Cloud Machines

The video explains how contrails, or condensation trails, form when planes fly at high altitudes, emitting particles that act as cloud seeds. These man-made clouds can vary in duration based on atmospheric conditions. The video also discusses other man-made clouds, such as ship tracks and those from power stations, and their environmental impacts. Solutions like using biofuels and renewable energy are suggested to reduce these effects.
