Five Facts - Ozone Layer

The video discusses five key facts about the ozone layer. It explains that ozone is a blue gas with a chlorine-like smell, and highlights its crucial role in protecting Earth from harmful UV rays. The ozone layer helps regulate Earth's temperature by absorbing and trapping heat. Greenhouse gases, resulting from human activities, can damage the ozone layer, but global efforts have led to its recovery, with predictions of full restoration by 2065. The video emphasizes the importance of continued environmental action.
