The Greenhouse Gas Effect | The science behind trapping heat

The video discusses the enhanced greenhouse effect and its impact on climate change. It highlights the main greenhouse gases: carbon dioxide, methane, and nitrous oxide, explaining their sources and effects. Carbon dioxide is absorbed by plants and oceans, while methane is largely emitted by livestock. Nitrous oxide comes from fertilizers and industrial activities. The video emphasizes that not all greenhouse gases are equally potent, with methane being more powerful than carbon dioxide. It concludes with solutions to reduce emissions, such as planting trees, composting, and using energy-efficient technologies.
