Exploring the Greenhouse Effect and Global Warming

The video discusses Earth's unique atmosphere, which maintains stable temperatures, and the greenhouse effect, essential for life. However, human activities have increased greenhouse gases, leading to global warming. The video highlights the consequences of global warming and international efforts like the Kyoto Protocol to reduce emissions. It also suggests individual actions to combat climate change, such as planting trees, reducing waste, and using renewable energy.
