Understanding the Greenhouse Effect

The video explains the greenhouse effect, a natural phenomenon essential for life on Earth. It compares the Earth's atmosphere to a greenhouse, highlighting how gases like CO2 trap heat. The video discusses the increase in CO2 due to industrial activities and fossil fuel use, leading to global warming. It outlines the consequences, such as water shortages and rising sea levels, and suggests solutions like recycling and renewable energy.
