Carbon dioxide (CO₂) is a natural part of Earth’s atmosphere and plays an important role in regulating the planet’s temperature. However, human activities like burning coal, oil, and gas have caused CO₂ levels to rise sharply. This excess CO₂ traps more heat, intensifying the greenhouse effect and leading to global warming.

The effects are becoming clear: glaciers are melting, sea levels are rising, and extreme weather is more frequent. Reducing CO₂ emissions is essential to slow down climate change. This can be done by switching to renewable energy, using public transport, and protecting forests.

Even small everyday actions can help – like saving energy, eating less meat, or choosing local products. Everyone has a role to play in protecting the planet.
