2. Hello, I am air. I am mainly composed of Nitrogen (N2), Oxygen (O2) and Carbon Dioxide (CO2). Help me to drag the components of air into the correct place below.

3. Do you know what is air pollutant? Lets click in the air pollutants to discover more!

4. Carbon monoxide (CO), also called carbonous oxide, is a colorless, odorless, and tasteless gas that is slightly lighter than air.

10. What you can do Reducing greenhouse gas emissions is the key to solving global climate change. A major way these gases get into the atmosphere is when people burn coal, oil, and natural gas for energy. Everyone uses energy, and everyone can be part of the solution!

Biomass Energy Biomass is a fancy name for material from plants and animals. Some kinds of biomass can be burned to produce energy. One common example is wood. Biomass contains stored energy. That's because plants absorb energy from the sun through the process of photosynthesis. When biomass is burned, this stored energy is released as heat. Burning biomass releases carbon dioxide. However, plants also take carbon dioxide out of the atmosphere and use it to grow their leaves, flowers, branches, and stems. That same carbon dioxide is returned to the air when the plants are burned.
