• A greenhouse is a building with glass walls and a glass roof that let in sunlight and trap in heat. Plants can be grown in greenhouses all year long because they stay warm throughout the year

• Greenhouse gases trap heat in our atmosphere, just like the glass walls and roofs of greenhouses. An increase of greenhouse gases in the atmosphere has caused our Earth to warm up very quickly

• Humans have been adding more and more carbon dioxide to the atmosphere. Most scientists believe that this increase of carbon dioxide caused by human activities is the main cause of global warming
