Global warming


           The emission of gases such as carbon dioxide creates a layer of trapped heat
           in the atmosphere. This causes Earth’s temperature to rise. The continued
           increase in the temperature causes ice in the North and South Poles to melt
           and thus, raising the sea level. As the coasts are submerged, the coastal
           animals and plants lose their habitats.






          Less heat is released
          back into the space
          which causes Earth to
          become warmer.

                    Gases from factories and vehicle exhaust fumes increase the
                    volume of carbon dioxide in the air. These gases create a layer that
                    traps heat.
