Climate Change
              Have you ever sat in a car or bus parked under the sun with closed windows for a long
              time? It’s much hotter inside because the heated air is trapped. Similarly, the Earth is
              becoming hotter due to the burning of fossil fuels (coal, petrol, diesel, etc.). These gases
              trap heat, leading to global warming, known as the “greenhouse effect.”

              Harmful Radiation
              The atmosphere, particularly the ozone layer, protects us from harmful solar
              radiation.  This  layer  is  composed  of  ozone  gas.  However,  substances  like
              chlorofluorocarbons (CFCs), used in cleaning agents and refrigerants, deplete
              the ozone layer, creating holes that allow harmful radiation to reach Earth,
              increasing the risk of health issues like skin cancer.

                                        Natural Disasters
                                        Natural  disasters,  including  floods,  earthquakes,  landslides  and  storms,  are
                                        sometimes  worsened  by  human  activities  such  as  building  large  dams  and
                                        structures, which exploit natural resources and can aggravate the impact of these
                                        calamities.

                SAVING THE ENVIRONMENT

              To save our environment, we need to educate people. Education is important, as it gives people the knowledge
              and skills that they need to perform.
              1.  Learning about the environment: This involves acquiring knowledge and understanding our surroundings
                 and environmental issues.
              2.  Learning through the environment: This refers to engaging with the environment inside and outside the
                 classroom, focusing on hands-on experiences, problem-solving and direct environmental interaction to
                 acquire knowledge, skills and practical experience.
              3.  Learning for the Environment: This aims to develop informed and responsible behaviours towards the
                 environment, promoting efficient resource utilisation, green processes and technologies in businesses and
                 daily activities.
