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.
Actions for Saving the Environment
Aspect Avoid Prefer
Air Pollution Burning materials (e.g., wheat or rice Using natural ventilation or fans instead of
straw) air conditioners
Energy Use Leaving lights or appliances on Using public transport, cycling and opting
when not needed for solar or wind energy
Water Pollution Throwing waste in rivers and lakes Using recycled water or rainwater for
watering garden plants
Waste Management Using plastic bags Segregating waste before disposal to
ensure biodegradable waste is composted
Chemicals in Food Using chemical pesticides or Consuming organic, chemical-free food to
fertilisers promote organic farming
Forest Plants Overusing paper Reusing paper for making paper-based
products
Water Overusing water Reducing water use during bathing by
using a bucket instead of a shower
