SUPW Assignment: Environmental Issues in School
Introduction
Schools are second homes for students. The environment in which we study plays a major role in our
health, comfort, and learning ability. While some problems are openly discussed, others are often ignored.
Two such issues are food waste in canteens and the effect of LED lighting on eye health. Both are
relatable, yet not always spoken about. By understanding these issues, we can find solutions to make our
schools healthier and more sustainable.
Problem 1: Food Waste in Canteens
Definition of the Problem:
Every day, large amounts of food are wasted in school canteens. Reasons include oversized portions,
students buying food they do not finish, and a lack of awareness about the consequences of food waste.
Edible food often ends up in dustbins instead of reaching those who need it.
Impact:
• Valuable resources such as water, energy, and money are wasted.
• Food waste decomposes to release harmful greenhouse gases like methane, contributing to global
warming.
• Students miss the chance to learn the importance of valuing food.
Solutions:
• Introduce a “Share Table” where untouched food can be placed for others to take.
• Start a composting system for leftover food scraps.
• Offer smaller, flexible portion sizes in the canteen.
• Organize awareness drives such as “Finish Your Plate” campaigns to promote responsible eating
habits.
Problem 2: LED Lighting and Eye Health
Definition of the Problem:
LED lights are widely used in schools because they save electricity. However, the bright white light and high
blue-light content can strain the eyes. Many students experience discomfort after long hours in LED-lit
classrooms without realizing the cause.
Impact:
• Causes eye strain, dryness, headaches, and sometimes difficulty in sleeping.
• Long-term exposure can increase the risk of retinal problems and poor vision.

• Students may lose focus in class due to constant discomfort.
Solutions:
• Use warm white LEDs (under 3000K) that are less harsh on the eyes.
• Install flicker-free, high-quality LED panels with diffusers to reduce glare.
• Arrange classroom lighting layouts to avoid direct glare on students’ eyes.
• Encourage the 20-20-20 rule: after every 20 minutes of reading, look 20 feet away for 20 seconds.
• Introduce curtains or blinds to balance natural and artificial light.
Conclusion
Food waste and harmful lighting may not always be visible problems, but they silently affect the
environment and the well-being of students. Reducing food waste can teach responsibility, save resources,
and reduce pollution. Improving LED lighting systems can protect eye health and create a more comfortable
learning space. By addressing these overlooked issues, schools can take a big step toward creating a
healthier, student-friendly environment.
