Note to Pupils:

Advantages of a Healthy Environment:

1. Clean air and water: A healthy environment provides clean air to breathe and safe water to drink. Clean air is essential for respiratory health, while safe drinking water prevents waterborne diseases. This leads to a higher quality of life and reduced healthcare costs.
2. Biodiversity: A healthy environment supports a diverse range of plant and animal species. This biodiversity is crucial for ecosystem stability and resilience. It ensures the survival of various species and promotes genetic diversity, which can be essential for adapting to environmental changes.
3. Improved quality of life:
4. Protection of human health.
5. Sustainable resources: A healthy environment promotes the sustainable use of natural resources, such as forests and fisheries. It ensures that these resources are available for future generations, supporting industries and livelihoods.
6. Climate Regulation: Healthy ecosystems help regulate the climate by absorbing and storing carbon dioxide and releasing oxygen. This natural balance is essential in mitigating climate change, which can have catastrophic consequences on a global scale.
7. Recreational and Aesthetic Value: A pristine environment provides opportunities for recreation and relaxation. It offers scenic beauty, clean parks, and open spaces that contribute to physical and mental well-being.

Disadvantages of Degrading Environments:

1. Pollution:Degrading environments can result in air and water pollution, leading to health problems in humans and wildlife. Polluted air can cause respiratory diseases, while polluted water can contaminate drinking sources and harm aquatic life.
2. Loss of biodiversity: Environmental degradation often leads to the loss of plant and animal species. Habitat destruction, pollution, and climate change can drive species to extinction, disrupting ecosystems and reducing biological diversity.
3. Adverse health effects.
4. Resource depletion: The unsustainable use of natural resources, such as deforestation and overfishing, leads to their depletion. This not only affects the availability of these resources but can also lead to economic losses and reduced job opportunities.
5. Climate change: Environmental degradation contributes to climate change, resulting in more frequent and severe extreme weather events, including hurricanes, droughts, and floods. These events can cause damage to infrastructure, agriculture, and human settlements.
6. Loss of Aesthetic Value and Quality of Life: A degrading environment can diminish the aesthetic value of natural landscapes. This loss of beauty can impact the well-being of individuals and communities, as it reduces opportunities for recreational activities and the enjoyment of nature.

Evaluation:

1. List 4 advantages of a healthy environment.
2. List 3 disadvantages of degrading environments.
