QUESTIONS TO ANSWER IN YOUR REPORT:
• What is awetland?
• What does awetland do for the environment?
• What does awetland do for plants and animals?
• What does awetland provide for humans?
• What are the environmental dangers that wetlands face?
• Choose a specific wetland and assess the habitats,
biodiversity and water quality of this wetland.
• What would the impact be to biodiversity and water quality if
this wetland was lost?
Wetlands should be protected because:
• they are natural water-purification systems;
• they act like sponges to store water in the wet season and
supply water in the dry season; and
• they slow down flood water to prevent damage to property
and the environment.
KEY CONCEPTS
• Clean water is vitally important to ensure the health of
humans, animals and plants.
• Water can be polluted by insoluble substances, soluble
substances and disease-causing germs.
• Wetlands act as natural water purifiers because they can
absorb soluble and insoluble impurities from water and they
regulate water flow across the landscape.
