The video discusses the significance of wetlands and mangroves, highlighting their ecological roles such as supporting fisheries, protecting coastlines, and storing carbon. It addresses threats like pollution, commercial development, and climate change, and suggests solutions including sustainable practices and education to conserve these vital ecosystems.

What are wetlands primarily characterized by?

• Water covering the soil

• Desert conditions

• Dry soil

• Mountainous terrain

Which type of wetland is known for its unique root system?

• Mangroves

• Bogs

• Swamps

• By providing a habitat for large predators

What role do mangroves play in coastal protection?

• They block sunlight from reaching the coast

• They cause coastal erosion

• By reducing industrial waste

• By clearing land for agriculture and shrimp farming

What impact does climate change have on mangroves?

• It decreases sea levels

• It increases salinity and sea levels

• It reduces the amount of sunlight

• It stabilizes temperatures

Which practice is suggested for sustainable shrimp farming?
