Aquaponics: A Sustainable Future

What is the primary focus of the video on aquaponics?

• The history of aquaponics

• The economic impact of aquaponics

• Aquaponics as a sustainable fish farming method

• Aquaponics in urban gardening

What global issue is contributing to the need for aquaponics?

• Abundance of freshwater resources

• Decreasing urban populations

• Urban sprawl reducing farmland

• Increasing global fish populations

How does aquaponics differ from traditional fish farming?

• It requires more water than traditional methods

• Fish waste is recycled as plant food

• It uses soil for plant growth

• Fish waste is disposed of

What role do beneficial bacteria play in an aquaponics system?

• They provide nutrients directly to fish

• They break down fish waste into plant food

• They increase the water temperature

• They remove oxygen from the water

What is a crucial factor in maintaining healthy beneficial bacteria in aquaponics?

• Using chemical fertilizers

• Adding more fish to the system

• Maintaining a neutral pH balance

• Increasing water temperature

Why might aquaponics be considered a cost-effective method of food production?

• It relies heavily on chemical inputs

• It is only suitable for large-scale operations

• It uses less water and no pesticides

• It requires expensive synthetic nutrients

Which of the following is NOT a benefit of aquaponics?

• Protects ocean fish populations

• Reduces habitat destruction

• Provides a sustainable food source

• Increases urban sprawl

What is a key advantage of aquaponics in drought-prone areas?

• It requires large amounts of water

• It can grow food with minimal water

• It is not suitable for dry climates

• It relies on rainwater harvesting

Which type of fish is commonly used in aquaponics systems?

• Shark

• Tilapia

• Goldfish

• Salmon

What is the main environmental benefit of aquaponics?

• Decreases biodiversity

• Increases soil fertility

• Reduces water usage

• Increases carbon emissions
