Ocean Acidification and Marine Sustainability

The video discusses UN Sustainable Development Goal 14, focusing on conserving oceans and marine resources. It highlights the challenges of marine pollution, particularly plastic waste, and its impact on marine life. The video also covers ocean acidification due to carbon emissions and the importance of sustainable fishing practices. Solutions such as reducing single-use plastics and promoting sustainable seafood sourcing are proposed. Achieving SDG 14 requires global efforts to rebuild marine ecosystems and reduce human pressures.

What is the main goal of the UN Sustainable Development Goal 14?

• To eliminate all forms of marine pollution

• To conserve and sustainably use oceans, seas, and marine resources

• To increase the number of marine protected areas

• To reduce the global carbon footprint

How much plastic enters the oceans each year?

• 5 million metric tons

• 10 million metric tons

• 12 million metric tons

• 8 million metric tons

Which marine species are particularly vulnerable to plastic pollution?

• Dolphins and sharks

• Seabirds like albatross and petrels

• Coral reefs

• Sea turtles and jellyfish

What is a simple way to reduce single-use plastic consumption?

• Replacing plastic bags with reusable bags

• Recycling all types of plastics

• Avoiding all packaged goods

• Using paper bags instead of plastic bags

What percentage of plastic bottles are recycled?

• 40%

• 80%

• 20%

• 60%

What is ocean acidification primarily caused by?

• Oil spills in the ocean

• Dissolution of carbon dioxide into seawater

• Excessive fishing activities

• Increased levels of nitrogen in the water

Why is ocean acidification a threat to marine life?

• It increases the water temperature

• It reduces the oxygen levels in water

• It causes coral bleaching

• It hinders the ability of marine organisms to form shells

What is a key practice to ensure sustainable fishing?

• Avoiding all seafood

• Checking for Marine Stewardship Certification

• Buying imported fish

• Fishing in protected areas

What does the Marine Stewardship Certification (MSC) label indicate?

• The seafood is organic

• The seafood is free of microplastics

• The seafood is locally sourced

• The seafood is from a sustainable fishery

What is necessary to achieve Sustainable Development Goal 14?

• Increasing the number of marine species

• Reducing the number of marine protected areas

• Rebuilding marine life and reducing pressures

• Complete elimination of all marine activities
