BBC Blue Planet 2

What are the main threats to coral reefs?

• Overfishing, pollution, and climate change

• Nuclear war, zombie apocalypse, and robot uprising

• Deforestation, desertification, and soil erosion

• Alien invasion, volcanic eruption, and asteroid impact

Name one deep sea creature featured in Blue Planet 2 and describe its unique adaptation to the deep sea environment.

• Anglerfish - They have wings to fly in the deep sea

• Jellyfish - They have a skeleton to protect them from the pressure of the deep sea

• Squid - They have the ability to breathe air in the deep sea

• Giant tube worms - They have a symbiotic relationship with chemosynthetic bacteria, allowing them to survive in the extreme conditions of the deep sea.

Explain the concept of a marine ecosystem and provide an example of one featured in the series.

• Freshwater lake ecosystem

• Arctic tundra ecosystem

• Coral reefs

• Desert ecosystem

Why is ocean conservation important and what are some initiatives highlighted in Blue Planet 2?

• To protect marine life and ecosystems, and initiatives include reducing plastic pollution, creating marine protected areas, and promoting sustainable fishing practices.

• To conserve freshwater resources and initiatives include increasing plastic pollution, reducing marine protected areas, and promoting unsustainable fishing practices.

• To protect land animals and ecosystems, and initiatives include planting more trees, building wildlife reserves, and promoting hunting practices.

• To promote industrial fishing and initiatives include increasing plastic pollution, reducing marine protected areas, and promoting unsustainable fishing practices.

Describe one underwater filming technique used in Blue Planet 2 and how it enhances the viewer's experience.

• Using CGI to create underwater scenes

• The use of hot air balloons for aerial shots

• The use of underwater drones

• Filming with a handheld camera from a boat

What are the key characteristics of coral reefs and why are they considered important ecosystems?

• Key characteristics of coral reefs include being small in size, having no impact on marine life, and being easily replaceable. They are not important ecosystems because they do not contribute to the biodiversity of the ocean.

• Key characteristics of coral reefs include high biodiversity, complex structure, and reliance on symbiotic relationships. They are important ecosystems because they provide habitat for numerous marine species, protect coastlines from erosion, and support local economies through tourism and fisheries.

• Key characteristics of coral reefs include being made of rocks, having no marine life, and being irrelevant to the ecosystem. They are not important ecosystems because they do not provide any benefits to the environment.

• Key characteristics of coral reefs include low biodiversity, simple structure, and no reliance on symbiotic relationships. They are not important ecosystems because they do not provide habitat for marine species, do not protect coastlines from erosion, and do not support local economies through tourism and fisheries.

Name one deep sea creature that relies on bioluminescence for survival and explain how it uses this adaptation.

• Jellyfish

• Sea turtle

• Anglerfish

• Octopus

Discuss the impact of human activities on marine ecosystems and provide examples from Blue Planet 2.

• Human activities have led to overfishing, pollution, and climate change, impacting marine ecosystems. For example, the show Blue Planet 2 highlights the devastating effects of plastic pollution on marine life.

• Climate change has no effect on marine life

• Human activities have no impact on marine ecosystems

• Marine ecosystems are not affected by pollution

How does the series highlight the interconnectedness of marine life and the importance of preserving ocean habitats?

• The series showcases the interconnectedness of marine life through its storytelling and visuals, emphasizing the importance of preserving ocean habitats.

• The series only highlights the interconnectedness of marine life but does not emphasize the importance of preserving ocean habitats.

• The series has no emphasis on the interconnectedness of marine life and the importance of preserving ocean habitats.

• The series focuses on the dangers of marine life and the irrelevance of preserving ocean habitats.

Explain the challenges of filming underwater and how the crew overcame them to capture stunning footage for Blue Planet 2.

• Specialized underwater cameras, new filming techniques, and communication devices

• Using traditional land cameras

• No challenges, filming underwater is easy

• Using drones for aerial shots
