CLEAN : Hungry penguins chase Antarctics shifting krill

The video discusses the critical role of krill as a keystone species in the Antarctic ecosystem, supporting various marine life such as whales and penguins. It introduces the ECHO harvesting method for sustainable krill fishing, minimizing environmental impact and avoiding bycatch. The importance of taking responsibility for sustainability, especially when in the majority, is emphasized. The video also highlights the significance of maintaining intact marine ecosystems, despite historical whaling activities. The session concludes with a brief interruption.

Why is krill considered a keystone species in the Antarctic ecosystem?

• It is the largest species in the Antarctic.

• It is a primary food source for many animals.

• It is the only species that can survive in extreme cold.

• It helps in regulating the temperature of the ocean.

What is the main goal of the ECHO harvesting method?

• To increase the population of krill.

• To eliminate the need for human intervention in krill fishing.

• To fish for krill without harming other species.

• To reduce the cost of krill fishing.

How does ECHO harvesting minimize environmental impact?

• By ensuring no other species are caught during krill fishing.

• By using larger nets to catch more krill.

• By fishing only during the winter months.

• By using automated fishing techniques.

What is a significant feature of the Antarctic marine ecosystem mentioned in the video?

• It is the only ecosystem where krill are found.

• It is the most diverse ecosystem on the planet.

• It remains largely intact despite past whaling activities.

• It has been completely destroyed by whaling.

Why is it important to maintain intact marine ecosystems?

• They are the primary source of oxygen for the planet.

• They support diverse food webs crucial for survival.

• They are the only source of fresh water.

• They prevent global warming.
