Step 1
Threats from Fishing: Overfishing of Krill
Answer
Fishing activities in the Southern Ocean have led to the overexploitation of krill, which is a crucial food source for many marine species, including whales, seals, and penguins. With krill populations declining, the entire food web is jeopardized, potentially leading to significant ecological imbalances.
Step 2
Threats from Fishing: Disruption of Marine Ecosystems
Answer
Industrial fishing practices can lead to the destruction of habitats, particularly through trawling, which disturbs the seabed and the ecosystems it supports. This disruption can have long-term effects on biodiversity and the overall health of oceanic ecosystems around Antarctica.
