Antarctic: Evaluation of Strategies
Geography: Cambridge International GCSE (2027 Exams), topic 3.2.2
Managing Threats to the Antarctic Ecosystem
International agreements and environmental surveys manage threats to the Antarctic ecosystem, ensuring its protection and sustainable use.
Threats to the Antarctic ecosystem
- The Antarctic ecosystem faces threats from climate change, fishing, and pollution.
- Climate change affects ice habitats and food chains in the Antarctic ecosystem.
- Overfishing can reduce important species, disturbing the Antarctic ecosystem balance.
- Pollution from ships and research stations harms Antarctic wildlife and habitats.
International agreements protecting Antarctica
- The Antarctic Treaty (1959) regulates all activities to preserve Antarctica for peaceful and scientific use.
- The Protocol on Environmental Protection (1991) bans mining and enforces strict environmental rules.
- The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR, 1980) manages fishing to protect marine life.
- These agreements unite countries to ensure the Antarctic ecosystem remains protected.
Environmental impact surveys
- Environmental impact surveys assess the potential harm of human activities on the Antarctic ecosystem.
- Surveys help guide decisions on where and how research or tourism can take place.
- These surveys prevent damage to wildlife and habitats in the Antarctic ecosystem.
- These surveys promote careful planning and minimise disruption to the Antarctic ecosystem.
Sustainable management techniques
- Sustainable fishing limits protect species and maintain the Antarctic ecosystem's food web.
- Strict waste management at research stations reduces pollution in the Antarctic ecosystem.
- Controlled tourism limits visitor numbers and protects breeding colonies in the Antarctic ecosystem.
- Monitoring and scientific research improve understanding and management of the Antarctic ecosystem.
Evaluation of management strategies
- International agreements provide a strong legal framework for the Antarctic ecosystem's protection.
- Environmental surveys help avoid harmful activities, benefiting the Antarctic ecosystem long term.
- Challenges remain due to illegal fishing and climate change affecting the Antarctic ecosystem.
- Continued global cooperation is essential to sustain and protect the Antarctic ecosystem.
