The Antarctic Ocean Alliance (AOA) has called for the protection of 3.6 million square kilometres of ocean, which would include a large proportion of the Ross Sea and create a reserve comparable in size to Australia. The reserve would be protected from fishing and development, and would form part of a network of 19 protected areas in the Southern Ocean around Antarctica, helping to preserve the region’s unique wildlife. The oceans around Antarctica are some of the most pristine in the world, and are still relatively untouched by human activities. In particular, the Ross Sea remains the most intact marine ecosystem on the planet. The waters around Antarctica are home to almost 10,000 species, many of them found nowhere else. The Ross Sea still retains large populations of all its top predators, and supports many of Antarctica\'s most charismatic species, including emperor penguins, Antarctic minke whales, Weddell seals and Antarctic petrels. However, Antarctica\'s unique environment faces a range of threats, including overfishing and the effects of climate change. Broader approach needed Both New Zealand and the United States have already proposed reserves for the Ross Sea. However, the AOA claim that a much larger protected area is needed. \"The Ross Sea is one of the most amazing and relatively untouched marine environments on Earth,\" said Chuck Fox of the AOA. \"While there are two proposals on the table to protect some of it, our report shows that we need a much broader and ecosystems-focused approach if we are to ensure this environment remains healthy and stable.\"
