Commission for the Conservation of Antarctic Marine Living ResourcesA. OverviewAntarctica is surrounded by an unbroken and dynamic body of water known as the Southern Ocean, which constitutes about 10% of the world's total ocean surface. For about 200 years, Antarctica's resources have been unsystematically harvested. In many cases the intense level of exploitation resulted in the severe depletion of harvested stocks, as was the case for fur and elephant seals in the 19th century, and whales ...

The Montreal Protocol The Montreal Protocol on Substances that Deplete the Ozone Layer is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances (ODS). When released into the atmosphere, those chemicals damage the stratospheric ozone layer, Earth’s protective shield that protects humans and the environment from harmful levels of ultraviolet radiation from the sun.

Here’s a closer look at some of the most popular misconceptions around the climate crisis.

Human activities have had a major effect on the balance of the Antarctic marine ecosystem, this can be seen by damage of large agae such as kelp that is caused by increased UV penetration

By Mario Molina, Nobel Prize Laureate in Chemistry and Durwood Zaelke, President, Institute for Governance and Sustainable Development Ozone depletion was the first human threat to the global atmosphere to be recognized. It was also the first to be addressed by the international community. The results have been truly remarkable. The Montreal Protocol on Substances that Deplete the Ozone Layer, which celebrates its 30th anniversary this year, can claim to be one of the most successful ...

From Antarctica to the high Arctic, what strikes her most is the man-made leftovers she almost certainly finds on the ocean floor. Even the seafloor of Antarctica holds debris like glass liquor bottles, a reminder of the whaling era, for example.

But in 1985, a hole was confirmed in the ozone layer over Antarctica. The world’s natural sun shield, which protects humans, plants, animals and ecosystems from excessive ultraviolet radiation, had been breached.

The recent collapse of a 1,100km 2 ice shelf in Antarctica came at a time of record high temperatures and is a symptom of a planet in climate crisis, experts say. The Conger ice shelf, which cleaved away from the eastern side of Antarctica in March, is the latest victim of rising temperatures at the ...

Ecosystem management Ecosystem management focuses on sustaining and restoring ecosystem health while balancing ecological, economic and social needs. By recognizing the interconnectedness of natural systems and human activities, the integrity and resilience of ecosystems can persevere in the face of challenges like climate change, habitat degradation and over-exploitation. This approach is important to ensure the continued and sustainable provision of essential services, like clean water and ...

Portable sewage tanks for treating wastewater are giving floating villages in Sabah access to sanitation, with hopes the technology can be expanded across the country.
