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 “while 2018 was a challenging year, we saw hope in growing action. 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 remarkable story of the battle to save the ozone layer starts with science
At that time, they didn’t know the scale of the problem 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. We work to protect and restore coastal ‘blue carbon’ ecosystems for the sustainable provision of ecosystem services to people and environment
Mangroves and seagrass meadows are coastal ecosystems that cover a small portion of the total ocean area but collectively are widely distributed on every continent except antarctica Mangroves are found in 123 countries worldwide with an estimated area of 15.2 million hectares while seagrasses occur in 159 countries covering over 30 million. Unep is the global champion for the environment with programmes focusing on sustainable development, climate, biodiversity and more. Some researchers believe the outbreak is a sign of things to come
As climate change rapidly warms the artic, scientists say it could unleash a wave of potentially deadly microbes that for centuries have been trapped in ice.
Examining novel technologies such as geoengineering for the first time, the panel warns of unintended impacts on the ozone layer. 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. In 2023, the world saw new highs of greenhouse gas emissions, temperature records tumbling and climate impacts arriving stronger and faster At the same time, most of the sustainable development goals (sdgs) were off track at the halfway point of the 2030 agenda for sustainable development.
Un environment released its 2018 annual report, highlighting the organization’s work on issues from fighting pollution of the air and sea to helping nations meet their goals of reducing greenhouse gas emissions
