Antarctica’s Biodiversity at risk, Emperor Penguins could be extinct by 2100

Antarctica’s Biodiversity at risk:

Antarctica’s Biodiversity new research has indicated that more has to be done to safeguard Antarctic ecosystems, and if we don’t make a change, up to 97% of Antarctic species with land-based populations might go extinct by the year 2100. The study, which was just released, also discovered that ten crucial techniques to lessen threats to Antarctica’s biodiversity may be implemented with just USD 23 million annually.

Antarctica’s Biodiversity at risk: Key Points

  • Up to 84% of the terrestrial bird, animal, and plant groups would gain from this very tiny sum.
  • The distinctive plant and animal species of Antarctica are most at risk from climate change, according to our research.
  • The best approach to ensure their future is to reduce global warming.
  • Threats to Antarctic biodiversity Land-based species in Antarctica have evolved to thrive on Earth’s coldest, windiest, highest, and driest continent.

Antarctica’s Biodiversity

  • Numerous microorganisms, tough invertebrates, two flowering plants, hardy moss and lichens, two flowering plants, and hundreds of thousands of nesting seabirds, including emperor and Adélie penguins, make up the species.
  • Additionally, Antarctica offers the world and humanity priceless benefits. By driving ocean currents and air circulation, as well as absorbing heat and carbon dioxide, it influences the global climate.
  • Even Australia’s weather is influenced by Antarctica.

What is causing Antarctica ice melt?

It is expected that Antarctica’s ice-free areas would grow as global warming becomes worse, drastically altering the wildlife habitat. The vegetation and fauna of Antarctica are anticipated to suffer as extreme weather events like heat waves increase in frequency.

Additionally, the yearly influx of scientists and visitors might damage the environment by polluting and uprooting plants and other natural resources. Additionally, Antarctica’s milder climate and increased human tourism foster an environment that is favourable for the growth of invasive species.

Could Antarctica’s Emperor Penguin be Extinct by 2100?

  • If present conservation efforts continue on their current course, the populations of 97% of Antarctic terrestrial species and breeding seabirds might potentially drop between now and 2100.
  • 37% of the species’ populations would, at best, decline. By 2100, 65% of the plants and animals on the continent are expected to disappear.
  • The emperor penguin is the most endangered species in Antarctica because it breeds on ice.
  • The emperor penguin is the only species in our analysis that, in the worst-case scenario, faces extinction by 2100.

Other Antarctic specialities like the nematode worm Scottnema lindsayae are also predicted to suffer adverse effects from climate change. The species, which inhabits moisture from soils, due to warming and ice-melt since it thrives in extremely dry soils.

Why does Antarctica have no population?

There are no regular passenger flights to Antarctica because of the rough terrain, severe weather, and lack of a permanent population. Most flights are used to supply the bases and transfer research staff. In the event of an emergency, recovering a stranded aircraft is challenging due to a lack of infrastructure.

All things considered, it is improbable that we will be able to establish long-term human settlements there that are supported by agriculture or animals in the near future. But the climate in Antarctica is already shifting. The ecosystem of the continent is changing, according to Chown, as average global temperatures rise.

Who lives in Antarctica?

Gondwana, a bigger land mass that formerly covered the south pole and split from Australasia and South America long before humans arose, included the Antarctic continent. Since around 35 million years ago, Antarctica has been an isolated island without any land connections. According to geological theory, humans are believed to have very recently emerged in East Africa (no more than 5 million years at most). After that, we departed from the family house and travelled to every continent in the world.

For prehistoric peoples to find, Antarctica was already too remote due to its distance, climate, and choppy seas. It wasn’t until 1820 that navigational techniques and human technology advanced to the point that anyone could sail far enough south to even have their first glimpse of Antarctica. Several ill-founded claims that people first stepped foot on the Antarctic continent as early as 1820 exist, however some historians regard the year 1899 as the undisputed first landing. There wasn’t any wildlife when the first people arrived in Antarctica.

United Nations’ COP15 Action Plan for Antarctica

  • This week saw the conclusion of the COP15 UN summit on nature in Canada. One of the primary agenda items was funding for conservation projects.
  • Such conservation, at least in Antarctica, is surprisingly affordable. According to our research, implementing all measures simultaneously could only cost USD 23 million annually until 2100 (or about USD 2 billion in total).
  • In contrast, it is anticipated that recovering vulnerable species in Australia will cost more than USD 1.2 billion annually (although this is far more than is actually spent).
  • However, we only factored in the cost of lobbying for policy change for the “impact external policy” option (related to mitigating climate change). We did not account for or compare the global costs of decreasing carbon emissions to the far higher economic costs of doing nothing.
