What is the greatest threat to Antarctica?

What is the greatest threat to Antarctica?

Threats

• Climate change. Climate change is the greatest long-term threat to the region.
• Increased fishing pressure and illegal fishing.
• Marine pollution. Persistent organic pollutants (POPs) have been measured around Antarctica and detected in wildlife.
• Invasive species.

What are future threats to Antarctica?

Tourism, mining, fishing and bioprospecting are just four activities that could threaten the sustainability of Antarctica in the future. All of these interests have the potential to damage, change or destroy Antarctica and its surrounding oceans if not carefully controlled, managed or banned.

How are humans destroying Antarctica?

Global warming, ozone depletion and global contamination have planet-wide impacts. These affect Antarctica at the largest scale. Fishing and hunting have more localised impacts, but still have the potential to cause region-wide effects.

Why is Antarctica a dangerous place?

Winter temperatures plummet to about -100 degrees Fahrenheit, and that, combined with the world’s driest air, makes it a struggle to even climb a flight of stairs. The air causes instant pain to any exposed skin. It’s not even wise to smile—your gums and teeth will ache. Frostbite can set in quickly.

Can you go to Antarctica without permission?

No country owns Antarctica, instead, all activities are governed by the Antarctic Treaty of 1959 and associated agreements, referred to collectively as the Antarctic Treaty System. If you are a citizen of a country that is a signatory of the Antarctic Treaty, you do need to get permission to travel to Antarctica.

Why is Antarctica so fragile?

The collapse of the Larsen C ice-shelf is a reminder that Antarctica and the Southern Ocean are very fragile environments, with the land, waters and marine life increasingly impacted by the effects of climate change. As ice shelves collapse the glaciers behind them retreat more quickly, causing further sea-level rise.

What will happen to Antarctica in the next 50 years?

These glaciers will add to sea-level rise if they melt. The temperature of Antarctica as a whole is predicted to rise by a small amount over the next 50 years. Any increase in the rate of ice melting is expected to be at least partly offset by increased snowfall as a result of the warming.

Why tourists should not be allowed in Antarctica?

Tourists, along with research scientists, may unknowingly bring seeds and spores of plants from other areas. There is the threat of pollution, eg oil spills from the cruise ships and other methods of transport.

Can you breathe in Antarctica?

The air is so cold that it’s dangerous to breathe it directly. The dense, cold air slid down the slopes and got trapped in small depressions in the ice.

Is the C silent in Antarctica?

The words Arctic, Antarctic and Antarctica were originally pronounced without the first /k/, but the spelling pronunciation has become very common. The first “c” was originally added to the spelling for etymological reasons and was then misunderstood as not being silent.

Has anyone been born in Antarctica?

Eleven babies have been born in Antarctica, and none of them died as infants. Antarctica therefore has the lowest infant mortality rate of any continent: 0%. What’s crazier is why the babies were born there in the first place. These weren’t unplanned births.

Which is the greatest danger that faces Antarctica?

The greatest danger which faces Antarctica is the possible exploitation of its mineral wealth and oil and coal reserves. Since 1961 Antarctica has been protected by an international treaty which only allows scientific bases to be established on the continent.

How is fishing a threat to the Antarctic?

Fishing: There is a danger that krill and other small fish will be over fished and that mean a huge danger for all the animals in the Antarctic. Krill provide food for nearly every sea animal and if they are over fished then the other will starve.

How are rats a threat to the environment in Antarctica?

Rats in particular are a potential threat to Antarctica’s ground nesting birds on sub-Antarctic islands which are particularly vulnerable as there are no native ground based predators for them to be experienced in defending themselves against.

Do you have to wear eye protection in Antarctica?

That’s snow blindness, and it’s a real risk in Antarctica. We have to wear good eye protection whether the day’s cloudy and overcast or bright and sunny; either way, the snow and ice reflect sunlight to a dangerous degree for eyes. Snow blindness can even occur during a snow storm if the cloud cover is thin.
