= What is the impact of people both those living in Antarctica and the world’s population on Antarctica? = == Think about changing sea levels, melting ice shelves, over-fishing, waste management of human wastes, waste management in general (rubbish and recycling), ==

‍ What can be done to reduce these impacts?

Ocean acidification is a consequence of rising global carbon dioxide levels to have serious consequences for cold-water ecosystems, including cold-water corals. Rising levels.They will upset the balance of carbonate ions, making it difficult for some organisms, which have composed, to form their shells. Many of the organisms that are affected, and are predicted to be affected, are critical for ecosystem health.

The process of ocean acidification involves several steps. in the air above the sea surface constantly dissolves and forms carbonic acid. Carbonic acid can break up into hydrogen ions and bicarbonate ions.



POPULATION ON ANTARCTICA

Antarctica population is very difficult to account since the number is so small and varies during the year Antarctica has a permanent human population of zero. Antarctica's population is made up entierly of researches and scientists from around the globe. About 1,000 scientific personnel live there during the winter and this population increeses to about 5,000 during the Antarctic summer. . The first semi permanent population of Antarctica region was the British and the Americans who did spent more than a year in South Georgia.



GLOBAL WARMING

Global warming is the warming up of the planet above the temperature it should be. It is such a concern at the moment as it seems that the temperature is rising at a rate far faster than ever before. That it may be be the activites of the human population over the last 150 years or so that is doing it.

Tempretures over the past have risen by about 0.74 C in the last 100 years. More then half of this increese has happend in the last 25 years.this is a worry because while the planet can cope with changes in temperature which is known to have happened over periods of thousands of years in the past and certainly over millions of years.

The current rate of change is much, much faster than any changes have ever before
