Lots of people who aren't scientists go to Antarctica. V. Tourist visits to the Antarctic have to be carefully monitored and organized so they don't damage fragile vegetation, disturb nesting grounds or pollute. Now that more and more people go to Antarctica, there's even greater chance damage could occur. Most of the people who visited Antarctica the early days were explorers. The permanence of snow and ice in the Arctic and Antarctic is what makes these regions unique.
Temperatures are low at all times partially because snow reflects the sun rays.
Humans whale hunting in the past caused krill and fur seals to increase in numbers, upsetting the balance of existing food webs. The ultraviolet light coming through the ozone holes can stop phytoplankton from growing, so the krill have less to eat. Antarctica is 5,400,000 square miles in area, and that's as big as the U.S. and Mexico combined. Antarctica is very hard to get to because of weather, sea ice, and it is so far away from where most people live. Also, it is dark for six months every year.
