Explanation / Answer
2) I think all the options are correct because increase of the temperatures due to global warming results in the melting of ice so that the arctic animals will die especially polar bears.Because increase in temperature will also leads to the death of seals.They mainly eat ringed seals and bearded seals.Without food polar bears cannot sustain and they may invade to land masses as the ice caps starts melting.This migration will leads to the death of polar bears as they cannot survive in high temperature areas when they starts migration from ice to land masses.
3) I think South America is the continent which streches to the antarctica will receive more amount of UVB rays and this is due the "OZONE HOLE" in that region.As we all well known that we are completely protected from UV rays by ozone layer and if that layer damages,obviously the UV rays will fall on particular land mass which leads to many disastorous factors.
