SCIENCE: CURRENT EVENT 5

Did you know that Earth is surrounded by ozone, a layer of gas that protects the Earth from harmful UV rays. Usually, all the time, the amount of ozone in each area is different at different times. Scientist, till now recorded the amount of ozone particularly the North Pole. It decreases and it increases but scientist have never seen the amount of ozone this low. Normally there is the most amount of ozone in the area of the Arctic Circle. But according to the record that they have recorded till now, few days ago, scientist have found out that early spring of 2011, the amount of ozone near the North Pole was way too low to say that it was a slight change in the amount of ozone. This way, scientists are worrying that there won't be enough ozone to protect the Earth from the sun's powerful UV rays. They have seen such happenings in the southern hemisphere but they have never seen such happenings near the North Pole. They call this the 'Arctic ozone hole' even though it does not have a full hole in it, it is so close for being a hole, the scientists call it that way. But they sill don't know if it is a slight change in the atmosphere or if its a loss of the ozone.
