Ozone Hole has Grown in 2008
I just read that the ozone hole over the antarctic is bigger in 2008 than it was in 2007.
In 2008, the ozone hole expanded by 2 million square kilometers to 27 million square kilometers (or 10.4 million square miles).
Despite it’s growth over the last year, the ozone hole still isn’t as large as it was in 2006, when it was the most severe ozone hole on record. Back then it reached 29 million square kilometers (11.2 million square miles) on September 24.
In case you’re wondering, when it comes to the ozone hole, bigger is not better. The ozone protects us from ultraviolet rays that can increase our risk of cancer and harm marine life. The larger the ozone hole becomes, the worse it is for us on Earth.
