According to a group of experts, the level of ozone in the ozone hole has seemingly minimized, still is highest in the past two decades.

The ozone layer's Antarctica hole's NASA satellite images showed that the hole of ozone has remained lower than average of all the past years. The scenario has been seen for the second year in a row.

Yes! It is being said that one year's data is not enough to suggest that the trend of improvement would go on. But, the second smallest hole in past 20 years has been seen by 2012.

The report found that in the 1980s, the ozone layer had turned into a household word. Scientists were keeping an eye on the Antarctica hole's annual appearance for many years. They said that the products that carried chemicals such as CFCs were destroying ozone.

The boffins even said that such products were commonly brought in use for things ranging from paint to a hair spray. These were added as propellants in the spray cans.

Since, numerous chemicals were found showing some link to the reduced ozone and to the increased annual Antarctica hole. Therefore, many developing nations had decided in 1987 to cut the extensive use of the aforementioned products.

Where the EPA urges for strictly controlling consumer and industrial products as reports showed that these increased melanoma risk, NASA denies the same. The agency says that good ozone layer has shown improvement since the 1990s.
