The ozone hole was found by a scientists in University of Waterloo, Canada. The discovery has led to fresh concerns among environmentalists.
Scientists have discovered a large hole in ozone gas layer, which envelops the Earth and protects it from the Sun's harmful ultraviolet rays. The hole is located in the lower stratosphere and is seven times bigger than the one over Antarctica, according to a paper published in AIP Advances.
The newly-discovered all-season hole sits over the tropics and has been there for more than 30 years, said Qing-Bin Lu, a scientist from the University of Waterloo in Ontario, Canada, who made the discovery.
The ozone hole is not technically a "hole" where no ozone is present, but is actually a region of exceptionally depleted levels of the gas, according to American space agency NASA.
