The earth's protective ozone layer is finally healing from damage caused by aerosol sprays and coolants, a new United Nations report said. The ozone layer had been thinning since the late 1970s. Scientist raised the alarm and ozone-depleting chemicals were phased out worldwide.
Cut-price Chinese home insulation is being blamed for a massive rise in emissions of a gas, highly damaging to the Earth's protective ozone layer. The Environmental Investigations Agency (EIA) found widespread use of CFC-11 in China, even though the chemical was fully banned back in 2010.
The decline in the atmosphere of an ozone-depleting chemical banned by the Montreal Protocol has recently slowed by half, suggesting a serious violation of the 196-nation treaty, researchers revealed Wednesday.
