Ozone layer may be restored in decades, UN report says

오존층을 보호하기 위한 인간의 조치는 효과가 있었고, 수십 년 안에 회복될 수도 있다고 유엔은 1987년 오존층을

손상시키고 있는 유해한 화학물질의 사용을 중단하기로 한 국제 협약이 성공적이었다고 말했습니다.

오존층은 태양으로부터 오는 자외선의 대부분을 흡수하는 지구 대기의 얇은 부분입니다.

그것이 고갈될 때, 이 방사선은 표면에 도달할 수 있고 인간과 다른 생물들에게 잠재적인 해를 끼칠 수 있습니다.

Now to an International report which says that Human Action to save the ozone layer appears to have worked the study says it should fully recover within decades as Naomi Choi Smith now reports.

Naomi Choi Smith: The ozone layer, a thin shield that protects us from the sun's harmful ultraviolet rays damaged and depleted by chemicals released into the atmosphere now finally some good news the ozone layer is healing and could be fully restored in the next four decades That's according to a new report co-authored by the UN us and EU which says Human Action to ban ozone harming chemicals is working.

Stephen Duharric: The phase out of nearly 99% of banned ozone depleting substances has succeeded in safeguarding the ozone layer leading to notable recovery of the ozone layer in the upper tratosphere and decrease human  exposure to harmful ultraviolet rays from the Sun

Naomi Choi Smith: Poles were first discovered in the ozone layer in the 1980s By 1987 46 countries had signed up to the Montreal protocol Banning gases in aerosols and fridges called CFCs They were destroying the ozone leading through harmful ultraviolet rays that can cause problems like skin cancer but while the depletion of ozone is not a major cause of climate change. Saving the ozone layer does have a positive knock-on effect on global warming because some of the chemicals that were phased out are powerful greenhouse gases. The report says the ozone layer should recover to 1980 Levels by roughly 2066 over the Antarctic by 2045 over the Arctic and by 2040 for the rest of the world. There's always the risk that progress could be reversed. still the UN is optimistic saying this sets a good example for other environmental action. as the battle for our planet's future isn't over yet .​
