“The hole in the Earth’s ozone layer, once the most feared environmental peril facing humanity, is set to be completely healed over most of the world within two decades following decisive action by governments to phase out ozone-depleting substances, a new UN assessment has found.” as reported by Oliver Milman in The Guardian on 9th January 2023.
We asked Roberta for her comments on this news.
“The Montreal Protocol, which was signed in 1987, was actually successful. You know, there was scientific evidence, that these ozone depleting chemicals that we were releasing in the atmosphere were eroding the important ozone layer.
We had all the parties coming together signing this protocol in Montreal, for phasing out these ozone-depleting substances. Now that nearly 90% of these chemicals are banned, the protocol has succeeded to safeguard the ozone layer.
So, you know, this is an example of how the world came together to solve this problem, and succeeded. So, let’s take this as an example for climate change and biodiversity loss as we can do it together.”
“We have the will. This is such good news, because this scientific assessment that came out yesterday, says that the ozone layer is on track to recover within the next four decades. And this is such important news, because, you know, this ozone layer in the upper stratosphere, helps to ban the harmful ultraviolet rays from the sun.
So the science was there, they produce the evidence, the countries realize this is important, and they started to phase out these chemicals. And now, we are recovering. Nature is doing its work and is recovering the layer. It is a very good example of what we collectively can do, and just remember, we just have a one world where we live, we don’t have a planet B. So, you know, this is the only way to go.”
