In the 80s and 90s, scientists discovered a huge hole in the ozone layer over Antarctica. They quickly realized that this was caused by human activities, such as the use of aerosols and CFCs. Luckily, it looks like we're on our way to solving this problem! Scientists say the hole is closing, and they credit the Montreal Protocol for helping us get there. What is this for our planet? And what can we do to continue making progress? Check out this blog post to find out!
It could be the first good news for the environment and for the Earth for many years now. The hole in the ozone layer is a long-standing problem that seemed impossible to resolve. Recently, however, considering density, concentration and extension of the ozone area, the picture has improved a lot, probably thanks to the Montreal Protocol, the international treaty signed by an increasing number of nations.
A treaty against the hole in the ozone layer
Il document it was presented almost thirty years ago, and aimed at banning the use of the chemical substances responsible for the destruction of gas. The ozone hole was discovered in 1985.
The ratification of the protocol has so far taken place in 192 countries and will lead to the total ban on the substances indicated by 2030. Already now, however, we have obtained a great result, according to what researchers from MIT and the University of Leeds say: the thinning of the ozone layer has started to reverse its course and the positive trend is therefore close.
The hole in the ozone layer will therefore close and return to "normal" by 2050. The positive effects will fall on all of us.
