This is one of the most effective environmental agreements to date. This Montreal Protocol started out as an international pact to safeguard the ozone layer. United global effort to phase out pollutants that deplete ozone means that nowadays the ozone layer hole cures human health, economies and ecosystems. It’s a healthy and safe environment. However, the Montreal Protocol achieves much more than the World Ozone Day this year aims to emphasize — slowing climate change and contributing to enhancing energy effectiveness in the cooling industry that adds to food safety.
