Introduction

Celebrate World Ozone Day on September 16 by learning about the importance of protecting ozone layer and taking action to protect it! This day was established to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer, which was signed in 1987. Since then, more than 200 countries have come together in an effort to reduce their use of ozone-depleting substances and take part in activities that help protect our planet's atmosphere from further damage.
