Humans were once on track to destroy Earth’s ozone shield. Collective action averted disaster. Global warming demands the same global cooperation.

We’re all frustrated at the inability of governments to take necessary measures to tackle climate change. Drastic actions are needed, such as putting an end to fossil fuels and setting a price on carbon.

COP26 gave us hope for our future, but we are still far from where we need to be. We might feel that this ecological crisis is impossible to stop.

But in the midst of despair, we can reflect on how our determination in the recent past to improve our standard of living triggered what could have ended in a global catastrophe. Instead, the potential crisis was dealt with by bringing the world together.

In this video, we will introduce you to ozone depletion — which almost led to disaster — in an easy and interesting way. You’ll see that attaining ecological stability is achievable with knowledge and cooperation.
