Every year on 16th September, the International Day for the Preservation of the Ozone Layer is celebrated across the globe. On this day 32 years ago, 197 countries signed a treaty to phase out the use of substances that harm or deplete the ozone layer.
We learnt that life on earth is protected from harmful UV rays by a layer in the stratosphere called the ozone layer and that this shield is now being deteriorated due to certain man-made chemicals. We also learnt about what we could do to stop the depletion of this layer!
In September 2015, World Leaders committed to the . 17 goals to achieve 3 extraordinary things in the next 15 years. To realise these Goals, everyone, however young they are, needs to take part. So join our movement, teach young people about the Goals and encourage them to become the generation that changed the world.
The UN says that the ozone layer is 'showing signs of recovery' (BBC News, September 2014)
