Today’s motto for ozone conservation is: Ozone for life. And it is important that children know how crucial this element is to maintain life on Earth, only then can we stop its destruction.
It was in the late 1970s when the scientific community warned about the danger of a hole in the ozone layer. This hole in Earth’s protective shield continues to threaten the life of the planet. Cases of skin cancer, cataracts, and other diseases continue to increase. Despite the progress, and international agreements must continue in battle.
What is ozone and why is it so important?
We have to explain to children that ozone is a gas composed of three oxygen atoms that only exists under certain specific circumstances. In the stratosphere is where the ozone layer is, this is between 15 and 50 kilometers high from the surface.
Ozone and the ozone layer is very important because it makes the beings that live on Earth as a shield, barrier or protective layer, to everyone. The ozone layer protects us from the sun’s ultraviolet rays, absorbing and filtering radiation and sunlight that reaches the earth and oceans. Because of the action or activities of the human being, as a result of the use of chlorofluorocarbonated gases has caused a hole in the ozone layer, Despite the efforts, and some good news, the hole is still open.
The latest scientific assessment by the World Meteorological Organization (WMO) and the UN Environment Programme reveals that the ozone layer has recovered between 1 and 3 per cent every decade since 2000. But we have to keep working on it, it cannot be opened again.
Resources to explain the ozone layer to children
There are several materials and videos on Youtube that raise awareness about the importance of maintaining and rebuilding the ozone layer. This same line explains how recycling contributes to the non-proliferation of more polluting gases that end the ozone layer.
We recommend some videos, for example:
- Narigota, the adventure of water, an educational series in which environmental care is instilled through the adventures of a drop of water and friends, a cloud and an ice cube.
- In the EU Professor’s Corner there is a story in which a child discovers how humans generate greenhouse gases and learn what can be done to avoid it. In this same portal you will find pedagogical sheets and proposals for activities on the environment.
- In English only, Green Cooling for a Warming Wold, this video deals directly on how our appliances, for example the dishwasher, influence climate and, consequently, the ozone layer.
Material of the United Nations Environment Programme
As we have pointed out on several occasions climate change, and the ozone hole, are problems that concern all people, the United Nations through its Environment Programmehas created different materials that you can download to work with your children the need to be sustainable.
The defending character of the Earth is Ozzy Ozone, who, through two intrepid ozone molecules, Ozzy and Zoe, shows very visual content about the Sun and Earth, the Earth’s atmosphere, UVA rays and ozone holes. It also gives us some ideas for boys and girls to get down to work and learn how to take care of the environment. If your children are not that young, they can download The History of Ozone, where they will enter the chronology of the ozone layer through vignettes and with explanatory text.
It is essential to explain everything related to the ozone layer to children, so that they are aware of its importance, its current problem and what we can do among all to protect it or reverse its destruction.
