The ozone layer above the Earth is a vital protective shield. Its most important function for us is to filter out Ultra Violet (UV) rays from sunlight, which harm humans, animals, plants and micro-organisms. On the other hand, ground-level ozone is dangerous for our health. Find out what causes ozone depletion and what the sources of ground-level ozone are; find out the effects of ozone depletion and ground-level ozone; find out some of the solutions put forward by the European Union.

Ozone depletion and sources of low-level ozone
The vital ozone layer above the Earth is getting thinner, yet dangerously high concentrations of ozone are found lower down in the atmosphere.
Ground-level ozone is a pollutant that damages our health; high-level ozone forms a vital shield above us that protects us from harmful UV light. Effects of ozone problems
We must stop using the gases that harm the ozone layer and reduce emissions of pollutants that cause ground-level ozone.
