Here is a quiz to help deepen the understanding of why it is important to preserve the ozone layer.
Ozone (O3) is a triatomic molecule, consisting of three oxygen atoms. Ozone protects living organisms by preventing damage from ultraviolet light reaching the Earth's surface. O3 is the formula for ozone. It has three oxygen atoms.
The ozone layer is important as it protects the Earth against most Ultraviolet B (UVB) rays coming from the sun, which are very harmful for the body. Ultraviolet B (UVB) rays can cause various diseases as well as mutation of cells. It is always important to protect oneself against UVB, even in the absence of ozone depletion, by wearing hats, sunglasses, and sunscreen. However, these precautions will become more important as ozone depletion worsens.
The ozone layer is expected to return to normal levels by about 2050, but it is very important that the world comply with the Montreal Protocol; delays in ending production and use of ozone-depleting substances could cause additional damage to the ozone layer and prolong its recovery.
