Absorbing UV radiation

Releasing chlorine atoms that prevent ozone reformation

Increasing the concentration of ozone

Reducing the amount of UV radiation reaching the Earth's surface

Chlorine directly absorbs UV radiation, preventing it from reaching ozone.

Chlorine catalyzes the conversion of ozone ($O_3$) back into oxygen ($O_2$), without being consumed in the process.

Chlorine combines with ozone to form stable, harmless compounds.

Chlorine increases the rate at which ozone is naturally produced.

A process that cools the Earth's surface.

A natural process where heat is trapped near Earth's surface.

A phenomenon caused solely by human activities.

The depletion of the ozone layer.

Oxygen (O2)

Nitrogen (N2)

Carbon Dioxide (CO2)

Argon (Ar)

Carbon Dioxide ($CO_2$)

Methane ($CH_4$)

Nitrous Oxide ($N_2O$)

All gases have equal impact.

Ozone depletion

Ocean acidification

Decreased global temperatures

Increased biodiversity

Formation of ozone ($O_3$)

Formation of carbonic acid ($H_2CO_3$)

Release of oxygen ($O_2$)

Absorption of nitrogen ($N_2$)

Increased availability of carbonate ions ($CO_3^{2-}$)

Decreased concentration of hydrogen ions ($H^+$)

Reduced ability to absorb calcium from seawater

Lower concentration of carbonate ions ($CO_3^{2-}$)

Habitat destruction

Increased recycling efforts
