Effects on Plants

UV light excess causes plants

to have trouble with their photosynthesis process,

causing less crop

production in overall.

THE OZONE LAYER

IS THINNING

Effects on Animals

High levels of UV light kills

phytoplankton (basic food source),

disrupting oceanic food chains.

It also causes an increase of

CO2 in the atmosphere.

Global decline in amphibians

(toads and salamanders).

  • Increase incidence of skin cancer
  • Premature aging of the skin
  • Increase incidence of cataracts
