UV rays & my SKIN
Melanoma, the most serious form of
skin cancer, is now one of the most
common cancers among
adolescents and young adults ages
15-29. While melanoma accounts
for about three percent of skin
cancer cases, it causes more than
75 percent of skin cancer deaths.
UV exposure and sunburns,
particularly during childhood, are
risk factors for the disease.

UV rays & my EYES
Cataracts are a form of eye damage
in which a loss of transparency in
the lens of the eye clouds vision. If
left untreated, cataracts can lead to
blindness. Research has shown that
UV radiation increases the likelihood
of certain cataracts. Although
curable with modern eye surgery,
cataracts diminish the eyesight of
millions of Americans and cost
billions of dollars in medical care
each year. https://www.epa.gov/sunsafety/healtheffects-uvradiation#:~:text=Immune%20Suppression,s

UV rays & my IMMUNE
SYSTEM
Scientists have found that
overexposure to UV radiation may
suppress proper functioning of the
body’s immune system and the
skin’s natural defenses. For
example, the skin normally mounts a
defense against foreign invaders
such as cancers and infections. But
overexposure to UV radiation can
weaken the immune system,
reducing the skin’s ability to protect
against these invaders. https://www.epa.gov/sunsafety/healtheffects-uvradiation#:~:text=Immune%20Suppression,s

UV rays & my ENVIRONMENT
Ultraviolet radiation not only affects
humans, but wildlife as well.
Excessive UV-B inhibits the growth
processes of almost all green plants.
There is concern that ozone depletion
may lead to a loss of plant species and
reduce global food supply. Any change
in the balance of plant species can
have serious effects, since all life is
interconnected. Plants form the basis of
the food web, prevent soil erosion and
water loss, and are the primary
producers of oxygen and a primary sink
(storage site) for carbon dioxide.https://www.canada.ca/en/environmentclimate-change/services/airpollution/issues/ozone-layer/depletionimpacts/health-environmentaleffects.html#environment.
