| Visualization:
You have just arrived home from work and turn on the television. It
is the year 2010 and the ozone layer is at its lowest level in recorded
history. Despite the summer heat, you have had to wear a jacket with long
sleeves and a collar for the walk home. You remove your wide brimmed hat,
UV protected sunglasses and the SPF-30 sunscreen it is now necessary to
apply when you go outside. Your outside gear hangs besides your family's.
Your two-year-old daughter toddles toward you for a hug. She has yet to
play in the sun and must be kept covered for trips between buildings.
The news on the television is not good "Melanoma has reached a new high
for Canadians. One in 5 people is now diagnosed with this type of cancer
during their lives. The continuing increase is linked to ultraviolet B
radiation that used to be absorbed by the ozone layer.
In a related story, UV radiation is being blamed for the declining fish
stocks, along with continued over fishing. Phytoplankton is dying at tremendous
rates in the world's oceans due to higher UV levels. Fish feed on the phytoplankton.
"The decrease in the ozone layer has caused the Canadian government
to encourage residents above the Arctic Circle to settle farther south
due to increased incidents of cataracts and damage to immune systems."
You prepare your dinner and marvel at the increase in the price of meat
and other protein supplements such as soybeans. Because of the increase
in the cancer and cataracts in free range cattle, meat producing animals
are housed in crowded, expensive, indoor barns. The soybean yield has decreased
by 25 percent due to the plants sensitivity to increased ultraviolet radiation.
Rover scratches at the door, wanting to go for a run. Looking at the
sky, you think better of it. Having the cancerous growth removed from his
eye was expensive. The dog will have to wait until after dark before going
out.
As night falls, you can see the moon light shimmering across the pond
down the hill behind the house. But what you hear is silence. The voices
of the frogs are gone. They, too, have been silenced by UV radiation caused
by the thinning of the ozone layer.
