Large Hole Develops in Ozone Above Canadain Arctic

An unusually large Ozone hole has developed over the Canadian Arctic.

Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.

Under a hole in the Ozone layer, harmful rays enter our planet.

UV radiation is well-known to cause skin cancer in humans if one is frequently exposed.
