    The damage to the ozone layer is a cause for concern because if the ozone layer
    in the atmosphere disappears completely, then all the extremely harmful ultraviolet
    radiations coming from the sun would reach the earth. These ultraviolet radiations
    would cause skin cancer and other ailments in men and animals and also damage the
    plants. In an attempt to protect the ozone layer, the United Nations Environment
    Programme (UNEP) unanimously forged an agreement among its member countries to
    freeze CFC production at 1986 levels.
