What's Fair?

What's fair?
Drawing straws to make decisions when we were young was fair.
The lottery is fair.
Tossing a coin is fair.
Life...wait...
Why is it that the biggest thing, life, isn't fair? If it was fair, my dad wouldn't have had cancer. If it was fair, my great grandpa wouldn't have died from cancer; my grandma wouldn't have been in pain as she died.
If life was fair, love would conquer everything: even death. If life was fair, love would be a Disney movie; good people would be treated the way they deserve to be treated; liars wouldn't exist; Africa wouldn't be in such poverty; the polar bears in the North Pole wouldn't be dying; people would care more for the environment; the one-ster would have listened to the Lorax; and more people would speak for the trees.
