Robdar - We all fear the inevitable....death. We empathise with others and fear the unknown.
I think it is Gandalf in Lord of the Rings, who says that death is just another path we must take. But it seems to me, that it is 'life' that we should fear more than death.
The suffering of others, be it animal or human is painful to see but the reason and answer must be out there somewhere.
I feel there is nothing to fear in death and that we will always be with out loved ones.....but how that is so, we have to wait and see.
That there is nothing to fear in death is, I think, the great secret that those who rule us do not want us to know, hence all the nonsensical religious mysticism that is used to control us.
Perhaps our polar bears suffered and died but they moved on to their next great adventure.
The polar bears fate makes us aware of that ultimate reality that we are powerless in certain circumstances and we cannot stop bad things from happening.
That awful reality, powerlessness is frightening.
We see the poweful polar bear brought to nothing and we empathise with its suffering.
But remember, THEY want you to believe that you / we caused it by driving our car / switching on an extra lightbulb etc.
