Why should humans be concerned about the extinction of wild species?

Do polars bear or any other species really matter?
I think it is sad that species that we might never see in the earth again is gone. When I see a documentary on Siberian tigers disappearing due to shortage of food, I always want to help..
But also theoretically, that it might cause chain reaction, where one extinction might cause other species because they are so dependent on each other.
