"I bought from some villagers a young osprey they had caught on a sandbank, in order to rescue it from their cruel hands. But then I had to decide whether I should let it starve, or kill a number of small fishes every day in order to keep it alive. I decided on the latter course, but every day the responsibility to sacrifice one life for another caused me pain."
