"Documentary film of scenes of wild carnivores preying on other animals is usually edited so to not show the harsh reality of nature. A TV program I watched by chance 12 years ago reported the fact without concealing the details ... Five hyenas surrounded an animal like a deer at night and bit its abdomen. The animal had already lost the vigor to run away or to resist and was immobilized by terror at the persistent attack of the hyenas. In a moment, the skin of its abdomen was torn up and the bloody flesh was exposed throughout the abdomen. The animal's four legs staggered but it didn't fall; the legs stood and supported the body full of injuries. The hyenas bit the animal's exposed bloody flesh, bit by bit, and began to eat it. The animal didn't fall down yet and stood still with all its might, but no one saved this pitiful animal; it was eaten alive ...This occurrence is not special but repeated everywhere on the earth every day. I was deeply shocked, however, as if I had learned nature's true colors of cruelty for the first time. I had the intuition that such thing should absolutely not exist. Even if people permit it as natural law, I must deny it firmly. I wanted to drive away the hyenas to save the animals from being eaten alive ... If I had not seen the TV program by chance, I would have continued to eat meat and to hold a superficial philosophy ignorant of the cruelty of nature."
