Consider the nematode roundworm, the most abundant of all animals. Four out of five animals on Earth are nematode worms — if all solid materials except nematode worms were to be eliminated, you could still see the ghostly outline of most of it in nematode worms.

My father had a very simple view of life: you don’t get anything for nothing. Everything has to be earned, through work, persistence and honesty. My father also had a deep charm, the gift of winning our trust. He was the kind of man with whom many people dream of spending an evening.

PETA doesn't want stressed animals to be cruelly crowded into sheds, ankle-deep in their own crap, because they don't want any animals to die ever and basically think chickens should, in time, gain the right to vote. I don't want animals stressed or crowded or treated cruelly or inhumanely because that makes them probably less delicious.
