Hung upside down by shackles, thousands of chickens are killed every hour at the slaughterhouse.

Heard of factory farming?
"Factory farming is an attitude which regards animals and the natural world merely as commodities to be exploited for profit.
In animal agriculture, this attitude has lead to institutionalized animal cruelty, massive environmental destruction and resource depletion, and animal and human health risks."

I suppose there's little we can do to help. Not many of us can be a successful vegetarian. But we should be aware of what happens before the food is served on the plate. We may be the superior species in terms of evolution and intelligence. But being superior does not give us the right to rob other species of their right to a decent life before they die for our meals. Factory farming is far too extreme.
