We'll ruin ourselves in the end if we eat and eat and eat and eat and eat and eat and eat and eat. In the end, extinction for most species. Then we won't have chicken meat and steak to eat.
But that's where capitalism kicks in...it's not really in McDonald's best interests to let cows & chickens to go extinct, so they're gonna keep food species populous.
Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, in order to assure the survival and the success of liberty.
~John F. Kennedy
