I didn't say America was a "brown, dusty polluted wasteland". I fact, I was not even talking about all America, I was only talking about the USA, and the millions of peanuts they serve every day on their flight.
Of course there are peanuts growing in the USA. But there are so many flights every day that this is not enough. Believe me, more than 50% of the peanuts served in the USA were grown in South America (which is, in fact, "American soil", too!).
