Since I live near Uruguay (Buenos Aires is in the other side of the wide De la Plata river), I can contribute with some results of our research. Fart of the problem resides on defartures of airplanes carrying fartly people and fartly cattle to attend fartistic events and many farties, butt to put things afart, we must consider the fart that many people living in small afartments in Buenos Aires (literally Good Airs) contribute so much, that a strong counter-current of gas (or counterfart) has grown across the river and fartially obscured the sun for weeks and alarmed the Fire Defartments of both coasts, and that's the problem.

Thanks to all farticipants for allowing me to publish my opinion. I already feel fart of a team ! (sorry for my English) - Best regards escamillo@ciudad.com.ar :))
