>Additionally, and even more devastating,there was a poisonous mist of fluorine and sulfur dioxide which
settled over the entire country, burning up grazing lands and
killing livestock, and lasted far longer. It is believed that up to 80
percent of livestock died, and an estimated one-fifth of the
human population of Iceland (approximately 10,000 people)
perished from the combined effects of the mists and the ensuing
famine caused by their loss.
Sorry to get all depressing but it is disturbing
