Najveći pomor u historiji izazvao je goreći ugalj !

Researchers at the University of Calgary have discovered evidence suggesting that massive volcanic eruptions at the time burnt significant volumes of coal, producing choking clouds of ash and dust that had broad impact on global oceans, and may explain the massive devastation, an event known as the Permian extinction. It was the Earth's most severe extinction event, with up to 96% of all marine species^[4] and 70% of terrestrial vertebrate species becoming extinct^[5] It is the only known mass extinction of insects.^[6][7] Some 57% of all families and 83% of all genera were killed.

Rakitnica: Naravno ne mislim na današnji pomor. Prije 250 miliona godina spaljivanje velikih količina uglja izazvalo je najveći pomor ikad zabilježen na planeti Zemlji. Ako mislite da su sadašnji masovni pomori životinja slučajni, rekao bih ... gorko se varate. Razlika između gornje i donje slike zorno ilustrira razliku između zimske mikroklime Sarajeva i Bjelašnice. Odnosno drastične razlike kad ugalj gori i kad ne gori. Ukratko, brrr lakše se diše, bronhi. Od prirode se najbolje uči, ma nisi lud da sjediš kući. Idemo u planine !. Ojla ojla ojlalalala.
