Recent theory says that epidemics, not hunters, killed extinct species like the giant bear, mammoth, etc. Undoubtedly the fossils abound with the traces of microbes and viruses. But one unbeatable argument contradicts this theory. Never in history has a sickness obliterated a species. The plagues that killed countless millions have always spared individuals who sooner or later developed immunity.
Insects have developed resistance to insecticides so immunity is a universal trend.
Only humans are able to inflict total extinction. A relatively recent report issued by the great manitous of finance and economy stated that Haiti's situation is worse than it was one year ago. International aid to this country is applied in such a way that it competes with local activities, repressing instead of stimulating them. They certainly were willing to swallow their words few days later. In reality it is a return to the old Metternich's and Hitler's concept that the world needs a 'leader' in order to function.
