Pethegreat;3494492 The plague did not wipe us out, it simply limited the population. The flu of 1915 did the same thing. If bird flu goes the same way, it will kill a few hundred million, but at the end of the day we will still be on this rock.
The plague and the 1915 flu did not have the advantage of high speed mass air travel.
It is likely that within just a single day, from one host, a virus could spread to millions of people.
Person A, lives in a rural village. Person B is visiting rural village and shakes hands with A. The virus passes.
2 hours later, B is in a major international airport, on his way home. At this time, he has what he thinks is a 'tickly cough' from the air con. Through this cough and the air con, he is infecting thousands of people.
Person B gets on the plane, and due to the planes internal air systems, infects everyone on the plane.
Person B then infects thousands upon arrival at his destination.
Just to rub things in abit, B now goes home and infects wife and kids.
Granted, this may be a very worse case scenario, but just look at how fast a virus could potentially spread if it had a rapid enough reproduction cycle. This is why avian flu and sars were to be so deadly - air travel spreads disease at rediculous rates.
Well if we prolong our life on this planet for as long as possible, our ultimate end will be to do with the sun. Either the sun will die and we won't have sufficient technology to provide light and warmth to the population including the things that we feed on. Or, if the sun dies and we do manage to stay in the light and warm, the sun will expand and the gravitational pull will probably kill us all :) Or, less frequently a star just explodes thus the Earth will be evaporated into space and no one will ever know we existed.
the world is going to end in 2012, because this is the year in which this oldest calander to date ends the "Aztec calander". it doesnt matter how the world will end its just going to end.
