Q: why is that that nowadays, there are lots of new bacterias and viruses emerging (in broader sense, almost anywhere in the world killing not only humans but also other forms of life such as birds, plants, amphibians and so on)?
what i'm think is that one reason of it is because of the Global Warming. Earth became hotter and hotter that a new species of bacterium or virus emerges out of the past generation of this microscopic pathogens. It mutates in short... it mutates because of the hot environmen (it triggers the bacterias and viruses to "adjust" to its new environment so that it will survive and thus creating a new species of microorganism... another reason maybe that this nasty microorganism is immune to this strong drugs that used to be very effective against them... I don't know what will happened to us if all of this pathogenic microorganism became "invincible"... scary huh?
