Fireballs, Meteors, Meteorites, Asteroids and Comets have increased over the past 3 years.
Around 15,000 tons of meteoroids, micrometeoroids and different forms of space dust enter Earth's atmosphere each year.
The meteor that rocked the world in February 2013 also left a trail of dust around it. NASA's Suomi NPP Satellite tracked the plume and showed that it had traveled around the northern hemisphere and back to Chelyabinsk, Russia in 4 days.

Could Earth be threatened by extraterrestrial bacteria and chemicals from Comet ISON's coma debris, or from meteorites in general?
Reports of microfossil or microbial life discoveries in meteorites have a long and tangled history stretching over half a century.
The Polonnaruwa Meteorite
Minutes after a large fireball was seen by a large number of people in the skies over Sri Lanka on 29 December 2012, a large meteorite disintegrated and fell in the village of Araganwila, which is located a few miles away from the historic ancient city of Polonnaruwa.
At the time of entry into the Earth’s atmosphere on 29 December 2012, the parent body of the Polonnaruwa meteorite would have had most of its interior porous volume filled with water, volatile organics and possibly viable living cells. A remarkable coincidence that should be noted is that within several days of the meteorite fall, various parts of Sri Lanka experienced episodes of red rain, yellow rain, green rain as well as black rain (period December 2012/January 2013).
There is tentative evidence for the presence of organisms, including diatoms, in meteorites falling over the same time period. These microorganisms are likely to have served as nuclei for the condensation of rain drops.

The identification of fossilised diatoms in the Polonnaruwa meteorite is firmly established and unimpeachable. Since this meteorite is considered to be an extinct cometary fragment, the idea of microbial life carried within comets and the theory of cometary panspermia is thus vindicated.
Comets and Meteorites can contain living bacteria from space along with other chemicals including arsenic. But with around 15,000 tons of space dust enter Earth's atmosphere each year including the larger cometary fragments made it to the ground, you would think space dust is no threat to the Earth and humanity.
But ‘what if’ space dust or cometary fragments contains life threatened organisms or chemicals?
Soon the earth will be doubled dusted with unknown biological and chemical debris from comet C2012 S1- ISON.
The space dust from ISON could be in our atmosphere for years. In the event the debris contains fossils as in the meteorite dust Sri Lanka, it will be interesting to see what effect, if any, it will have on the biology of earth or.. we may expect a pandemic? Like the Black Death of 1347 (1347-1350) one of the most deadly pandemics in human history. The Black Death of 1347 was probably caused by a corrupted atmosphere.
