How 16 ships create as much pollution as all the cars in the world

As ships get bigger, the pollution is getting worse. The most staggering statistic of all is that just 16 of the world’s largest ships can produce as much lung-clogging sulphur pollution as all the world’s cars.
Because of their colossal engines, each as heavy as a small ship, these super-vessels use as much fuel as small power stations.
But, unlike power stations or cars, they can burn the cheapest, filthiest, high-sulphur fuel: the thick residues left behind in refineries after the lighter liquids have been taken. The stuff nobody on land is allowed to use.

There are now an estimated 100,000 ships on the seas, and the fleet is growing fast as goods are ferried in vast quantities from Asian industrial powerhouses to consumers in Europe and North America.

Each is a quarter of a mile long and can carry up to 14,000 full-size containers on their regular routes from China to Europe.

Emma – dubbed SS Santa by the media – brought Christmas presents to Europe in October and is now en route from Algeciras in Spain to Yantian in southern China, carrying containers full of our waste paper, plastic and electronics for recycling.

Bunker fuel is also thick with sulphur. International Maritime Organisation (IMO, the UN body that polices the world’s shipping) rules allow ships to burn fuel containing up to 4.5 per cent sulphur. That is 4,500 times more than is allowed in car fuel in the European Union. The sulphur comes out of ship funnels as tiny particles, and it is these that get deep into lungs.
Thanks to the IMO’s rules, the largest ships can each emit as much as 5,000 tons of sulphur in a year – the same as 50million typical cars, each emitting an average of 100 grams of sulphur a year.
With an estimated 800million cars driving around the planet, that means 16 super-ships can emit as much sulphur as the world fleet of cars.

The 'Abiotic Oil' Controversy

http://www.rense.com/general58/biot.htm
www.rense.com - Abiotic Oil
The debate over oil's origin has been going on since the 19th century. From the start, there were those who contended that oil is primordial - that it dates back to Earth's origin - or that it is made through an inorganic process, while others argued that it was produced from the decay of living organisms (primarily oceanic plankton) that proliferated millions of years ago during relatively brief periods of global warming and were buried under ocean sediment in fortuitous circumstances.
During the latter half of the 20th century, with advances in geophysics and geochemistry, the vast majority of scientists lined up on the side of the biotic theory. A small group of mostly Russian scientists - but including a tiny handful Western scientists, among them the late Cornell University physicist Thomas Gold - have held out for an abiotic (also called abiogenic or inorganic) theory. While some of the Russians appear to regard Gold as a plagiarist of their ideas, the latter's book The Deep Hot Biosphere (1998) stirred considerable controversy among the public on the questions of where oil comes from and how much of it there is. Gold argued that hydrocarbons existed at the time of the solar system's formation, and are known to be abundant on other planets (Jupiter, Saturn, Uranus, and some of their moons) where no life is presumed to have flourished in the past.
The abiotic theory holds that there must therefore be nearly limitless pools of liquid primordial hydrocarbons at great depths on Earth, pools that slowly replenish the reservoirs that conventional oil drillers tap.
Meanwhile, however, the oil companies have used the biotic theory as the practical basis for their successful exploration efforts over the past few decades. If there are in fact vast untapped deep pools of hydrocarbons refilling the reservoirs that oil producers drill into, it appears to make little difference to actual production, as tens of thousands of oil and gas fields around the world are observed to deplete, and refilling (which is indeed very rarely observed) is not occurring at a commercially significant scale or rate except in one minor and controversial instance discussed below.
The abiotic theorists also hold that conventional drillers, constrained by an incorrect theory, ignore many sites where deep, primordial pools of oil accumulate; if only they would drill in the right places, they would discover much more oil than they are finding now. However, the tests of this claim are so far inconclusive: the best-documented "abiotic" test well was a commercial failure.
Thus even if the abiotic theory does eventually prove to be partially or wholly scientifically valid (and that is a rather big "if"), it might have little or no practical consequence in terms of oil depletion and the imminent global oil production peak.
[Or the moral dilemma once it finally dawns on us that the black, thick fluid is -actually- Earth's blood! Because, whether it's abiotic or biotic, these 'reductionist-materialists' just want to know how much longer they can keep on raping Gaia.]
