There is at least one very scary scenario circulating in email that might lead a reader to believe the planet is doomed because of the oil disaster in the Gulf. A little perspective calms any fears.
I received an email today that made these claims (edited for brevity):
An engineer of considerable experience says watch this carefully:
"Heard your mention of the oil disaster in the Gulf of Mexico this morning, and you are totally missing the boat on how big and bad of a disaster this is.
"Now they're saying 200,000 gallons a day. That'sover a million gallons of crude oil a week!
"I'm engineer with 25 years of experience. I've worked on some big projects with big machines. Maybe that's why this mess is so clear to me.
"First, the BP platform was drilling for what they call deep oil. They go out where the ocean is about 5,000 feet deep and drill another 30,000 feet into the crust of the earth. This it right on the edge of what human technology can do. Well, this time they hit a pocket of oil at such high pressure that it burst all of their safety valves all the way up to the drilling rig and then caused the rig to explode and sink. Take a moment to grasp the import of that. The pressure behind this oil is so high that it destroyed the maximum effort of human science to contain it.
"When the rig sank it flipped over and landed on top of the drill hole some 5,000 feet under the ocean.
"Now they've got a hole in the ocean floor, 5,000 feet down with a wrecked oil drilling rig sitting on top of is spewing 200,000 barrels of oil a day into the ocean. Take a moment and consider that, will you!
"If we can't cap that hole that oil is going to destroy the oceans of the world. It only takes one quart of motor oil to make 250,000 gallons of ocean water toxic to wildlife. Are you starting to get the magnitude of this?
"We're so used to our politicians creating false crises to forward their criminal agendas that we aren't recognizing that we're staring straight intopossibly the greatest disaster mankind will ever see. Imagine what happens if that oil keeps flowing until it destroys all life in the oceans of this planet. Who knows how big of a reservoir of oil is down there.
"Not to mention that the oceans are critical to maintaining the proper oxygen level in the atmosphere for human life."
Well, let's put this 200,000 gallons of oil per day into perspective.
First, oil floats on water (it is less dense than water).
Second, just how much oil does this represent with respect to the size of oceans?
Consider this analysis:
Oceans are very big. All oceans combined have a surface area of about 130,000,000 square miles. So, how long would it take to cover the surface of all the oceans with oil from this disaster in the Gulf?
Well, to answer that, we must first decide on how thick a coating of oil we want to consider. Let's assume that oil is very bad to float on the ocean (never mind that whales and other sea creatures have a very high amount of oil in their bodies). Suppose it is so bad that we don't want to tolerate a depth of even one micron (one-millionth of a meter). Just how long would it take at 200,000 gallons per day to create a one micron thick layer of oil over all the planet's oceans?
One gallon is 0.134 cubic feet. So 200,000 gallons per day amounts to 26,800 cubic feet per day. Converting that to inches, 200,000 gallons of oil per day is 46,310,400 cubic inches of oil per day. That is the same as having a one inch deep layer of oil covering 46,310,400 square inches of ocean.
There are 25,400 microns in an inch. So a one micron depth would cover 25,400 times as much area as a one inch depth. Therefore, a one micron depth of oil would cover 1,176,284,160,000 square inches every day that 200,000 gallons of oil gushes into the Gulf. Sounds like a lot, doesn't it?
Let's put it in perspective.
Just one square mile of ocean surface has 4,014,489,600 square inches of surface. So in one day, if the oil were spread over a one micron depth it would cover 293 square miles.
Still sound like a lot?
Total surface area of all oceans combined is about 130,000,000 square miles. That means at 200,000 gallons per day, it would take 443,686 days to spread a coating of oil just one micron thick over the surface of all the oceans.
Accounting for leap years, it would take 1,215 years to cover the oceans of our planet with just one-millionth of a meter depth of oil being produced at 200,000 gallons per day!
So, you see, things aren't always as they might appear at first glance.
Is the oil a problem? Locally, yes. But it will never begin to approach a planetary scale problem.
Of bigger concern is how many people will be frightened by the kind of email quackery that claimed our planet was in peril from this spill?
As with most things in life, perspective is everything.
Bob Webster, a descendant of Daniel Webster's father and early American patriot, Ebenezer Webster, has always had a strong interest in early American history, our Constitution, U.S. politics, and law. Politically he is a constitutional republican with objectivist and libertarian roots. He has faith in the ultimate triumph of truth and reason over deception and emotion. He is a strong believer in our Constitution as written and views the abandonment of constitutional restraint by the regressive Progressive movement as a great danger to our Republic. His favorite novel is Atlas Shrugged by Ayn Rand and believes it should be required reading for every high school student so they can understand the dangers of tolerating the growth of unconstitutional crushingly powerful central government. He strongly believes, as our Constitution enshrines, that the interests of the individual should be held superior to the interests of the state.
A lifelong interest in meteorology and climatology spurred his strong interest in science. Bob earned his degree in Mathematics at Virginia Tech, graduating in 1964.
