Hot Air Balloon!
A man in a hot air balloon, realizing he was lost, reduced altitude and spotted a woman below. He descended further and shouted to the lady, ‘Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don’t know where I am.’
The woman below replied, ‘You’re in a hot air balloon, hovering approximately 30 feet above the ground. You’re between 40 and 41 degrees north latitude and between 59 and 60 degrees west longitude.’
‘You must be in IT,’ said the balloonist.
‘Actually I am,’ replied the woman, ‘How did you know?’
‘Well,’ answered the balloonist, ‘everything you have told me is technically correct but I’ve no idea what to make of your information and the fact is I’m still lost. Frankly, you’ve not been much help at all. If anything, you’ve delayed my trip ‘.
The woman below responded, ‘You must be in Management.’
‘I am,’ replied the balloonist, ‘but how did you know?’
‘Well,’ said the woman, ‘you don’t know where you are or where you’re going. You have risen to where you are due to a large quantity of hot air. You made a promise, which you’ve no idea how to keep, and you expect people beneath you to solve your problems. The fact is you are in exactly the same position you were in before we met, but now, somehow, it’s my bloody fault‘.
Is humanity at fault for Earthquake Deaths?
“Every year, around 60,000 people die worldwide in natural disasters. The majority of the deaths are caused by building collapse in earthquakes, and the great majority occurs in the developing world. This is despite the fact that engineering solutions exist that can almost completely eliminate the risk of such deaths.” (Reference)
Earthquake Cost Benefit Analysis For California = $100 Million a year (Profit not Loss)
Humanity needs to invest in better buildings to save earthquake lives but doesn’t see the cost benefit. However according to Dr. Iain Stewart of BBC’s “How Earth Made Us: Deep Earth” fame – California’s cash-flow, for example, is enhanced by around $100 million – every year – because of the region’s San Andreas Fault’s positive influence on California’s geology.(Reference)
Deadly and Yet Necessary, Quakes Renew the Planet
Scientists argue that in the very long view, the global process behind great earthquakes is quite advantageous for life on earth – especially human life.
Powerful jolts ……are inevitable side effects of the constant recycling of planetary crust, which produces a lush, habitable planet. Some experts refer to the regular blows – hundreds a day – as the planet’s heartbeat.
The advantages began billions of years ago, when this crustal recycling made the oceans and atmosphere and formed the continents. Today:
- it builds mountains,
- enriches soils,
- regulates the planet’s temperature,
- concentrates gold and other rare metals and
- maintains the sea’s chemical balance.
Plate tectonics (after the Greek word “tekton,” or builder) describes the geology. The tragic downside is that waves of quakes and volcanic eruptions along plate boundaries can devastate human populations.
“It’s hard to find something uplifting about 150,000 lives being lost,” said Dr. Donald J. DePaolo, a geochemist at the University of California, Berkeley. “But the type of geological process that caused the earthquake and the tsunami is an essential characteristic of the earth. As far as we know, it doesn’t occur on any other planetary body and has something very directly to do with the fact that the earth is a habitable planet.”
Many biologists believe that the process may have even given birth to life itself.
The main benefits of plate tectonics accumulate slowly and globally over the ages. In contrast, its local upheavals can produce regional catastrophes, as the recent Indian Ocean quake made clear.
Even so, scientists say, the Dec. 26 tsunamis may prove to be an ecological boon over the decades for coastal areas hardest hit by the giant waves.
Dr. Jelle Zeilinga de Boer, a geologist at Wesleyan University who grew up in Indonesia and has studied the archipelago, says historical evidence from earlier tsunamis suggests that the huge waves can distribute rich sediments from river systems across coastal plains, making the soil richer.
“It brings fertile soils into the lowlands,” he said. “In time, a more fertile jungle will develop.”
Dr. de Boer, author of recent books on earthquakes and volcanoes in human history, added that great suffering from tectonic violence was usually followed by great benefits as well. “Nature is reborn with these kinds of terrible events,” he said. “There are a lot of positive aspects even when we don’t see them.”
Plate tectonics holds that the earth’s surface is made up of a dozen or so big crustal slabs that float on a sea of melted rock. Over ages, this churning sea moves the plates as well as their superimposed continents and ocean basins, tearing them apart and rearranging them like pieces of a puzzle.
The process starts as volcanic gashes spew hot rock that spreads out across the seabed. Eventually, hundreds or thousands of miles away, the cooling slab collides with other plates and sinks beneath them, plunging back into the hot earth.
The colliding plates grind past one another about as fast as fingernails grow and over time produce mountains and swarms of earthquakes as frictional stresses build and release. Meanwhile, parts of the descending plate melt and rise to form volcanoes on land.
… despite such staggering losses of life, said Robert S. Detrick Jr., a geophysicist at the Woods Hole Oceanographic Institution, “there’s no question that plate tectonics rejuvenates the planet.”
Moreover, geologists say, it demonstrates the earth’s uniqueness. In the decades after the discovery of plate tectonics, space probes among the 70 or so planets and moons that make up the solar system found that the process existed only on earth – as revealed by its unique mountain ranges.
In the book “Rare Earth” …., Dr. Peter D. Ward and Dr. Donald Brownlee of the University of Washington argued …. that the slow recycling of planetary crust was uncommon in the universe yet essential for the evolution of complex life.
“It maintains not just habitability but high habitability,” said Dr. Ward, a paleontologist. (Dr. Brownlee is an astronomer.) Most geologists believe that the process yielded the earth’s primordial ocean and atmosphere, as volcanoes spewed vast amounts of water vapor, nitrogen, carbon dioxide and other gases. Plants eventually added oxygen. Meanwhile, many biologists say, the earth’s first organisms probably arose in the deep sea, along the volcanic gashes.
“On balance, it’s possible that life on earth would not have originated without plate tectonics, or the atmosphere, or the oceans,” said Dr. Frank Press, the lead author of “Understanding Earth” (Freeman, 2004) and a past president of the National Academy of Sciences.
The volcanoes of the recycling process make rich soil ideal for producing coffee, sugar, rubber, coconuts, palm oil, tobacco, pepper, tea and cocoa. Water streaming through gashes in the seabed concentrates copper, silver, gold and other metals into rich deposits that are often mined after plate tectonics nudges them onto dry land.
Experts say the world ocean passes through the rocky pores of the tectonic system once every million years or so, increasing nutrients in the biosphere and regulating a host of elements and compounds, including boron and calcium.
Dr. William H. Schlesinger, dean of the Nicholas School of the Environment and Earth Sciences at Duke, says one vital cycle keeps adequate amounts of carbon dioxide in the atmosphere. …..an appreciable level is needed to keep the planet warm enough to support life.
“Having plate tectonics complete the cycle is absolutely essential to maintaining stable climate conditions on earth,” Dr. Schlesinger said. “Otherwise, all the carbon dioxide would disappear and the planet would turn into a frozen ball.”
Dr. Press, who was President Jimmy Carter’s science adviser, said the challenge in the coming decades would be to keep enjoying the benefits of plate tectonics while improving our ability to curb its deadly byproducts.
“We’re making progress,” Dr. Press said. “We can predict volcanic explosions and erect warning systems for tsunamis. We’re beginning to limit the downside effects.”
I think its fair to say we are all sad for the lost of our loved ones but Earthquakes Benefit Humanity both in the future just as they have done for us all in the past.
