A Tale of Two Tragedies
Concern about the safety of nuclear energy is now on everyone's mind. Is nuclear energy worth it? If we abandon it, won't our dependence on fossil fuel increase even more? We have not figured out a way to dispose of the deadly radioactive waste materials and spent fuel rods from nuclear reactors. The United States currently has 70,000 tons of it, and nowhere to put it!
Nuclear energy will never be 100% safe. If you believe exponents of nuclear energy claiming so, I have a bridge I would like to sell to you. Germany has already decided to phase away its reactorss but it is unlikely that other countries will, or can, follow suit. There is too much at stake here, political and economic. Nuclear energy is economically not competitive. A nuclear plant can cost $5 billion or more and the price of producing nuclear energy is about 30 percent higher than that of coal or gas.
Japan will learn from its experience and recover but unless we curb our voracious appetite for energy, we have to be prepared to suffer the consequences of a nuclear disaster next time a tsunami invades a coastal city.
While Japan copes with its monumental tragedy, another one is unfolding in Libya. The tyrant Gadhafi has been holding Libyans hostage for decades. When the people finally rose in revolt, he began slaughtering them with his tanks, artillery, planes and foreign mercenaries. Now that the United States, France and Britain have begun bombarding Gadhafi's forces - and not a moment too soon - the rebels have regained their hope and are counter-attacking. They will ultimately prevail but Libya is likely to go through a long period of civil unrest and bitter in-fighting. Many more Libyans will die but that seems to be the price people pay when a cruel and sociopathic dictator like Gadhafi, who made the world unsafe for democracy, falls.

Concern Over Nuclear Radiation Leak in Japan
The Devastation in Japan caused by the earthquake and the tsunami defies imagination. To the loss of lives, displacement of people and damages to property and infrastructure, the possibility of radiation leak from an explosion in the Fukushima Daiichi Nuclear Power Station (about 150 miles north of Tokyo) has added a sinister dimension. If exposed to lethal ionizing radiation, and the Japanese have a visceral reaction to it from Hiroshima and Nagasaki, the effect of this natural disaster can take decades to heal.
Of course, it is only human nature to consider the darkest possibilities in the wake of something as catastrophic as this. Japanese engineers and experts are crippling the affected nuclear reactors by flooding them with seawater to minimize any radiation leak.
Dr. C. S. Karim, a nuclear physicist, explains the radiation leak: “
“The Emergency Core Cooling System is provided to take care of cooling during this period. As a backup to electricity, which may not have been available after the tsunami, there are other procedures such as immediate injection of borated water from an accumulator. The problem arises when there is damage to the reactor cooling system. Pipes in the system may be broken due to strong vibrations from an earthquake. Then, even if there is coolant available and pumps are operating, the water may not reach the reactor core to remove the residual heat.
“Any reactor design uses a concept called ‘defense in depth,’ that is, providing multiple barriers between the source of radiation and the environment. Most of the radiation is contained in the nuclear fuel element, comprising Uranium Oxide pellets shrouded in Zircaloy cladding.
“The reactor cooling system has two loops. Heat that is carried by water from the reactor core is transferred indirectly to another cooling loop. Steam, thus produced, flows through the turbine to produce electricity. If, as the reports are suggesting, there were explosions inside the reactor, they could have been due to the loss of coolant.”
We do not yet know the exact level of radiation leak in northeastern

Nature's Fury Overpowers Japan
The 8.9 earthquake and the resulting tsunami has left thousands dead in Japan's coastal regions. Signs of devastation - dead bodies, stunned survivors, fire, submerged cars like toys - are coming at us from all directions.
Our complacency is shaken to the core. Everyday we hear of innovations and discoveries, the monuments to man's ingenuity, and we bask in the wonder of it all. Then a primal force overturns what we call normal. We feel the terror and sense how helpless we are.
Natural calamities are occurring with more frequency and fury these days. Global warming has unleashed extremes. Fire and ice mingle to create horror and suffering, leaving us edgy. Is it coming our way, we ask? Already the Pacific tsunami has reached coastal California. The Crescent City harbor in Northern California has been wrecked, boats battered and freeways flooded.
Everything is connected, we learn in ecology 101. They certainly are. The flutter of a butterfly's wing can spawn a gale. The ferocious energy of wind on water can travel thousands of miles to snatch a family picnicking on a sun-splashed shore.
Sometimes we lose sight of our limitations. Sometimes hubris clouds our vision and we suffer from dangerous delusions. There is a balance that underlies the cosmos. When it is disturbed, through arrogance or negligence or plain foolishness, there is a terrible price to pay. The value of humility - perhaps that is what nature has been trying to teach us all along.

Haiti's Sorrow
Born in
These random thoughts passed through my mind as images of death and destruction from
Preliminary reports indicate that more than 100,000 Haitians may have perished. The infrastructure, hardy any to begin with, has been completely destroyed. Rescuing people trapped beneath the rubble seems impossible at the moment.
Fate has dealt
Whatever we can do to bring relief to the living, we must. When tragedy strikes in any corner of the world, we become aware of our common humanity. For Americans, the Katrina debacle remains a vivid reminder that such lapses cannot repeat. Already the Obama administration has dispatched several hospital ship and planeloads of emergency supplies to the devastated nation.
In the next few days and nights, Haitian will try to come to grips with what has befallen them. But perhaps they can find some solace in that people from around the globe have opened their hearts and pocketbooks for them, to help them bury their dead with dignity and bring a semblance of normalcy to their lives again.
But after the world moves on to grapple with the next crisis, Haitians themselves must bear the responsibility for reconstructing their country. The history of Haiti is tragic. The French were brutal slave owners and grew wealthy beyond their dreams from sugarcane plantations. Americans occupied the country for almost two decades. Haitian dictators killed their own countrymen by the thousands. Against this backdrop, rebuilding Haiti becomes even more challenging. But unless Haitians step up to the task, they will always be dependent on the generosity of others and that can never be a long-term solution.
Thoreau said: "If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life." Same should be true for nations. In the long run, local leadership that promotes self-reliance will be the only catalyst for fundamental national changes. In the disaster that has hit Haiti, there is obviously the need for as much aid as possible. But a few months from now, Haitians will have to think long and hard about their own responsibility and accountability.

Earthquake in South Asia
The devastating 7.6 earthquake that hit Pakistan, Kashmir, India and Afghanistan on Saturday, October 8, has already claimed over 38,000 lives. The death toll will undoubtedly rise once more bodies are retrieved. Particularly in the mountainous, rugged part of Kashmir where winter has made an early and sinister appearance, the misery of the wounded, the homeless and the destitute are beyond words. The “paradise on earth” has turned into a graveyard.
As in other regions of the United States, local mosques and charities in the Bay Area began to mobilize immediately. South Bay Islamic Association (SBIA) of San Jose and Muslim Community Association (MCA) of Santa Clara led drives to collect donations of cash, warm clothes, blankets and other necessary materials. The collections are being sent to Pakistan mostly through Edhi Foundation (www.paks.net/edhi-foundation), and Hidaya Foundation (http://www.hidaya.org/). All donations that SBIA collected on Friday, October 14, at the Jumah prayers at its 3 locations – Downtown, Evergreen and Napredak – were set aside for the earthquake victims.
The tragedy has shaken believers in this holy month of Ramadan. If there is one lesson we should take from it, it is that we must be grateful to God for what we have and not waste our life by chasing after what we don’t. When we read about barely-alive children rescued from under the rubbles whose arms or legs had to be amputated because gangrene had set in, the simple fact that we can breathe and are able to walk should be reasons enough for thanking the Creator. When we read about families huddling under trees day after day against freezing rain and howling winds, we should be thankful for the house we live in and not be consumed by thoughts of bigger, fancier houses because others have it or because we just want it. This lesson must not fade after the heart-rending images of quake victims disappear from the front pages; otherwise, we have learned nothing.
