The Melamine Scare

Another crisis has hit the world. This time now comes from one of the world’s most relevant human consumable-the milk. What is scary about this is that there are already reported incidents of death among children in China.

So what is really melamine? Wikipedia defines melamine as: an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide. It is formed in the body of mammals who have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants. Melamine is generally used in plastics, adhesives, countertops, dishware, whiteboards and other industrial processes.
A lot of questions have already been raised as to why melamine was added into milk and infant powder formula. According to the World Health Organization (WHO) web site, it all started in China where adulteration has occurred; water has been added to raw milk to increase its volume. As a result of this dilution the milk has a lower protein concentration. Companies using the milk for further production (e.g. of powdered infant formula) normally check the protein level through a test measuring nitrogen content. The addition of melamine increases the nitrogen content of the milk and therefore its apparent protein content.

What are the health effects of melamine consumptions in humans? According to WHO, there are no direct human studies on the effect of melamine. However, the effect can be based on the effects of melamine to animals which have been subjected to studies. And it has found out that it has adverse health effects. Melamine alone causes bladder stones in animal tests. When combined with cyanuric acid, which may also be present in melamine powder, melamine can form crystals that can give rise to kidney stones.

These small crystals can also block the small tubes in the kidney potentially stopping the production of urine, causing kidney failure and, in some cases, death. Melamine has also been shown to have carcinogenic effects in animals in certain circumstances, but there is insufficient evidence to make a judgment on carcinogenic risk in humans.

So how do you know whether you are infected with melamine poisoning? Some symptoms and signs are irritability, blood in urine, little or no urine, signs of kidney infection, and high blood pressure.

The best thing to do now is to stop buying products from China especially milk, chocolates, drinks. And more importantly be updated on the recent developments of product testing that your government is doing.

Will Pacman survive against Golden Boy?

Manny" Pacquiao, the Filipino boxing superstar and international boxing superstar Oscar De La Hoya will face each other on December 6,2008 to show to the world who is rightful to be called world boxing superstar.

Some speculations are spreading like wild fire in the internet this time that Manny will have so much difficulty in facing the Golden Boy. The reasons are quite obvious. Manny has a four-inch height disadvantage, he is going up two weight divisions after only one fight in the lightweight category, and he has a shorter reach against De La Hoya.

But with these disadvantages, let us not also discredit Manny's advantage. He is quick, power puncher, and younger than de La Hoya. These if it will be used by Manny to the fullest, then definitely he has the chance to beat Oscar. Let us just wait and see on December 6. But one thing I am sure is that all fans of Manny are praying that he will win the fight.

Global Warming: How Warm Is Too Warm?



By: James Nash

One of the more startling stories recently was an article on the climate in Alaska, where the average temperature has risen seven degrees in the last 30 years and mosquitoes have shown up in normally frigid Barrow, the northernmost town in North America.



Large portions of Alaska are melting and other strange things are happening. Just a few hours' drive from Anchorage, a four-million-acre spruce forest has been killed by beetles, a development that is both astonishing and depressing. It is believed to be the largest loss of trees to insects ever recorded in North America.



"Government scientists," wrote the author, "tied the event to rising temperatures, which allow the beetles to reproduce at twice their normal rate."



Meanwhile, enormous wildfires have been raging in bone-dry regions of the West and Southwest. Fires whipped by high winds in the mountains of eastern Arizona have driven thousands of residents from their homes. One local official, John Stewart, said: "The forest is burning like you're pouring gasoline on it. And the wind is like taking a blow torch to it."



In Colorado, which is enduring its worst drought in decades, residents have been trying to cope with at least five major fires, including the largest in the state's history. Investigators believe it was deliberately set by a U.S. Forest Service worker. The long drought and continuing hot weather provided the conditions that enabled this apparent act of arson to explode into an unprecedented conflagration.



Big fires are becoming the rule. By late last week authorities reported that in the first six months of this year, nearly two million acres have burned or are currently burning in the United States, which is almost twice the average of the last 10 years.



Strange, indeed. Mosquitoes in northernmost Alaska. Much of the West and Southwest ablaze. Extended droughts. Extreme heat waves.



Can you say global warming?



The year 2003 was, globally, the second hottest on record. The hottest was 1998.



Now imagine that just a few more years go by and the world becomes hotter still, which will almost certainly be the case. What then?



Do you think, maybe, we should be paying more attention to this?



What is missing in most conversations in the U.S. about global warming is a sense of urgency. A Bush administration report earlier this month acknowledged that human activity - the burning of fossil fuels that send heat-trapping gases into the atmosphere - was the primary cause of the recent warming of the planet, and that the warming will result in some extremely serious consequences in the U.S.



President Bush (who has distanced himself from his own administration's report) wants to rely mostly on voluntary - not mandatory - efforts to reduce greenhouse gas emissions. Under the president's strategy, it's estimated that emissions will actually increase over the next decade. We're speeding toward a wall and the president is not only refusing to step on the brake, he's accelerating.



Ten years is too long to wait to do something real about this problem. Dr. David Armstrong, a professor of geosciences who is an expert on climate change, has studied the imminent threat that planetary warming poses to the world's coral reefs. These are ecosystems so abundant in animal and plant life that they are sometimes called the rain forests of the oceans.



Dr. Armstrong noted that one of the essential questions of the global warming debate is, "How warm is too warm?"



When you consider that the increased warming is already threatening to decimate the world's coral reefs, and that we're already seeing the melting of the tundra in Alaska, and that alpine ecosystems are already being squeezed off the tops of mountains, it's not too difficult to reach the conclusion that "too warm," in Dr. Armstrong's words, "isn't awfully far from where we already are."



Closing our eyes and pumping another decade's worth of greenhouse gases into the atmosphere at the current very dangerous rate would not seem to be a very bright idea. The gases remain in the atmosphere for centuries, and in some cases millenniums, which means the damage cannot quickly be undone.



What a miserable legacy for this generation to leave to its children and grandchildren.

How Recycling Vehicles Can Save Millions of Barrels of Oil



By: Everette Jamison

Everyone is talking about the skyrocketing price of gasoline. Americas dependence on foreign oil has been the subject of much scrutiny, and a desire to find ways to release the tethers of oil dependence. One of the most popular ways is to find alternative sources for fuel.


However, many people don't realize that a cost-effective and green way to partially release those tethers is by recycling used auto parts and automobiles. According to the Automotive Recyclers Association, recycling vehicles saves a projected 85 million barrels of oil per year, which would have been used in the manufacturing of new parts.


Not only do recycling cars and automotive parts create less of an impact on oil used per capita, recycling also makes a positive environmental impact. Imagine driving down a rural highway and looking to your left and then right. House after house, farm after farm might have cars and trucks deteriorating in the yard. Each of these vehicles leaks engine fluids scarring and polluting the earth.


While those cars piled up along that highway are posing potential environmental hazards, professional automotive recyclers must comply with a list of local and federal laws that deal with waste generated by those salvaged cars and trucks. In addition to keeping the land free of the pollutants from abandoned cars and trucks, recycling can potentially produce enough steel for car manufacturers to produce another 13 million new vehicles, according to the ARA.


Recycling those cars could also lead to potential income for not only the owners who sell their seemingly worthless cars and trucks, but also for the recyclers. When automobile recyclers process old cars, parts are salvaged before the car is reduced to scrap metal. Once these parts are refurbished, they can be made available at local parts stores and through the Internet at a substantially cheaper price sometimes up to 50 percent cheaper.


Since many automobile recyclers maintain a database of cars and/or car parts available, these recycled parts could be of great benefit for the many car enthusiasts around the world. Those enthusiasts would likely find parts much easier for their pet projects. After all what is a refurbished car but a completely recycled car?


While a junkyard or landfill could house the leftovers from all those used and abused cars, why not recycle? Recycling auto parts not only makes sense for the environment but for everyones wallet, so think twice the next time the need arises.
