Coalition viewpoint...The writer misses a few very important points in this blog, revealing at least a lack of understanding of military operations and at most, a disregard for the safety of our armed forces, even here at home.

The Navy promotes farming operations around Lemoore Naval Air Station for several important reasons.  They require large amounts of open space around a base that focuses on training flight crews. Birds attracted to non-farmed land pose a danger to those flight operations.  Crop growing activities also help the Navy mitigate air quality issues in the region.  Those are important issues for the pilots and for the residents of the surrounding communities.

The writer also demonstrates how sloppy his research and understanding is when he repeatedly refers to the Air Force when, in fact, the facility is a Navy base.  And his assertion that the Air Force can get non-bird crops if they want because, "the air force can kill anyone who disagrees..." is simply ridiculous and irresponsible............

What, exactly, is "corporate agriculture"?  
Is it a large, faceless entity with little regard for people or the environment?  
Not likely.  Click HERE or listen to the radio to meet one of California's "corporate" farmers and learn how family farms make up the backbone of California agriculture.

 

 

Farming in California is as diverse as the people who live here.  Throughout the state, farmers work long hours to bring us the food and fiber we enjoy.  Join us and learn more about farming and the history of agriculture in California. grnrightro.gif

Why Does Bottled Water Have an Expiration Date?

Our very own Jason English is wondering why his Poland Spring has a “drink by” date on it when common sense dictates that water doesn’t go bad. To him I say, “It’s your own damn fault.”

Well, not personally his fault, but the fault of his home state of New Jersey.

A 1987 NJ state law required all food products sold there to display an expiration date of two years or less from the date of manufacture. Labeling, separating and shipping batches of expiration-dated water to the Garden State seemed a little inefficient to bottled water producers, so most of them simply started giving every bottle a two-year expiration date, no matter where it was going.
Now, the U.S. Food and Drug Administration has never established or suggested a limitation on the shelf life of bottled water as long as it’s produced in accordance with regulations and the bottle remains properly sealed. Makes sense, because it’s, you know…water. Even Dirty Jerz caught on to this fact and amended the law a few years ago. But the expiration date has been an industry norm for so long that many producers have just kept it on there.

Better WIth Age? While “expired” unopened bottled water isn’t going to do you any harm, it isn’t going to get better with age, either. The plastic that water is packaged in — usually polyethylene terephthalate (PET) for retail bottles and high-density polyethylene (HDPE) for water cooler jugs –- is slightly porous, so the water can pick up smells and tastes from the outside world. Keep a case of bottled water in the basement for a year or so and it’s going to pick up some interesting flavors. There’s nothing better on a hot summer day than a 2007 Evian, with hints of dust and a crisp kitty litter finish!

Major cache of fossils unearthed in L.A.

A nearly intact mammoth, dubbed Zed, is among the remarkable discoveries near the La Brea Tar Pits. It's the largest known deposit of Pleistocene ice age fossils.

The largest known deposit of fossils from the last ice age has been found in what might seem to be the unlikeliest of places -- under an old May Co. parking lot in L.A.'s tony Miracle Mile shopping district.

Researchers from the George C. Page Museum at the La Brea Tar Pits have barely begun extracting the fossils from the sandy, tarry matrix of soil, but they expect the find to double the size of the museum's collection from the period, already the largest in the world.

Among their finds, to be formally announced Wednesday, is the nearly intact skeleton of a Columbian mammoth -- named Zed by researchers -- a prize discovery because only bits and pieces of mammoths have previously been found in the tar pits.

But researchers are perhaps even more excited about finding smaller fossils of tree trunks, turtles, snails, clams, millipedes, fish, gophers and even mats of oak leaves. The first excavators at La Brea threw out similar items in their haste to find prized animal bones, and crucial information about the period was lost.

"This gives us the opportunity to get a detailed picture of what life was like 10,000 to 40,000 years ago" in the Los Angeles Basin, said John Harris, chief curator at the Page. The find will make the museum "the major library of life in the Pleistocene ice age," he said.

Because of its need for haste, the team also is pioneering a new technique for extracting the fossils. Most paleontologists spend days to weeks carefully sifting through the soil at the site of a dig. In this case, however, huge chunks of soil from the site have been removed intact and now sit in large wooden crates on the back lot of the Page.

The 23 crates range in size from 5 feet by 5 feet by 5 feet to 19 feet by 12 feet by 10 feet -- from the size of a desk to that of a small delivery truck -- and are responsible for the excavation's informal name, Project 23.

The site of the old two-story parking garage, formerly used by the now-defunct May Co., is located immediately west and adjacent to the Page in Hancock Park. The Page's sister museum, the Los Angeles County Museum of Art, owned the building and had razed it to construct an underground parking garage that would restore parkland above the structure.

The entire Rancho La Brea area at Hancock Park is a paleontological treasure chest. Petroleum from the once-massive underground oil fields oozed to the surface over the millenniums, forming bogs that trapped and killed unsuspecting animals and then preserved their skeletons. It is now a protected site, although dispensation was granted to build the new garage.

Bottled Water Carries Hidden Cost to Earth

Good for You, Bad for Mother Earth? | $1.79 might seem like a small price to pay for a bottle of water. But it costs the Earth far more than that.

Compared to a liter of tap water, producing a liter of bottled water requires as much as 2,000 times more energy, according to the first analysis of its kind. The study also found that our nation's bottled water habit sucked up the equivalent of 32 to 54 million barrels of oil last year.

"The bottom line is that we should understand better the implications of our choices," said Peter Gleick, president of the Pacific Institute for Studies in Development, Environment, and Security in Oakland, Calif. "It suggests more ways to reduce energy use than maybe we otherwise think of."

Bottled water is a big business that is rapidly getting bigger. From 1976 to 2007, the average amount of bottled water drunk per person per year in the United States jumped from about 6 liters (1.6 gallons) to 116 liters (30.6 gallons).

In 2007, the last year for which numbers are available, Americans purchased more than 33 billion liters of bottled water. Globally, the number was 200 billion liters.

Even just since 2001, bottled water sales have increased by 70 percent in the U.S. We now buy more bottled water than either milk or beer.

But as consumption has gone up, so too have worries about what our drinking habits might be doing to the environment.

"It's a big deal," Gleick said. "And yet, no one had looked at all of the energy that goes into it. We didn't know."

To find out, he and a colleague considered three case studies: water that was bottled and used in Los Angeles; water bottled in the South Pacific and sent by cargo ship to L.A.; and water bottled in France and shipped in various ways to L.A. For each scenario, the researchers looked at all the energy involved in collecting, treating, bottling, labeling, packaging, cooling, and transporting the liquid.

For water that is consumed near its source, producing PET plastic bottles is the most energy-intensive step, according to their results, which appeared in the journal Environmental Research Letters. For bottles that make longer trips, transportation has the biggest impact.

In other words, buying water that was bottled near your home rather than in places like Fiji can help reduce your carbon footprint. Better yet, Gleick said, put away your wallet and turn on the faucet instead.

"We have very good tap water in this country," he said. "It's cheap. It's readily available. And it's much lower in energy use."

The research also shows how simple choices can have a significant impact on the environment.

"One of the conclusions we can all draw from this study is that novel materials and low-carbon energy can help," said Daniel Kammen, co-director of the Berkeley Institute of the Environment at the University of California, Berkeley. "But our own behavior is critical to cutting down not just physical waste, but also carbon waste."

Water 'more important than oil'

Dwindling water supplies are a greater risk to businesses than oil running out, a report for investors has warned.

Among the industries most at risk are high-tech companies, especially those using huge quantities of water to manufacture silicon chips; electricity suppliers who use vast amounts of water for cooling; and agriculture, which uses 70% of global freshwater, , says the study, commissioned by the powerful CERES group, whose members have $7tn under management. Other high-risk sectors are beverages, clothing, biotechnology and pharmaceuticals, forest products, and metals and mining, it says.

"Water is one of our most critical resources – even more important than oil," says the report, published today . "The impact of water scarcity and declining water on businesses will be far-reaching. We've already seen decreases in companies' water allotments, more stringent regulations [and] higher costs for water."

Droughts "attributable in significant part to climate change" are already causing "acute water shortages" around the world, and pressure on supplies will increase with further global warming and a growing world population, says the report written by the US-based Pacific Institute.

"It is increasingly clear that the era of cheap and easy access to water is ending, posing a potentially greater threat to businesses than the loss of any other natural resource, including fossil fuel resources," it adds. "This is because there are various alternatives for oil, but for many industrial processes, and for human survival itself, there is no substitute for water."

In a joint statement, CERES' president Mindy Lubber and Peter Gleick, president of the Pacific Institute, urged more companies and investors to work out their dependence on water and future supplies, and make plans to cope with increased shortages and prices.

"Few companies and investors are thinking strategically about the profound business risks that will exist in a world where climate change is likely to exacerbate already diminishing water supplies," they say.

"Companies that treat pressing water risks as a strategic challenge will be far better positioned in future," they add.

The CERES report adds to growing concern about a looming water crisis. In the Economist's report, The World in 2009 , Peter Brabeck-Letmathe, chairman of food giant Nestl├ę, wrote: "under present conditions… we will run out of water long before we run out of fuel". And at its annual meeting this year the World Economic Forum issued what it itself called a "stark warning" that "the world simply cannot manage water in the future in the same way as in the past or the economic web will collapse".

CERES, which has members in the US and Europe, made recommendations, including that companies should measure their water footprints from suppliers through to product use, and integrate water into strategic planning, and that investors should independently assess companies' water risk and "demand" better disclosure from boards.
