Unprecedented economic growth, coupled with 1.5 billion more people, will put pressure on resources—particularly energy, food, and water—raising the specter of scarcities emerging as demand outstrips supply.

Many scientists worry that recent assessments underestimate the impact of climate change and misjudge the likely time when effects will be felt. Scientists currently have limited capability to predict the likelihood or magnitude of extreme climate shifts but believe—based on historic precedents—that it will not occur gradually or smoothly. Drastic cutbacks in allowable CO₂ emissions probably would disadvantage the rapidly emerging economies that are still low on the efficiency curve, but large-scale users in the developed world—such as the US—also would be shaken and the global economy could be plunged into a recession or worse.

Experts currently consider 21 countries, with a combined population of about 600 million, to be either cropland or freshwater scarce. Owing to continuing population growth, 36 countries, home to about 1.4 billion people, are projected to fall into this category by 2025.”

On the morning after a black man won the White House, America’s tears of catharsis gave way to unadulterated joy. Our nation was still in the same ditch it had been the day before, but the atmosphere was giddy. We felt good not only because we had breached a racial barrier as old as the Republic. Dawn also brought the realization that we were at last emerging from an abusive relationship with our country’s 21st-century leaders. The festive scenes of liberation that Dick Cheney had once imagined for Iraq were finally taking place—in cities all over America.

The debates unnerved both candidates. When he was preparing for them during the Democratic primaries, Obama was recorded saying, “I don't consider this to be a good format for me, which makes me more cautious. I often find myself trapped by the questions and thinking to myself, ‘You know, this is a stupid question, but let me … answer it.’ So when Brian Williams is asking me about what's a personal thing that you've done [that's green], and I say, you know, ‘Well, I planted a bunch of trees.’ And he says, ‘I’m talking about personal.’ What I'm thinking in my head is, ‘Well, the truth is, Brian, we can’t solve global warming because I f---ing changed light bulbs in my house. It’s because of something collective’.”

“Well, I haven’t heard from them personally, but one of the campaigns’ transition team did ask me through an intermediary if—you know the article is 8,000 words—could I prepare a one or two page summary for them. And my response to that was ‘Don’t you have staffers who do that?’ The reason I wrote 8,000 words is because that’s what I needed to tell the story. If I could have done it in one or two pages I would have.”

“I was just reading an article in The New York Times by Michael Pollen about food and the fact that our entire agricultural system is built on cheap oil. As a consequence, our agriculture sector actually is contributing more greenhouse gases than our transportation sector. And in the mean time, it's creating monocultures that are vulnerable to national security threats, are now vulnerable to sky-high food prices or crashes in food prices, huge swings in commodity prices, and are partly responsible for the explosion in our healthcare costs because they're contributing to type 2 diabetes, stroke and heart disease, obesity, all the things that are driving our huge explosion in healthcare costs. That's just one sector of the economy. You think about the same thing is true on transportation. The same thing is true on how we construct our buildings. The same is true across the board.”

“In a conference call arranged by the McCain campaign [responding to the interview], Sen. Charles Grassley, R-Iowa, called it ‘ludicrous to blame farmers for obesity and pollution.’ Said Grassley: “It shows that Sen. Obama doesn't have a very good foundation in American agriculture. And people in agriculture need to know that if Sen. Obama is going to get his ideas on agriculture from a professor at Cal-Berkeley, they should think twice about what they are voting for.”

Let's allow these harsh new realities to force us to do something that Alice Waters has been advocating for decades: Let's finally embrace the truth that food is not something to be taken for granted. As a culture, we need to be more curious about where our food comes from. We need to buy from farmers who are trying to do things the right way. We need to think before we eat.

…American suburbia requires an infinite supply of cheap energy in order to function and we have now entered a permanent global energy crisis that will change the whole equation of daily life. Having poured a half-century of our national wealth into a living arrangement with no future — and linked our very identity with it — we have provoked a powerful psychology of previous investment that will make it difficult for us to let go, change our behavior, and make other arrangements.

In 40 years I could see living in the world’s largest city, a megalopolis, extending from New York City to Philadelphia and engulfing all of New Jersey. New Jersey could change the state motto to “The Overdevelopment State.” As we already have more cars per square mile than any other state, we could change the shape of the license plates from a rectangle to the outline of a car.

Rising gas prices and various other considerations have prompted this increased round of speculation on whether the suburbanization of America will reverse, but the right answer needs to take into account the fact that what policy choices we make will have a strong impact on the course of the future.

In 1970, the average American ate about 16.4 pounds of food a week, or 2.3 pounds daily. By 2006, the average intake grew by an additional 1.8 pounds a week. Among other things, that's an extra half pound of fat weekly - mostly from oils and shortening. That doesn't count the fat in the extra quarter pound of meat Americans now eat every seven days.

“Genetically and physiologically, it should be impossible” for all U.S. adults to become overweight, said Dr. Lan Liang of the federal government’s Agency for Healthcare Research and Quality, one of the researchers on the study. However, she told Reuters Health, the data suggest that if the trends of the past 30 years persist, “that is the direction we're going.”

…morbidly obese blobs who spend their monotonous days zooming heavily around on hovering easy chairs, watching private TV screens, and drinking meals-in-a-cup. They can’t walk, and have even forgotten how to interact physically with one another, raising the question of how they’ve been procreating for the past few centuries. Machines take charge of their every need to the point (possibly) of no return.

…subjects were asked to rate a variety of sausages. People who scored high on “social authority” - they believed it was important to support people in power - tended to label the “vegetarian” sausage as inferior, even when the vegetarian sausage was actually from a cow. Likewise, people who scored low on “social power values” tended to score the vegan sausage much higher than the beef sausage, even when they were actually eating meat. Instead of judging the food product on its merits, they ended up preferring the product that more closely conformed to their value system.

I counted four types of passengers. There are thrifty ones looking to save a few bucks on plane tickets. There are those who are scared of flying, a group that has no doubt grown in recent years. There are the zealots—without exception, older men—who describe themselves with charming lack of inhibition as “rail junkies,” “railroad nuts,” “train buffs,” or, my personal favorite, “railfans.” The rest—indeed the majority—say they’re here for “the experience.”

A report to be released Monday by the Transportation Department shows that over the past seven months, Americans have reduced their driving by more than 40 billion miles. Because of high gasoline prices, they drove 3.7% fewer miles in May than they did a year earlier, the report says, more than double the 1.8% drop-off seen in April.

…says that [ANWR] production could range from 510,000 barrels to 1.45 million barrels per day. If Congress approved development in 2008, it would take 10 years for oil production to commence, EIA said. With production starting, then, in 2018, EIA said the most likely scenario is that oil would peak at 780,000 barrels per day in 2027 and decline to 710,000 barrels per day in 2030. Currently, the United States consumes about 20 million barrels of oil per day.

…furthers many U.S. policy goals, such as reducing oil consumption and curbing emissions. But, coupled with a rapid shift away from gas-guzzling vehicles, it also means consumers are paying less in federal fuel taxes, which go largely to help finance highway and mass-transit systems. As a result, many such projects may have to be pared down or eliminated.

…supports development of high-speed rail networks across the country. Providing passengers with safe high-speed rail will have significant environmental and metropolitan planning advantages and help diversify our nation’s transportation infrastructure. Our domestic rail freight capacity must also be strengthened because our demand for rail transportation has never been greater, leaving many key transportation hubs stretched to capacity. Obama is committed to renewing the federal government’s commitment to high speed rail so that our nation’s transportation infrastructure continues to support, and not hinder, our nation’s long-term economic growth.

The American leader, who has been condemned throughout his presidency for failing to tackle climate change, ended a private meeting with the words: "Goodbye from the world’s biggest polluter." He then punched the air while grinning widely, as the rest of those present including Gordon Brown and Nicolas Sarkozy looked on in shock.

This week’s crop included lettuce, broccoli, zucchini, basil, kale, cucumbers, dill, cilantro, fennel, parsley, rainbow chard, garlic scapes and radicchio. Keeping in mind that, for a 25 week growing season, this averages to about $24 a week. While some supermarkets might have produce that looks as good, I think it would be very challenging to get as much food for the relatively modest cost.

While in Miami over the weekend, I received an e-mail from home base with the subject line: Scapes Are Here!
Even at a distance of 900-plus miles from home, I was delighted by the news that one of my long-anticipated produce items had made its annual debut at the farmer's market. The "scape" in question is hardly a typo or a secret code word; it's shorthand for garlic scape, a part of the garlic plant that is a garlic lover's nirvana.

…popping some into the freezer to top off my winter soups. I use this pesto on brushetta, pasta, eggs, foccacia, and just about anything I grill like shrimp, salmon, chicken. It’s also fabulous added to mayonnaise and smeared on a big roast beef sandwich.

Since my cookbook indexes came up empty in a search for scapes, I called my dad for advice. “Garlic scapes?” he said. “Do you mean green garlic?”
He was referring to the tender crop of garlic that also appears in the market in spring, bulbs still attached to their green floppy tops. Having become addicted to their juiciness and musky sweetness, I always make a point to buy plenty when I see them.

Replacing red meat and dairy with chicken, fish, or eggs for one day per week reduces emissions equal to 760 miles per year of driving. And switching to vegetables one day per week cuts the equivalent of driving 1160 miles per year.

We made some ice cream at home last weekend. Someone had given one of the kids an ice cream maker a while ago and we finally got around to using it. We decided to make orange sherbet. It took a pretty long time and it didn’t taste very good but the worst part was how expensive it was. We spent about $12 on heavy cream, half-and-half, orange juice, and food coloring — the only ingredient we already had was sugar — to make a quart of ice cream. For the same price, we could have bought at least a gallon (four times the amount) of much better orange sherbet. In the end, we wound up throwing away about three-quarters of what we made. Which means we spent $12, not counting labor or electricity or capital costs (somebody bought the machine, even if we didn’t) for roughly three scoops of lousy ice cream.

There’s a lot to be said for the nutritional value of home-grown food. But again, since one person can grow only so much variety, there are bound to be big nutritional gaps in her diet that will need to be filled in.

One in three children born in the United States five years ago are expected to become diabetic in their lifetimes, according to a projection by the Centers for Disease Control and Prevention. The forecast is even bleaker for Latinos: one in every two.

This is a pretty strong argument against the perceived environmental and economic benefits of locavore behavior…

The latest data show cereal prices rising by more than 8% a year. Both flour and rice are up more than 13%. Milk, cheese, bananas and even peanut butter: They're all up by more than 10%. Eggs have rocketed up 30% in a year. Ground beef prices are up 4.8% and chicken by 5.4%.

“It takes around 400 pounds of corn to make 25 gallons of ethanol. It’s not going to be a very good diet but that’s roughly enough to keep an adult person alive for a year.”

“Crop-based biofuels are not part of the solution. They, in fact, add to the problem. Whether Al Gore has caught up with that, somebody ought to ask him,” the professor said. “There are lots of solutions, real solutions to climate change. We need to get to those.”

Rye flour stocks have been depleted in the United States, and by June or July there will be no more U.S. rye flour to purchase, said Lee Sanders, senior vice president for government relations and public affairs at the American Bakers Association.

For bakers, rye grain is not the only supply stock that is declining. In the past the market has typically had a three-month surplus of wheat stocks to serve as a cushion against supply interruptions, but now the surplus is down to less than 27 days worth of wheat, Sanders said.

A recent study conducted by the Center for Agricultural and Rural Development at Iowa State University (which receives funding from grocery manufacturers and livestock producers) reported that U.S. ethanol production could consume more than half of U.S. corn, wheat and coarse grains by 2012, driving up food prices and causing shortages. The study estimates that booming ethanol production has already raised U.S. food prices by $47 per person annually.
