“Key West has become an imitation of its former self, its eccentricities commoditized for sale to tourists. That “character” you see with a parrot on his shoulder is about as authentic as vinyl siding, employed to provide local color. Gargantuan cruise ships dock two or three times a week, disgorging passengers by the thousands to troll the cheesy T-shirt shops on the main drag, Duval Street. And with all sorts of diversions to keep visitors occupied, like parasailing and jet skiing, tourist season is year-round, clogging the streets with autos, bikes, motor scooters, and pedestrians. I”

“The total distance—11,741 miles—gave me sticker shock. Round it up to twelve thousand. Almost halfway around the world! It seemed slightly mad, but then it might do me good. To make such an epic road trip, discovering places I’d never been, rediscovering others, never knowing what I’d find beyond the next curve or hill, would be to recapture the enchantment of youth, a sense of promise and possibility. The cicada chirped incessantly in my head. I clicked back to the first map. Looking at it brought on a mixture of eagerness and reluctance. The buzzing grew more shrill. If you don’t go now, geezer, you never will. I listened to my inner cicada, and the uneasiness subsided. If I’d learned anything, it was that the things you do never cause as much regret as the things you don’t. But”

“Nitrogen fertilizer is a significant contributor to the world’s carbon footprint. Its production is energy intensive because the chemical process involved requires both heat and pressure. Depending on the efficiency of the factory, making 1 ton of fertilizer creates between 1 and 4 tons CO2e. When the fertilizer is actually applied, between 1 and 5 percent of the nitrogen it contains is released as nitrous oxide, which is around 300 times more potent than CO2. This adds between 1.7 and 8.3 tons CO2e to the total footprint,11 depending on a variety of factors.12 Here’s how the science of it goes. All plants contain nitrogen, so if you’re growing a crop, it has to be replaced into the soil somehow or it will eventually run out. Nitrogen fertilizer is one way of doing this. Manure is another. Up to a point there can be big benefits. For some crops in some situations, the amount of produce can even be proportional to the amount of nitrogen that is used. However, there is a cut-off point after which applying more does nothing at all to the yield, or even decreases it. Timing matters, too. It is inefficient to apply fertilizer before a seed has had a chance to develop into a rapidly growing plant. Currently these messages are frequently not understood by small farmers in rural China, especially, where fertilizer is as cheap as chips and the farmers believe that the more they put on the bigger and better the crop will be. Many have a visceral understanding of the needs for high yields, having experienced hunger in their own lifetime, so it is easy to understand the instinct to spread a bit more fertilizer. After all, China has 22 percent of the world’s population to feed from 9 percent of the world’s arable land. There are other countries in which the same issues apply, although typically the developed world is more careful. Meanwhile in parts of Africa there is a scarcity of nitrogen in the soil and there would be real benefits in applying a bit more fertilizer to increase the yield and get people properly fed. One-third of all nitrogen fertilizer is applied to fields in China—about 26 million tons per year. The Chinese government believes there is scope for a 30 to 60 percent reduction without any decrease in yields. In other words, emissions savings on the order of 100 million tons are possible just by cutting out stuff that does nothing whatsoever to help the yield. There are other benefits, too. It’s much better for the environment generally, and it’s cheaper and easier for the farmers. It boils down to an education exercise... and perhaps dealing with the interests of a fertilizer industry.”

“Go seasonal, avoiding hothouses and air freight. Local, seasonal produce is best of all, but shipping is fine. As a guide, if something has a short shelf life and isn’t in season where you live, it will probably have had to go in a hothouse or on a plane. In the U.K., Canada, and more northern parts of the U.S., in January, examples are lettuce, asparagus, tomatoes, strawberries, and most cut flowers. Apples, oranges, and bananas, by contrast, almost always go on boats. Adopting this tip religiously can probably deliver a 10 percent savings on a typical diet.”
