I went down to the sewers in London and looked at a campaigning group in London called RATS, Rowers Against Thames Sewage, and I went to Sewage School and hung out with kids learning to make sewage soup and how to clean sewage. And it was great - really good fun.
Sending a container from Shanghai to Le Havre emits fewer greenhouse gases than the truck that takes the container on to Lyon.
We know about man's impact on the ocean in terms of fishing and overfishing, but we don't really know much about what's happening underneath the water. And in fact, shipping has a role to play here, because shipping noise has contributed to damaging the acoustic habitats of ocean creatures.
Because sanitation has so many effects across all aspects of development - it affects education, it affects health, it affects maternal mortality and infant mortality, it affects labor - it's all these things, so it becomes a political football. Nobody has full responsibility.
Perhaps we believe that everything travels by air, or magically and instantaneously like information (which is actually anchored by cables on the seabed), not by hefty ships that travel more slowly than senior citizens drive.
The days of languorous shore leave are long gone. Overnight stays are unheard of and sailor towns a distant memory. In better ports, seafarers head for a seamen's mission.
China's use of 'night soil,' as the Chinese rightly call a manure that is collected after dark, is probably the reason that its soils are still healthy after four millennia of intensive agriculture, while other great civilizations - the Maya, for one - floundered when their soils turned to dust.
I feel special. Most women will have only one menopause, and they will hate it. I will have two, and when the second one comes, I will know what is coming. I am having my extra menopause as a cure. I have endometriosis.
We are using the same water that the dinosaurs drank, and this same water has to make ice creams in Pasadena and the morning frost in Paris.
In some of the great cities of Europe - Paris, Vienna, Prague, and Brussels - tourists bored with life above ground can descend below. All these cities have sewer museums and tours, and all expose their underbelly willingly to the curious. But not London, arguably the home of the most splendid sewer network in Europe.
'MaerskKendal' is a rarity with its British flag, the 'LONDON' home port painted on its bow, its two British chief officers, and its portrait of the queen in the mess room, apparently common courtesy on British ships, but a little alarming to me.
Seafarers are used to being exploited. At sea, the captain moans at chandlers who supply ships with green bananas that will never ripen; at fruit that goes moldy obscenely fast; at sub-standard meat.
Research into endometriosis is as scanty as funding.
Sewage works that serve big cities run into trouble when the cities grow up around them.
Before containers, transport costs ate up 25 percent of the value of whatever was being shipped.
The more ships have grown in size and consequence, the more their place in our imagination has shrunk.
I find Suez astonishing for the first hour. It is a ditch in a desert, but a stunning one. The sensation of being hemmed in by huge ships, moving at a stately pace through a man-made waterway, is extraordinary.
Half of the hospital beds in sub-Saharan Africa are filled with people suffering from what are generally known as water-related diseases.
Along with all the other stunning statistics China can provide, it can also claim to be the world leader in making energy from human excrement. Biogas, as this energy is known, can be produced from the fermentation of any organic material, from wood to vegetables to human excreta.
