Valentine’s Day celebrates love in all its many wonderful forms and cultural traditions. But the greatest love of record, according to DNA, might be Genghis Khan. DNA tracing reveals over 16 million people now living are related to the legendary Mogul emperor whose dynasty helped to renovate, repair, and advance China’s Grand Canal.

When Ghengis’ nephew, Kublai Khan, became emperor, he directed grain be moved northward to the new capital the dynasty had established: Dadu. Khan commanded that 816,000 tons of grain be delivered to the capital: 537,000 had to come from the fertile south. But how? The Grand Canal, China’s internal waterway.

However, there was a slight problem. When grain arrived at the Yangtze region by boat, it had to be transferred over land about 20 miles (32 kilometers) because the waterway did not stretch all the way to Dadu – yet. Local farmers were forced to loan their draft animals to the project: agriculture suffered, as did the beasts.

When Kublai Khan observed the problem, the new emperor ordered the Grand Canal add a seventh section to reach the capital. In the building project, the entire waterway was straightened and strengthened. Once the liquid highway was complete, communications improved, agriculture thrived, and the capital rose in importance. Some say the Grand Canal transformed a region into a nation. Today, Dadu continues to have a national role: it is now named Beijing.

Khan dynasty also had a national, and apparently a global role. Genghis Khan fathered five daughters and four sons with his primary wife Börte, and many more with 500 secondary spouses. Genghis Khan, master of conquest in more ways than one, may be said to have caused increases in areas of society, technology, and indeed civilization.

Oxford University’s Professor Chris Taylor-Smith analyzed DNA of males across 16 ethic populations. Many shared a notable Y chromosome. It appears that its unique characteristics can be traced to Genghis Khan. Today, if you are a male reading this post, you may be part of 0.5% of the world’s population descending from Genghis Khan who was born in 1162, died in 1227, and was – apparently – very busy in between.

Baltimore’s Francis Scott Key Bridge disaster is a tragedy. You can help here and here.Image: ‘Cable stayed suspension bridge” by Wikideas1, 2024. Pubic Domain CC0 1.0. Included with appreciation to the artist and support for Baltimore’s families who have suffered loss.
The tragedy of the Francis Scott Key Bridge brings deep sorrow for those lost and injured, as the search for those still missing continued after the accident. The Baltimore bridge was slammed by cargo vessel Dali after the 984 foot (299 meters) ship lost power and could not avoid collision. A MayDay call was sent, but it was too late. Citizens in the area rushed to help, forming a human blockade to prevent oncoming traffic from entering the bridge access.

While using waterways for transport is an ancient idea, and has recently been championed by European transport experts as more environmentally beneficial, the size of cargo ships must be considered. Europe has 23,000 miles (37,014 kilometers) of waterways: using canals and rivers for cargo transport could reduce emissions from trucks. Presently, 6.5 million trucks deliver goods across Europe, while rail carries just 5% and rivers 2%. European port operator Haropa proposed rivers and canals as a means of cargo delivery. But when European canals, as well the American Erie Canal were built, and the bridges that span these waterways, cargo vessels carrying goods were smaller.

Now, the size of the average cargo ship is considerably larger. Ships that have problems can cause major trouble, like the container ship Ever Given that got stuck in the Suez Canal. In the first three months of 2024, cargo ships have hit bridges in Argentina, China, and the United States. Some would question if waterways, and bridges, are ready for the size of cargo vessels now used. The Port of Baltimore is the 11th largest in the United States. It is an important transport center, but what are the limits of the ships that traverse its waters? What safety measures need to be in place in the world’s ports? Coastal cities around the world are some of the most important ports. Baltimore is one; Boston is another. Will sea level rise threaten the safety of ports?

While the Francis Scott Key bridge was not structurally deficient (although there has been comment on its structural redundancy, a term for extra support that can compensate for damage preventing collapse, as well as pier protection) and was certified as completely up-to-code, too many of our spans are in need of strengthening. Bridges last about 50 years before showing problems. The age of the average bridge in the United States is 42. A study by the American Road and Transport Builders Association (ARTBA) revealed that 36% of U.S. bridges – 222,000 – are in need of repair. The total cost? $319 billion. How much is currently allocated? $3.2 billion.

Bridges were once, and remain, so important to city planning and security that in ancient Rome, only the Pope and a small cadre of bishops had the right to authorize a bridge. From that historic beginning, we get our word “pontiff” (Latin “pontifex” from “pons” (bridge) + “facere” (to do or make). Only the Pontiff of Rome could issue a bridge permit. In olden days of China, there was a bridge over which only the Emperor could walk.

Many transport historians might mark stages of civilization by connections formed via bridges. London Bridge changed the commerce of the city. Its span was the location of what may be one of the first shopping malls: retail stalls built along the structure paid rent that helped support bridge repairs. London Bridge is significant, too, for what was perhaps the first worker’s compensation plan, according to King John’s document of authorization to the Lord Mayor of London.

Bridges can raise the spirit: the Brooklyn Bridge has inspired more poetry than any other bridge in history. Hart Crane’s “To Brooklyn Bridge,“offers reflections upon the span. The bridge is also connected to philosophy: it began in the mind of John Roebling who contemplated teachings of his professor at the Royal Polytechnic in Berlin: the philosopher Hegel. It was one of Hegel’s theories that gave Roebling the idea: it came to him in a flash during a hike in Bamberg. He sat down on a rock and sketched what would become the Brooklyn Bridge.

British spans were recently studied: 17 were found to be in danger of collapse and 37 were on the watch list. The Hammersmith Bridge across the Thames River showed cracks in the 100+ year-old structure, causing the banning of vehicles since 2019.

European Union bridges tend to be on the older side: many were built as part of the Marshall Plan, just after World War II in the mid 1940s. Germany’s Leverkusen Bridge developed concrete cracks and was closed to heavy vehicles in 2012. In 2018, Italy’s Morandi Bridge connecting Genoa to France collapsed in a drenching rain storm. Built with only one pair of cable stays to support each section, vulnerability may have been inherent in the design.
Will bridges, many built in earlier times for different conditions, withstand the stronger storms of climate change? Britain’s Tay Rail Bridge washed out and collapsed in a strong storm in 1879. Image: Tay Bridge Catastrophe, 1879. Image origin: public domain, author unknown.
Climate change and attendant extreme weather, including intense winds and storms creating waves and floods, may affect bridges. In areas with drought subject to wildfire, bridges might need protection in parts of the span that may contain fiberoptic cable. Concrete may seem strong, but it cracks at 500 degrees Fahrenheit and melts at 2,500 degrees. Innovations like “First Line Fire Blankets” can be applied to bridges, power cables, and even gas pipelines. Make of E-glass fiber that resists thermal conductivity, “fire blankets” can be retrofitted to protect critical infrastructure.
China’s Belt and Road Initiative (BRI) is building many new bridges. Are there opportunities for innovation that can respond to climate change? The Mohammed VI Bridge, Morocco, was a BRI project.

Older bridges may be supported by vigilance and retrofitting. Newer construction has opportunities for innovation. China’s Belt and Road Initiative, connecting Asia all the way to Africa and Europe, may tally $8 trillion. Financed in part by loans to countries that agree to the building of bridges, ports, roads, railways, China’s debts-owed increased 20% since 2013 when the project launched. More than 68 countries have signed on to participate in the project that will involve 65% of the world’s entire population. Bridges in the plan include the China-Maldives Friendship Bridge, Maputo Bay Bridges in Mozambique, Mohammed VI Bridge in Morocco, and the Peljesac Bridge in Croatia. Decisions made about bridge design, strength, maintenance, and technology may determine the future of the much of the world’s connectivity over water, and also over terrain needing aerial bypass. What are some ways bridges can be improved?

Khan commanded that 816,000 tons of grain annually, with the major share – 537,000 tones – coming from the south, be delivered to the new capital. But when the supply arrived from the Yangtze region by the canal, it still had to be transported 20 miles (32 kilometers) further to reach Dadu. To accomplish this task, draft animals were conscripted, leaving farmers without adequate help: agriculture suffered. Kublai Khan saw the problem and ordered the Grand Canal’s seventh section to be completed, straightening and improving the entire route during construction of the final leg. Once the water highway was complete, communications between and among all parts of the empire could reach the capital, as well as the grain. Some say the Grand Canal transformed a region into a nation. Today, we know Dadu as Beijing.

Kublai Khan’s uncle Genghis fathered five daughters and four sons with his primary wife Börte, and as many as 500 secondary spouses. Known as a master of conquest, Genghis Khan, 13h century warrior and ruler, left his mark on civilization, and with his DNA apparently well distributed, he may have personally caused a substantial increase in civilization. In 2003, evolutionary geneticist Professor Chris Tyler-Smith of Oxford University analyzed the DNA of males across 16 Asian ethnic populations. Many shared the same Y-chromosome array. Dating the pattern back, Tyler-Smith found the origin appears to be Genghis Khan who ruled at the time the particular DNA array first emerged and then proliferated. Today, if you are a male reading this post, you may be part of 0.5% of the world’s population descending from Genghis Khan, who was born in 1162, died in 1227, and very busy in between.

Dynasties are continuations – traditions and genetics. Kublai Khan, Genghis’ nephew, inspired the mysterious poem by Samuel Taylor Coleridge. It begins:
In Xanadu did Kubla Khan
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea…
But oh! that deep romantic chasm which slanted
Down the green hill athwart a cedarn cover!
A savage place! as holy and enchanted
As e’er beneath a waning moon was haunted
By woman wailing for her demon-lover!

Ever Given container ship stuck in the Suez Canal. What is the future of shipping? Image: wikimedia.
One ship 1,300 feet long (400 meters); 14 tug boats; 30,000 cubic meters of mud and sand cleared; 369 ships waiting in line behind the behemoth vessel: these are the elements that marked the reopening of the Suez Canal this week. When the Ever Given stopped traffic on 23 March, the Suez Canal Authority (SCA) estimated a $14 million revenue loss for each day of the blockage. Moreover, trade along the waterway that contributes 2% to Egypt’s GDP also stopped – costing $6.7 million per minute. (Russon 2021) Alianz insurer reported the Suez Canal March 2021 blockage cost between $6 billion and $10 billion.

Almost everything we touch has reached us, at some stage in the supply chain, via ship. Suez averages 106 container vessels and cruise ships per day. Trends in the container shipping industry reveal continuous pressure for size increase: since 1968, container ship capacity has increased 1,200%. (World Shipping Council, 2021) Why the pressure for bigger? One reason is because shipping is twice as energy efficient as rail and seven times more than vehicle. Shipping emits 3.1% of global CO2, but that percentage could rise as other industries decarbonize. The Energy Efficiency Design Index (EEDI) is a globally-binding design standard established by the International Maritime Organisation (IMO) to reduce climate damage caused by shipping: ships built from 2020-2024 will be required to improve energy efficiency by 15-20%, and by 30% after 2025. Many of those ships will transit the Suez Canal.

As container ships get bigger, canals will too. In 2015, Suez built a parallel waterway deepened by dredging one million cubic meters of sludge daily. Six companies did the work: Great Lakes Dredge and Dock Company (USA), Jan de Nul Group and Deme Group (Belgium), National Marine Dredging (UAE), Royal Boskalis Westminster and Van Oord (Netherlands). The Panama Canal, begun by Ferdinand de Lesseps but completed by the US, recently installed new locks on the Atlantic and Pacific sides that are 70 feet wider and 18 feet deeper than the originals. American ports like Baltimore, Charleston, Miami, Philadelphia, and Virginia have seen increased container traffic from the Panama expansion, according to the Supply Chain Management Program at MIT. The current US proposal “American Jobs Plan” allocates $42 billion for ports (air and sea) that may spur improvements.

Egypt’s famous waterway opened in 1869; 1.5 million people worked on the canal’s construction, evidence that infrastructure building creates jobs. Ferdinand de Lesseps, retired diplomat, visited his childhood friend now the khedive and viceroy of Egypt, in 1854 and gained concession to build the canal. Diplomacy remained a central value: the Suez contract Article VI states “tariffs of dues for passage…shall be always equal for all nations.” (Building the World, p. 193) To mark the inaugural opening of the Suez Canal, Giuseppe Verdi composed the opera Aida. Should the “American Jobs Plan,” aimed at rebuilding infrastructure, include funding for art?

Feeling sick? It may the drugs you just took when you drank a sip of coffee or a glass of water. Affecting not just humans but aquatic life, medications are entering the water as fast as plastic – they’re just harder to see.
Antibiotics have been found in 65% of over 70 world waterways tested. For example, a site in Bangladesh showed Metronidazole present at levels 300 times the safe limits (20,000 to 32,000 nanogram per liter (ng/l) guidelines set by AMR Industry Alliance). The most frequent contaminant? trimethoprim found at 301 of 711 river testing sites. Most prevalent antibiotic found at dangerous levels: Ciprofloxacin, in 51 of the 72 countries tested.
Chao Phraya River Drainage Basin. Image: wikimedia.
Rivers all over the world show similar results: Chao Phraya, Danube, Seine, Thames. Some areas of the world suffer infected water more: Bangladesh, Ghana, Kenya, Nigeria, and Pakistan ranked highest of sites monitored. In general, Asia and Africa frequently exceeded safety limits for antibiotics but problems were also found in Europe, North and South America. In other words, it’s global.
Of course, antibiotics save lives. But that’s just the problem: growing global resistance to antibiotics, anti fungals, antivirals caused 700,000 deaths yearly due to drug-resistant diseases, among them tuberculosis. The United Nations’ Interagency Coordination Group on Antimicrobial Resistance predicts that by 2030, over one million people will die every year due drug-resistant diseases.
PROBLEMS: Individuals are in no small part responsible: a study in California revealed half of all medications are discarded, often into the water supply. Another problem: even if we don’t intend to, individuals deposit drugs into the water supply. People take a lot of drugs, both prescription and over-the-counter; our bodies metabolize only a percentage of the intake, excreting the rest into wastewater systems. And then there are the larger systemic depositors: hospitals try to return unused drugs to manufacturers obtaining a credit or at least assured safe disposal, but care and nursing facilities may not have such arrangements. Certainly drug manufacturers generate highly concentrated waste; downstream of a New York State pharmaceutical manufacturing plant, antibiotic concentrations showed levels 1,000 times higher than normal. And then there’s agriculture: poultry and livestock farming are responsible for two trillion pounds of animal waste filled with the hormones and antibiotics fed to the animals to optimize growth and marketability.
Antibiotics harm fish and aquatic life. Image: Giant Group, Georgia Aquarium, Wikimedia.
Other ways animals are affected? Aquatic life itself is changing: so much estrogen has entered rivers and ponds that male fish are showing genetic changes including the development of intersex fish, especially downstream of wastewater treatment plants: notable is Washington’s Potomac River.
Filters are one approach: water treatment plants have been successful at filtering out ibuprofen but couldn’t catch diclofenax, another pain reliever. Chlorine used in drinking water treatment does reduce bacteria and also degrades acetaminophen and the antibiotic sulfathiazole, and also carbamazepine (by 75%). Still, chemicals are getting into our bodies simply by turning on the tap: Southern Nevada Water Authority found antibiotics, antipsychotics, beta blockers, and tranquilizers in the drinking water as far back as 2010. It is only getting worse.
SOLUTIONS
Pharmaceutical systems include manufacturing, distribution, consumption, disposal, and waste treatment: each step of the process offers opportunities for intervention and innovation. Regulations, at a national, local, or global level, can be effective: compliance is now an industry with consultants like Stericycle with programs “designed to meet regulatory requirements.” Of course, pharmaceutical businesses have in-house programs and systems, including segregating hazardous waste pharmaceuticals that are then sent to a Treatment, Storage, and Disposal Facility (TSDF). It’s a big business: UBS and Vanguard are investors, along with 500 other financial funds. Stericycle has 22,000 employees: competitors include Republic Services with 36,000 and Waste Management with 42,000 employees. It’s a business of the future: pharmaceutical use shows no sign of decreasing, although there is a movement to encourage safer drugs.

Nations and cities can take action. Water facilities such as the Jardine Water Purification Plant in Chicago, Illinois, world’s largest by volume, draws water from the American Great Lakes for distribution to 390 million urban residents. Research and innovation here could lead the way. In Europe, Germany invested one billion euro in the last two decades to water infrastructure including wastewater collection and treatment, in some ways advancing beyond the EU’s Council Directive 98/83/EC.1
Waterways themselves can innovate. When the Roman Aqueducts were built, it was due to an increasingly polluted Tiber River. When London’s water supply from the Thames became problematic, a public-private system was developed: the New River. Will the Grand Canal of China, part of the Belt and Road Initiative, lead research and action to improve the aquatic environment ? Might Inland Waterways International champion ways to improve the health of rivers and other created waterways?
SOLUTION: YOU – What can you do?
Don’t purchase bulk or volume packaging, avoiding accumulation of unused or expired chemical formulations.
Never flush unused medications, vitamins, or supplements down the drain.
When you must dispose, trash/landfill is preferable to flush/water. First, remove pills from container (recycle container), then crush the pills, add a bit of water, and seal the result in a strong plastic bag before placing in trash.

Rivers and canals of Jakarta, Indonesia. Image: wikimedia.
MOVING THE CAPITAL DUE TO SEA RISE: Jakarta, Indonesia is the fastest sinking city on earth. Sea rise threatens the city, located on land intersected by 13 rivers. A busy port, Jakarta is congested and dense; heavy port buildings weigh down the terrain. As the capital, Jakarta also supports government, industry, and a burgeoning population. Residential and industrial water needs result in considerable pumping from the rivers, further draining the land mass. Another burden of density: traffic – Jakarta’s is among the world’s worst. And then there’s the residential buildings: 10 million people call Jakarta home, making it one of the world’s megacities. Skyscrapers dot the skyline, adding weight. Jakarta has sunk eight feet in the past decade, and the subsidence continues. Half of the city is below sea level.
Baghdad, surrounded by the Tigris River. Image: wikimedia.
NEW CAPITAL, NEW VISION: Changing the capital of a country is not unique in history. Baghdad was founded with a new vision, drawn as three concentric circles with a stroke of the Caliph’s sword marking the new capital. As Baghdad rebuilds, will Frank Lloyd Wright‘s plans and drawings bring Al Mansur’s vision to life as Madinat as-Salam, “City of Peace?” Other times, capitals moved inland from ports: Lagos, a port city, begat Abuja, moving Nigeria’s capital to a central location designed with vision and values including Haussmann’s Paris and L’Enfant’s and Banneker’s Washington, D.C. Rio de Janeiro ceded its position as capital to Brasilia, in part because the city of Ipanema beach became too dense; coastal location also meant vulnerability. The new capital, Brasilia, was central to the diverse country, representing a wider vision. Lucio Costa designed the new capital to be built in the shape of an airplane; Brasilia was the first city built to be seen from the air.
Costa’s Plan for Brasilia, in the shape of an airplane. Image: Library of Congress.
NEW BALANCE OF POWER: Just as Brazil chose an inland location, and Nigeria selected Abuja to relate to the center of the country, so Indonesia’s possible choice of an area of Borneo might represent a wider view. Palangka Raya is in consideration, in part due to a previous proposal by first president (1945-1967) Sukarno.
FUTURE OF COASTAL LOCATIONS IN CLIMATE CHANGE: Jakarta is a case example of the future. Rising seas may inundate some of the greatest cities in the world, many built as ports. As Indonesia begins to move its capital away from Jakarta, it will rebuild the coastal metropolis to defend from sea rise: “By 2050, about 95% of North Jakarta may be submerged,” according to Heri Andreas, Bandung Institute of Technology. Can innovations such as those proposed by Lempérière and Deroo to use canals, and rivers, to combat rising seas, help Jakarta and other port cities build a safer, better future? Will the Belt and Road Initiative build very different kinds of ports, using rivers, canals, and urban harbors to address sea rise?

Climate change is causing sea rise resulting in coastal erosion, flooding, and threatening ports and cities. Jakarta is in extreme danger: thirteen rivers run through the city, causing frequent flooding. The mega-city of 10 billion is doubly endangered: urban land is suffering subsidence, parts of Indonesia’s capital (some predict 95%) could be deluged by 2050.
Even rivers like the Thames and Lea in London are not immune. But the city of London Bridge is responding. Thames21 is planting reeds that oxygenate rivers, restoring the habitat marred by pollution; reeds convert toxic ammonia to nitrate. Reed beds also provide habitat for aquatic life. In an echo of theCanal des Deux Mers, the canalized section of the River Lea will receive new reed beds every 300 meters over the length of the river coursing through London.

Meanwhile, Jakarta is exploring response including artificial recharge, a method used a half-century ago by Tokyo in a time of subsidence; to support the program, groundwater extraction was halted and businesses were required to utilize reclaimed water. Jakarta would need to use only rainwater; could catchment systems help? The Dutch, formerly involved in the region, have returned: Institute Deltares reported on the efficacy of the current plan to build the Great Garuda Sea Wall (32 km) along with 17 artificial islands at the cost of (US$) 40 billion. Included in the plan is a new lagoon waterway that can be lowered during floods allowing water to drain. Another method: biopori – digging a hole of 100cm depth to allow rainwater to more easily absorbed into the land, replenishing groundwater. Indonesia may offer an example to many places in the world surrounded by water; how can we build better coasts?

“Green 8 in a Sea of Blue.” Earth Observatory Image: https://eoimages.gsfc.nasa.gov.
Seen from space, the Americas look a bit like a green 8 in a sea of blue. One glance reveals our planet is made of regions, not nations. Rivers do not stop at lines arbitrarily drawn on a map: transboundary waters are shared resources. Another interconnection: land use, including transport. Great rail systems of history such as the Trans-Siberian or Canadian Pacific railways redefined connection through rapidly advancing transit technologies. Now, electric highways, autonomous vehicles, and hyperloop transit could link continents in innovation.
In 2018, Canada, Mexico, and the United States debate the North American Free Trade Agreement (NAFTA). Negotiations should include transboundary water resources; legal precedent of the Colorado River Compact may help address current considerations. Nafta truckers could pioneer automated highways that might steer negotiations. But Nafta may be too small to address macro issues.
Is it now time to extend the north american discussion, to a broader regional scope? Afta Nafta. Decisions about water quality in one nation may impact another; transit links continents, not countries. Oceans may ultimately determine the fate of cities: from Natal to New York, many are coastal. What if everyone in the Americas learned at least one of the languages of their neighbors? Language-basededucation and cultural exchange might stir innovation in areas such as shared water resources, intelligent highways, public health, and rights. Could there be a regional tour of beauty, instead of a tour of duty? Xchange students and volunteers could form corps maintaining readiness for disaster response (by definition, regional) while practicing environmental service, in an updated CCC of the Americas. Potential logo? Green 8 in a Circle of Blue.
It might be noted that 8, viewed on the horizontal plane, is the infinity symbol. System scientists may suggest that two interconnecting loops could form a renewing system. The infinity symbol was the creation, in 1655, of John Wallis (he also served as chief cryptographer for Parliament). Whether it remains infinite or not, our shared environment depends upon our actions. Perhaps it is time to dedicate at least one year, per decade, to improvement of our shared resources: celebrate the 8’s by honoring interconnection.

Caño Martín Peña may offer a vision for the future. Help Puerto Rico now. Image: wikipedia.
Caño Martín Peña stretches 3.75 miles linking wetlands and canals to rivers meeting the sea of San Juan Bay, Puerto Rico. In 2004, eight communities along the canal incorporated to protect the canal, and dredge the channel; in 2015, the Environmental Protection Agency and the Urban Waters Federal Partnership issued a nueva vida – new life- vision for the canal. Rebuilding Puerto Rico, after recent hurricane destruction, may increase awareness of canals in flood mitigation. According to Inland Waterways International, canals create economic and environmental benefits, as well as locally-generated electric power. The World Canal Cities Organization recently met in Shaobo, China to explore the Grand Canal, busiest in the world, and building block of the Belt and Road Initiative. Panama and Suez are also notable. The Erie Canal opened the United States to a new era of development; the New York Canal Corporation worked with the World Canals Conference to host the 2017 conference on the Erie Canal in Syracuse, New York. What should the future hold for the world’s canals? How might Puerto Rico lead the way? Enlace and the Caño Martín Peña Ecosystem Restoration Project aim to improve 6,600 acres of the San Juan Bay, and the lives of those near its waters. In the future, canals may help coastal cities weather rising seas, allowing the water in as in Rotterdam. Meanwhile, Puerto Rico looks for help now, and leadership in the future, perhaps including a new vision of canals.

The waters announced their engagement in 1817 but would not be wedded until 1825. Upon the bicentennial of the Erie Canal, concert tours by water will ring celebratory along the route credited with shaping the economic and political destiny of the United States. Historians say the Erie Canal may have been inspired by Robert Fulton, of steamboat fame, who admired the Canal des Deux Mers in France. Once the engagement’s union was fulfilled, in the “wedding of the waters,” the Erie Canal was an instant success. Shipping goods from Buffalo to New York City before, required two weeks; via the canal, three days. Similarly, the cost of transporting goods by land, formerly $100 per ton, was now reduced to $10 per ton. What are the waterways of the future? Such considerations will be explored at the World Canals Conference, convening this year in Syracuse, New York, on the Erie Canal.
