The Peshtigo Fire of 1871

Artist's Rendition of Pre-Fire Peshtigo
           These days, with the climate warming and weather changing, it is becoming increasingly common to hear about wildfires both in the United States and abroad. Australia is plagued with fires as their inner regions warm and dry up. In the US, California and other western states are struggling to keep wildfires at bay despite higher temperatures and less rain. It would make sense to assume that the deadliest fire in the history of the United States took place there, however, it did not. Its location was far cooler: Wisconsin surrounding the village of Peshtigo.

U.S. Weather Bureau Map - 8 Oct 1871
            The wildfire took place in 1871 in northeastern Wisconsin and into Michigan. The weather conditions that summer were perfect for fires. There had been droughts and unusually high temperatures throughout the country, causing the parched landscape to become a giant tinderbox. On October 8, a cold front started to move through the region. The strong and steady breeze fulfilled the last factor needed to make any fire that happened huge. A total of five separate fires were sparked across Michigan, Illinois, and Wisconsin that day, the most famous of which was the Great Chicago Fire, however none of these fires had the same intensity of the Peshtigo fire.

            There are a number of ways that the initial spark that started the deadly blaze could have originated. The area depended on agriculture and lumber for its income. In farming, it was commonplace to burn small sections of land to clear them, one of which could have started burning out of control. The area lumber mills kept great amounts of raw lumber around them and also produced sawdust and bark as waste. In such dry conditions a stray spark from a saw could have ignited the blaze. Additionally, sparks from train wheels could have lit dried grass around the track. Whatever the source, once the blaze started, it grew uncontrollably on the plethora of dried objects that it could easily burn. Bucket brigades were no match for these beasts.

            Before the terrified residents knew it, they were dealing with a massive fire. Strong winds caused the fire to move at perhaps 40 to 50 miles per hour and develop into a firestorm. The blaze reached five miles wide and by some estimations, a mile high. Even the people on the other side of the bay were not safe, as the firestorm jumped more than ten miles across Green Bay. Even more terrifying were the fire tornadoes that developed during the chaos. One whirled through the village of Peshtigo, flattening and incinerating everything in its path. The residents of another town close to Peshtigo tried to flee, however they either burned to death while running or boiled as they tried to shelter in a small river.

            When the fire ended, it had burned 1.2 million acres and killed an estimated 1200 to 2500 people. The exact number is unclear, as some towns were burned so completely that there was no one left to identify bodies or give an estimate of how many lived in the area. Nearly 350 people, about half the population of Peshtigo, was buried in a mass grave near the town. The desolation was so complete that many left the area rather than live among the painful memories. Accordingly rebuilding was slow. The state government was not in session so the only immediate aid that got to the town was a train car load of supplies commandeered by the wife of the governor. Eventually the residents received some government assistance but it was too little too late; their lives had already been charred beyond recognition.

The Peshtigo Fire as depicted in Harper's Weekly            A fire of this magnitude is unlikely to happen again in the United States. The ability to fight fires in planes and the practice of controlled burns to prevent larger fires have made conditions exponentially safer. In addition, better communication systems and faster response before and after wildfires can save many of those caught in these dangerous situations.

Bananas: More Than You Ever Wanted to Know

 


                The banana. Possibly the humblest of fruits. So regular to us that we seldom think about how this tropical product gets to our thoroughly un-tropical area. As it turns out, the banana is actually an amazing representation of diffusion of a product and globalization of consumption. To realize the full extent of the banana’s global takeover, we must start 15,000 years ago in the tropical forests of Papua New Guinea.
Native Banana

  The banana that we know today is almost completely unrecognizable from its native counterpart. The fruit that is now easily peeled, seedless, and sweet was considerably less luxurious in its native form. In fact it was full of seeds and the peel was fairly difficult to remove. However, the people of the Kuk valley in current Papua New Guinea domesticated the fruit, slowly decreasing the size of the seeds and increasing the amount of edible flesh. In fact, some of the banana plant’s seeds were bred to be so small that the plant became largely asexual. From this early start, the cultivators spread the plant throughout the surrounding islands and eventually to mainland Asia and northern Australia. In some cases, they seemed to simply plant the bananas and promptly leave the area, only to rediscover the plant years later growing wild. Through this process, the peoples of mainland Asia discovered, cultivated, and incorporated the banana into their culture.
 
                As time progressed, more selective breeding of the banana took place in Asia and eventually India. Some varieties were bred to eat, others to harvest fibers for cloth, and still others to have large leaves. In this way, the banana became an integral part of the culture of the Far East. As the Middle and Far East started to trade more extensively, the banana kept moved farther west. With the rise of Islam and the moors, the banana moved ever further and reached Northern Africa and Spain around 1200 AD. The fruit was further popularized here as more people came in contact with it, though few that lived outside the banana’s growing areas could find it.
 

Ugandan Banana Plantation
                The age of discovery brought the banana to its final destination, the Americas. As it was a tropical plant, Spanish conquistadores brought bananas along in their journeys. From here, banana plantations, whether run by slaves or communities, popped up around the Caribbean and in South America. From this point, bananas were grown as either a subsistence or a local sale crop in the Americas.

                So the banana is now known on every inhabited continent. What could be next? The answer is slow but steady expansion. As the banana spread to every viable growing location (tropical climates, hot and wet), the ability of people to transport crops also grew. In this way, bananas became one of the most internationally intertwined fruit, as many countries are growing them and even more are consuming. Fast forward now to around the year 1900. There are significant banana crops being grown in Australia, India, tropical Africa, and many countries in Latin America. The world is now connected by many kinds of transportation, making goods and information travel much more smoothly. There is now such a thing as international competition in banana trade. When there is a profit to be made, there is always a company that rises to the top. For bananas, this company is United Fruit. The company flourished throughout the next 70 years despite, or because of, the questionable business decisions it made.
 
                For instance, United Fruit was a company largely responsible for producing accurately named “Banana Republics,” countries that rely extremely heavily on one export. United Fruit largely controlled a few of these countries including Guatemala, Honduras, and Costa Rica by establishing a trade monopoly. They then had enough power and influence to basically control the internal politics of the country to reflect the goals of the company. This led to numerous cases in which the rights and needs of workers were being ignored by the large company that controlled them.
 
                As do many companies that seem to be unstoppable, the opposite is true. After only 70 years in power, decline in profits, caused in part by Standard Fruit Company (eventually Dole), United Fruits merged with another company. This merger would eventually become Chiquita. Here begins a trade war between two multinational corporations that will do anything to ensure uniform quality and low cost of fruit. But neither is prepared for the challenges ahead.
 
                So remember near the beginning of the article when the indigenous Papua New Guineans bred bananas to have such small seeds many became asexual? Good news right? Wrong. This also makes the banana one of the most fragile fruits in terms of susceptibility to pathogens. This is because through asexual reproduction, all the banana plants (not trees as they are actually giant herbs), share the exact same genetic material. If a pathogen finds its way to a banana plant and the plant has no immunity, it is not just the plant that dies, the disease will spread throughout the entire plantation, country, and (this has happened before) world. In the 1950s, as the national corporations vied for the best prices and growing locations, they were all struck with a banana virus that spread quickly from country to country. In a matter of a decade, all farmers were forced to change varieties of bananas as they were unable to stop the virus. The new plant type had resistance to the virus but the fruit was not nearly as good. Just think about that when you are eating your next banana. You are eating the world’s second choice.
A real bummer. The fungus is everywhere.

                But this problem does not stop there. The current type of bananas grown around the world are being attacked by what is called Panama Disease, a deadly fungus. It is devastating banana crops and threatening to wipe out the currently preferred species of banana. More bad news, there is really no good backup species. When these bananas are gone, we could have reached the end of commercial banana growing.
 
                This brings us to the impact of banana’s globalization. It has really done a lot to change the world. Poor tropical countries around the world grow bananas as a way to get into the international market, though they often endure terrible working conditions and unfair business practices from large corporations when doing so. Some countries rely so heavily on their export that the banana buying companies have major influence in their governments, earning them the title of a banana republic. Bananas have also helped alert the world to the problem of monoculture in agriculture. When only one type of banana is grown and something bad happens to that type, there is not an easy way to instantly switch all the crops to another variety. An enormous economic collapse of that product usually ensues, which is beneficial to no one. To combat this, plantation owners should try to diversify crops to ensure that there is not a complete collapse in the event of a world-wide banana disease. 
                Long story short, bananas are a perfect example of globalization. They were once an unpleasant little herb growing on a hot, wet, jungle-covered island. They were domesticated, transported, artificially selected, diffused, and universally accepted into cultures around the world. Despite their easy conquering of the continents, they are in danger because of monoculture and a sneaky little fungus by the name of Panama Disease. You honestly could have read this paragraph and lived the rest of your life without regret. Just go. Eat a banana and really try to enjoy it. You may not be able to for long.
