River stages, in their wide variations, became generally higher through time, as the water was presented with fewer outlets. People began to wonder if the levees could ever be high enough and strong enough to make the river safe. Possibly a system of dams and reservoirs in the tributaries of the upper valley could hold water back and release it in the drier months, and possibly a system of spillways and floodways could be fashioned in the lower valley to distribute water when big floods arrived. Beginning in the eighteen-fifties, these notions were the subject of virulent debate among civilian and military engineers. Four major floods in ten years and thirty-two disastrous crevasses in a single spring were not enough to suggest to the Corps that levees alone might never be equal to the job. The Corps, as things stood, was not yet in charge. District by district, state by state, the levee system was still a patchwork effort. There was no high command in the fight against the water. In one of the Corps’ official histories, the situation is expressed in this rather preoccupied sentence: “By 1860, it had become increasingly obvious that a successful war over such an immense battleground could be waged only by a consolidated army under one authority.” While the Civil War came and went, the posture of the river did not change. Vicksburg fell but did not move. In the floods of 1862, 1866, and 1867, levees failed. Catastrophes notwithstanding, Bayou Plaquemine—a major distributary of the Mississippi and a natural escape for large percentages of spring high water—was closed in 1868, its junction with the Mississippi sealed by an earthen dam. Even at normal stages, the Mississippi was beginning to stand up like a large vein on the back of a hand. The river of the eighteen-seventies ran higher than it ever had before.

But, the environment is really the whole planet on which we live. Everything (winds, trees, animals, insects, people, etc) forms part of the living system of earth. For example, trees are important because they make oxygen which helps us breathe. If too many trees are cut down for firewood or furniture this reduces the amount of oxygen going into the earth's system. Over time, this can have a very bad effect on people and animals. These are some examples of what is happening to the earth because it has been exploited and not protected: weather patterns have changed, there are more droughts and more floods, the temperature is rising and most important, the ozone layer that should protect us from the dangerous rays of the sun has been damaged and does not work as effectively as it did before.
So, it is important to protect the environment from being exploited and it is the reason why people now talk about the term sustainable development.

Just why the Army should be involved at all with levee systems, navigation locks, rock jetties, concrete revetments, and the austere realities of deltaic geomorphology is a question that attracts no obvious answer. The Corps is here because it is here. Its presence is an expression not of contemporary military strategy but of pure evolutionary tradition, its depth of origin about a century and three-quarters. The Corps is here specifically to safeguard the nation against any repetition of the War of 1812. When that unusual year was in its thirty-sixth month, the British Army landed on the Gulf Coast and marched against New Orleans. The war had been promoted, not to say provoked, by territorially aggressive American Midwesterners who were known around the country as hawks. It had so far produced some invigorating American moments (“We have met the enemy and they are ours”), including significant naval victories by ships like the Hornet and the Wasp. By and large, though, the triumphs had been British. The British had repelled numerous assaults on Canada. They had established a base in Maine. In Washington, they had burned the Capitol and the White House, and with their rutilant rockets and airburst ballistics they tried to destroy Baltimore. New Orleans was not unaware of these events, and very much dreaded invasion. When it came, militarily untrained American backwoods sharpshooters, standing behind things like cotton bales, picked off two thousand soldiers of the King while losing seventy-one of their own. Nonetheless, the city’s fear of invasion long outlasted the war.

Then, in the fall of 1972, the winter of 1973, river stages were higher than normal, reducing the system’s tolerance for what might come in spring. In the upper valley, snows were unusually heavy. In the South came a season of exceptional rains. During the uneventful era that was about to end, the Mississippi’s main channel, in its relative lethargy, had given up a lot of volume to accumulations of sediment. High water, therefore, would flow that much higher. As the spring runoff came down the tributaries, collected, and approached, computers gave warning that the mainline levees were not sufficient to contain it. Eight hundred miles of frantically filled sandbags were added to the levees. Bulldozers added potato ridges—barriers of uncompacted dirt. While this was going on, more rain was falling. In the southern part of the valley, twenty inches fell in a day and a half.
