So abused, so neglected, so forgotten.

The oil spill currently afflicting the Louisiana coast has received a great deal of attention. This media focus happens all too rarely in such an important part of the nation.

The Gulf Coast is one of the most beautiful and ecologically rich areas of the United States. A tremendous amount of our seafood intake comes from the region. Shrimp, crayfish, and oysters breed in the swamps’ brackish waters. These animals have fed Gulf residents for millennia and make up a significant part of our seafood diet today.

The marshes also serve a vital role for birds. Not only do many species breed in the swamps, the marshes are the first stop for exhausted birds migrating over the Gulf of Mexico from Latin America.

The coastal swamps are home to the nation’s only populations of American alligators and other reptilian species. While conservation programs have helped alligator populations recover since the 1960s, decreased and degraded habitat places their long-term future in question.

The bayous have an important human history as well. French Catholics fled to Louisiana in the 1760s after the British takeover of Canada. Living and working in the isolated bayous for over two centuries, the Cajuns created their own musical and food traditions, their own version of French, and a vibrant culture that have fascinated Americans past and present.

Mike Tidwell’s superb 2003 book Bayou Farewell: The Rich Life and Tragic Death of Louisiana’s Cajun Coast lays out the damage we have done to this fragile ecosystem and social system. For decades, we have ignored, drained, starved, industrialized, and destroyed this vital habitat of American ecology and society.

In order to contain flooding, the U.S. Army Corps of Engineers has constructed levees to keep the rivers in its banks. The floods provided sediment that recharged and expanded the marshlands. Today, all of that sediment washes out to sea.

To improve transportation, the oil industry cut shipping channels through the bayous. The engineers did not know that once created, the canals would eat away at the marshes, created huge expanses of salt water in the former marshes.

Without the nourishing sediment and with the canals, the bayous are melting away. Each day, we lose 25 acres of land. Southern Louisiana is in danger of disappearing. The ocean eats away at the marshes every day the sediment does not replenish them. Entire towns have fallen victim to oceanic erosion.

When the bayous go, the wildlife disappears as well. That includes the shrimp, crayfish, and oysters that make up Louisiana cooking and much of the state’s economy. Within decades, the bayous, which have nurtured Native Americans and Cajuns for centuries, may disappear.

To date, the greatest manifestation of this environmental damage came in the form of Hurricane Katrina in 2005. These coastal marshes provided a buffer zone for New Orleans. Hurricanes hit the marshes and lost their power in the fifty miles between the open water and New Orleans. Without those wetlands and their ability to both soak up water and weaken storms, Hurricane Katrina hit the Gulf Coast at full force, devastating the area and causing the levee breaches that drowned New Orleans.

Now we have the oil spill. This disaster will exacerbate the region’s problems. It will devastate the fishing industry. It could kill millions of birds, some of which are endangered species. Spring is the migration and breeding season and thus the spill’s damage to birds will be more far-reaching than if it happened in December.

But perhaps we can find a silver lining in this catastrophe. American reliance on oil imports means that we can remain ignorant about drilling’s effects. Not since the Santa Barbara, California oil spill of 1969 has a major spill affected the Lower 48 states. That previous incident helped shape the environmental movement that created the first Earth Day in 1970 and a tremendous amount of legislation during the next decade which cleaned up our rivers, air, and soil, placed industries under new regulations, and led to the recovery of many endangered species.

Moreover, the 1989 Exxon Valdez oil spill in Alaska turned much of the American public against oil drilling in our most beautiful places. Memories of this event and the millions of dead birds, seals, and fish made it impossible for George W. Bush to open Alaska’s Arctic National Wildlife Refuge (ANWR) to drilling. Yet none of this has dampened Americans’ zeal for consuming foreign oil, where we can’t see the consequences.

Perhaps then it is better that the oil spill happened in the United States instead of Nigeria, Saudi Arabia, or Venezuela. A giant spill and subsequent environmental disaster means nothing to most Americans if it happens far away. The oil industry has created ecological and human catastrophes across the world for a century. But we keep driving our vehicles, oblivious to our impact upon the world. Seeing that damage in the form of oil-covered herons and alligators may create a moment for serious reflection of our actions.

Hopefully, the oil spill will make President Obama rethink his decision to open up parts of the Atlantic Coast to oil exploration. Although elected on a clean energy platform, Obama’s energy policy has in fact favored development. He has not shown a real commitment to clean energy in the form of legislation or executive policy. I call for President Obama to use this tragedy as inspiration both for a comprehensive energy bill and for renewed environmentalism at the federal level with far-reaching legislation rivaling that signed by Presidents Johnson, Nixon, and Carter.

Realistically, the marshes’ disappearance may prove easier to solve than the oil spill’s long-term implications. We can recreate the marshes by removing the levees and allowing the sediment to replenish the land. Scientists have successfully done this in small regions and almost immediately the alligators, fish, and birds return. But weaning the nation off oil is a fantastically difficult task. And no matter how rigorous the regulations, oil spills will happen.

As long we mine the waters off the Gulf Coast for oil, the bayous and all the people and wildlife that rely on them remain in peril. So long as we remain reliant upon oil, versions of the Exxon Valdez and the Gulf Coast spill of 2010 will happen somewhere around the world almost every year.

It’s also the amount of time that has passed now since Hurricane Katrina swept across the Gulf Coast and devastated the city of New Orleans, driving thousands of citizens from their homes. Many still have not been able to return.

I spent four years of my life in New Orleans. They were four years that shaped me into the person that I am today. I learned about racism and I learned about jazz. I learned about poverty and class divisions, and I learned about real friendship. I learned what it was like to really fear your home being wiped out by a hurricane, and I learned what it was like to struggle to pay rent. I haven’t been back, but the city remains in my heart.

After the storm, many Americans opened their hearts (and in some cases, their homes) to New Orleans. We have a new president now, perhaps partly because Katrina exposed George W. Bush’s basic incompetence and lack of empathy. Those of us who have been paying attention have gotten quite an education from the government’s handling of Katrina, watching the initial fumble grow into four years of neglect.

According to James Perry, Executive Director of the Greater New Orleans Fair Housing Action Center and candidate for mayor of New Orleans, the Obama administration has made an effort to do better by New Orleans. He notes, though, that, “The thing that’s difficult about that for Louisianans and New Orleanians is that four years out, we’re tired of waiting.”

And New Orleans is still waiting. The levees are just now testing at pre-Katrina strength—the same levees that failed the city under only an indirect hit from the storm. Much stronger protection is needed, not just in the form of levees, but the wetlands that would have provided a barrier to a storm surge had they not been devastated years before the hurricane came. Perry says, “Not having proper levee protection frankly makes a lot of people afraid for the future of the city.”

The lack of affordable housing has kept many New Orleanians away and keeps others struggling. Neil Abramson, Louisiana State Representative from New Orleans, notes “We recently have had an increased, visible homeless population. The federal government has sent us ‘homeless vouchers’ but they are only available 5 per week.” He also says that with the August 31 expiration of federal housing vouchers, “we could have a lot more homeless people as those people receiving housing under that program will lose it.”

The Katrina cottages, small permanent houses that could serve as a base for rebuilding lost homes, have been stalled for years now. Perry says, “I’m tempted to say ‘What cottage program?’ It’s a testament to the way that government hasn’t performed after the storm.” Abramson says that $74.5 million in federal money was allotted to the program, which called for the building of 500 approximately 900 to 1300 square foot model homes as an alternative to FEMA trailers.

Only one “exemplar” trailer has been built so far, according to Abramson, who is holding legislative hearings on the subject. He reports that now two-thirds of the cottages are under construction with completion dates staggered over the next 8 months. He agrees with Perry though that, “In sum, the cottage itself might turn out to be a good product, but the State has completely botched the ‘process.’ Four years post-Katrina is absurd.”

Part of the appeal of New Orleans for years, the draw for creative people from around the world, was its incredibly cheap rent. In 2000, only 46% of the city owned their own home, yet rental apartments and public housing were affordable even for the city’s low income (the median for a household in 2000 was $27,000). But according to Perry, Katrina wiped out 80,000 units of housing, and the department of Housing and Urban Development, under Bush, demolished 4600 more, bulldozing public housing that was home to the city’s poorest citizens.

Section 8 housing vouchers are another center of controversy—Perry notes that a large majority of landlords won’t accept the vouchers, and complain of the failures of the housing authority. This week, the head of the Section 8 program stepped down amid allegations that he was using the vouchers himself despite his $100,000 salary.

Rents are not as steep as they were in the immediate aftermath of the hurricane, when Perry says they were higher than New York City’s, but they remain 40% higher than before the storm. Needless to say, in a town that survives on tourist dollars, incomes haven’t kept up, and the recession certainly hasn’t helped.

The city’s hospitals continue to suffer—Abramson notes that Governor Bobby Jindal used his line-item veto to cut funding for the New Orleans Adolescent Hospital, the only state-run mental health facility. “That will cause a crucial lost of mental health services, potentially increase crime, likely cause jail overcrowding, and possibly hurt our private and non-profit hospitals who might be forced to treat these patients without compensation,” he says.

Charity Hospital, one of the nation’s oldest public aid hospitals, relied on for care by thousands of New Orleans residents, remains closed after the storm in another blow to the low-income citizens of the city.

After Katrina, Barbara Bush famously said, “And so many of the people in the arena here, you know, were underprivileged anyway, so this–this is working very well for them.” It is hard to see, four years in, how well things have worked out for people who lost everything they could rely on. Instead, it often appears as though the government is conspiring against them, and right-wing radio hosts can barely hide their glee. Neil Boortz sneered at them on Twitter, referring to “the debris that Katrina chased out.”

The thing that’s always kept New Orleans going is its music; it has always been the life and soul of the city. Ron Rona, of the band the New Orleans Bingo! Show, says that the music scene is undergoing a resurgence. He credits the rise of social networking and Internet marketing–“In some ways, it’s kind of leveled the playing field as far as promotion goes to an internet savvy set of hungry music fans.”

Music education has always been a strong part of the city as well—it has kept the jazz scene vital and strong, passing down the traditions and bringing new blood in to innovate. Rona points to new programs that have sprung up in the past few years, including the Roots of Music Foundation, founded by Derrick Tabb, snare drummer in the world-famous Rebirth Brass Band.

“What’s missing?” Rona asks. “The refocus of the national spotlight on one of the most unique and vibrant musical heritages in the world. And not just because we went through a storm.”

Four years is a long time and much has changed. The recession that has spread across the world has forced people to look after themselves and cut back not just on giving but on travel and entertainment, the very industries that keep New Orleans going. It is easy to forget the tragedy that befell New Orleans, or to assume that no news is good news, that the government is working as it should to rebuild the city, or that private industry and charitable organizations have filled in the gaps.

Abramson, Perry, Rona and thousands of New Orleanians like them are working hard to rebuild their city from within, but without support from the federal government, they will continue to struggle. Hurricane Katrina’s devastation defined the end of the Bush era; helping to rebuild a thriving New Orleans can help define the Obama years.
