How can humans intervene to restore to life a "Dead Zone" in a Coastal area?

I live near a beach that has changed a lot over the years. I used to smell the salt water and hear the gulls, the waves were teeming with sea life. Now the water is brown, the salt smell is gone and I rarely see a gull. They've gone inland to look for food. *Galveston, TX* If people CAUSE a problem then it is reasonable, not ironic, to ask what people can do to FIX it.

1. The Dead Zone in the Gulf of Mexico that you are referring to is caused by agricultural runoff that is transported down the Mississippi River and dumped into the Gulf. Humans on a governmental scale could stop giving subsidies to massive agribusiness corporations and industrial farms who are the primary cause of this situation. On the individual level, humans can do things that make themselves less reliant on the products that are produced by these mega farms. Local agriculture, organic produce, and reduced meat consumption are all individual actions that would create a slow shift towards a less desiccated Gulf Ecosystem.
2. Stop spraying Petro-chemicals on the watershed.

4. Is the irony lost here? How can humans intervene so that we can radically effect change in an area? I thought that was the problem to begin with.
