Commenting on the oil spill, Rush Limbaugh said ““The ocean will take care of this on its own if it was left alone and left out there. It’s natural. It’s as natural as the ocean water is.”
Rush is actually right.
First, oil will eventually break down through natural processes. However, this will take a rather long time and the oil will do considerable damage in the meantime. Given Rush’s logic, we should say the same thing about things like dirty dishes and garbage in our houses. After all, natural processes will eventually take care of the food on the dishes and the garbage in the house. So, why bother with those things? Also, natural processes will eventually take care of any illness (this might involve death, of course), so why mess around with medicine?
Second, oil is natural and is as natural as the water. After all, we do not make the oil that we drill for-we simply find it after it has been produced by natural processes. Of course, being natural does not mean that something is not dangerous. Cyanide, rattlesnake venom, red tide, earthquakes, volcanoes, and gamma rays are all natural. Yet they are rather dangerous. The fact that something is natural does not mean that we should not be concerned about it showing up on our beaches.
You know, Rush, it doesn’t make you a tree hugger if you accept that an oil spill is bad. Even the folks in the oil companies are willing to admit this.

The whole quote:
“You do survive these things. I’m not advocating don’t care about it hitting the shore or coast and whatever you can do to keep it out of there is fine and dandy, but the ocean will take care of this on its own if it was left alone and was left out there,” Limbaugh said. “It’s natural. It’s as natural as the ocean water is.”
So, he is basically saying we should keep the oil away from shore but not worry too much about the oil in open water.
Oil in the ocean is still a problem. Looking at it purely in economic terms, it will do considerable damage to the fishing industry in the area. Of course, it must be pointed out that we do not have very effective ways of dealing with the oil spill. As such, we might just have to go with Rush’s plan-let nature deal with it.
No two oil spills are the same because of the variation in oil types, locations, and weather conditions involved. However, broadly speaking, there are four main methods of response.
(1) Leave the oil alone so that it breaks down by natural means. If there is no possibility of the oil polluting coastal regions or marine industries, the best method is to leave it to disperse by natural means. A combination of wind, sun, current, and wave action will rapidly disperse and evaporate most oils. Light oils will disperse more quickly than heavy oils.
(2) Contain the spill with booms and collect it from the water surface using skimmer equipment. Spilt oil floats on water and initially forms a slick that is a few millimeters thick. There are various types of booms that can be used either to surround and isolate a slick, or to block the passage of a slick to vulnerable areas such as the intake of a desalination plant or fish-farm pens or other sensitive locations. Boom types vary from inflatable neoprene tubes to solid, but buoyant material. Most rise up about a meter above the water line. Some are designed to sit flush on tidal flats while others are applicable to deeper water and have skirts which hang down about a meter below the waterline. Skimmers float across the top of the slick contained within the boom and suck or scoop the oil into storage tanks on nearby vessels or on the shore. However, booms and skimmers are less effective when deployed in high winds and high seas.
(3) Use dispersants to break up the oil and speed its natural biodegradation. Dispersants act by reducing the surface tension that stops oil and water from mixing. Small droplets of oil are then formed, which helps promote rapid dilution of the oil by water movements. The formation of droplets also increases the oil surface area, thus increasing the exposure to natural evaporation and bacterial action. Dispersants are most effective when used within an hour or two of the initial spill. However, they are not appropriate for all oils and all locations. Successful dispersion of oil through the water column can affect marine organisms like deep-water corals and sea grass. It can also cause oil to be temporarily accumulated by subtidal seafood. Decisions on whether or not to use dispersants to combat an oil spill must be made in each individual case. The decision will take into account the time since the spill, the weather conditions, the particular environment involved, and the type of oil that has been spilt.
(4) Introduce biological agents to the spill to hasten biodegradation. Most of the components of oil washed up along a shoreline can be broken down by bacteria and other microorganisms into harmless substances such as fatty acids and carbon dioxide. This action is called biodegradation. The natural process can be speeded up by the addition of fertilizing nutrients like nitrogen and phosphorous, which stimulate growth of the microorganisms concerned. However the effectiveness of this technique depends on factors such as whether the ground treated has sand or pebbles and whether the fertilizer is water soluble or applied in pellet or liquid form.
From the Univ. of Delaware. Rush’s response is in line with #1.
