Hazards of Oil Dispersants

Facts:
Susan Shaw
*1/3 of all marine life is in danger of going extinct in 30 years
*Not dispersing oil=mangroves are hit; corals and sea grass are not
*Dispersing oil=mangroves are not harmed; coral and sea grass is
*Coral is being hit hardest
*Corexit and oil=0% fertilization with coral vs. just oil=98% fertilization
*1/4 of marine life (most of them rare) live in the coral reefs
*Corexit and oil is more toxic than either alone
*Corexit+oil=19,000x's increase in toxicity
*33 Wildlife refugees are at risk
*Gills and respiratory systems are most sensitive to toxicity
*Air-breathing mammals inhale toxic fumes which leads to pneumonia
*Foodweb will collapse

Facts:
Article
*USF found oil at the bottom of an underwater cavern
*USF believes chemical dispersants caused the oil to sink
*USF thinks sunken oil will have an effect on bottom-dwelling plankton (base of foodchain)
*USF wonders in the sunken oil can rise again?
*UGA discover oil plumes in early May
*UGA estimates that there is still 90% of the oil in the water
*UGA oceanographers and toxicologists believe that 80% of the oil is still there in some form
*The federal government hasn't taken into account the effects of methane at Macondo and oil
*Plumes aren't underwater rivers of oil-they are likely invisible and represent parts per billion of oil
*Dispersed oil doesn't mean the oil is gone," says John Hovecar.

Solving a Problem=Bigger Problem?
I think solving one problem can equal a bigger problem in different ways. One way in which solving a problem can create a bigger one, is by not necessarily creating a larger one, but, rather, by discovering a more bigger problem. As in, if you hadn't figured out Problem #1, you would've never even seen Problem #2; you had gain some information which was a key piece of info to the second complication. The second way one problem can mean a larger problem is, you screwed up trying to fix problem 1.
Your solution was one that would've been better if you hadn't even thought of it. Ex.) The BP oil spill: Corexit and the oil was more toxic than either alone and caused 0% fertilization in coral whereas just oil would've had 98%. Finally, another way that clearing one obstacle leads you to another, higher obstacle is by solving something that should've never been solved which just leads to the domino effect where one solution leads to another problem and another and another. Maybe humans should've died out long ago but we had created tools and advanced ourselves to situate ourselves to better our lives and started to withdraw ourselves from nature's laws and rule and it may end up killing everything around us . . . or we'll kill ourselves. We kept trying to solve many problems (and failing often) and if we DID solve one problem, then it lead to another. Even medicine, it leads to a larger population and if we looked at ourselves as we did other animals, we would be an over-population and be a huge hazard. But we don't (unless something HUGE happens and slaps us in the face-normally we cause it) but that doesn't mean our actions still don't have an effect; just because we refuse to see it, doesn't mean it's not there. And could this be the result of all our trials-and-errors we've done over the past years in order to, not only survive, but flourish?

Oil vs. Chemical Dispersants
This depends, are we looking at it from the mangroves' or the corals'/sea grass' point of view? If it's from the mangroves', then the oil is far deadlier; if it's from the corals'/sea grass', then the chemical dispersants are. And if it's from human's perspective (the physical, not the mental), then Corexit because it has arsenic which is known to have high cancer-causing effects. But, really, the deadliest thing are the chemical dispersants and oil together. This dynamic duo is more toxic than either alone.
