Sea weed does, in this article I have stumbled upon.
Researchers have found that these chemicals are fatal for coral just by contact.
usually the sea weed is in control by herbivorous fish but lately due to over fishing… the population of the sea weed has risen and the population of the fish have dropped drastically.
In studies performed by the early edition of the journal Proceedings of the National Academy of Sciences (PNAS). The research was supported by the National Institutes of Health, the National Science Foundation, and the Teasely Endowments at the Georgia Institute of Technology. Researchers have reported “Between 40 and 70 percent of the seaweeds we studied killed corals,” said Mark Hay, a professor in the School of Biology at Georgia Tech. “We don’t know how significant this is compared to other problems affecting coral, but we know this is a growing problem.
Coral reefs are at an all time low and at this rate there will be no such thing as a coral reefs. so many contributors are reason to this.. some naturally and some man made.
1. How do you think this is a problem?
2. How can you help solve this problem?
I have recently read in this article http://www.sciencedaily.com/releases/2010/03/100302083451.htm that the sea squirt can actually put a prevention on the spread of alzheimer’s disease by actually making a protein forming plaque that actually prevents the disease from spreading to any harsher more serious stages… lately I have had reason to believe for every land caused disease, in the water there is a cure for it… 70 % of the earth is water so 30 % of the earth is land… the ratio is about a 2/3 so for ever 1 disease I think there could be a cure.
1| Could sea squirts become extinct from over harvesting..
2| What is your opinion on Alzheimer’s?
The only Penguin native to Africa is in danger of being endangered…
a 60% drop in population of these little guys has happened over the past 9 years..
due to the fact that there is a major shortage of food…
this penguin is dependent only on fish and sardines and anchovies being a major part of the South African fishing industry
is a major contribution to the reason why these birdies are getting wiped out…
the South African government has put a halt on the harvesting of these two main food sources.
in hope that the slow return of the African penguin is a good and steady one.

An QUT team of scientists are in search for an explanation to why Iron is cause harmful algal blooms. The mix of the 2 algaes usually balances out one another with the iron and water but in some cases like this one are seeming to have an effect that is causing these blooms… As far as one of the scientists on the job have to say this is what has been said,
PhD student Lin Chaofeng is studying two types of bacteria in water that “feed on” iron.
“One type of bacteria in our waterways changes iron into a dissolved state and another type of bacteria oxidises the iron and turns it back into a insoluble form which can settle on the bottom of a creek ,” Ms Lin said.
“The oxidising type of bacteria possibly makes the iron less available as a contributing factor in algal blooms. It seems that these two bacteria usually balance each other out, but sometimes the balance is upset and so I am investigating how this happens.”
All in all in my opinion I have reason to believe that there is going to be a conclusion to all of this mess.

Kelp forest’s off of Southern California, are considered one of the most diverse and productive ecosystems on the planet.
And new study shows that kelp beds are less than in the past.
Over an extensive period of time these kelp beds have gone from a vast amount to small areas of vegetation.
Over the past 20,000 years the kelp fields have been rich with life and not until about 7,500 years ago, vegetation died off due to our mis happenings.
*What would you say could help make this once lush area… non barren once again?
* Could this effect our economy?
Wild salmon and farmed salmon can now be distinguished from each other by a technique that examines the chemistry of their scales.
Recent studies have shown that the number of wild salmon are decreasing very rapidly in the Atlantic oceans and the numbers have been at an alarming rate for farmed fish @ a whopping 130,000 tons to a small hump in the graph at 5,000 tons of wild salmon. The problem with these numbers is that the number of farmed fish actually escape from fish camps and actually get mixed into the wild life eco system which causes a bad out come for the wild salmon damaging there habitat
Fish scales are formed from the same chemicals as bones and teeth and grow like tree rings, preserving a chemical record of the water the fish lived in throughout its whole life.
So this will help the fish get determined on which is wild and which is farmed.

Q 1. Do you prefer farmed or wild salmon?
Q 2. Is this something worth looking into?
