This is complete BS fear mongering. If this were true, then how did the oceans survive millions of years ago when CO2 levels were much higher than they are today? The reason is because this is complete utter BS.
Where is the implication that the ocean won't survive?
The climate, habitats, ecosystems, (the environment as a whole) have all changed countless times over the billions of years our planet has existed. Life adapts and evolves. The problem lies in that if we're changing conditions at unheard of rates (for mankind), we will end up altering the system we're accustom to and that we exploit. Even if we were to kill off most of the current life in the ocean (which no one is suggesting) new life would evolve and take its place. The problem for us is that that takes millions of years.
I like the oceans they way they are. I'd like to maintain them in their current form for the blink of an eye that I and my ancestors occupy this planet.
and if you looked at the oceans 10,000 years ago they would be much different from today
and if you looked at the oceans 100,000 years ago they would be much different from today
and if you looked at the oceans 1,000,000 years ago they would be much different from today
I very aware of this (although larger time frames are more appropriate - 10,000 years ago I imagine the oceans were remarkably similar to how they are today). That's why I said "as we know them today". I want to keep them that way since we're accustom to that and they are the current condition we exploit for our existence and comfort.

I'm not talking about climate change. I'm talking about the acidification of our oceans. Man's industrial activity directly results in the acidification of the oceans.
Anthropogenic CO2 emissions help feed the critters that build coral reefs.
Dissolved Inorganic Carbon (CO2, bicarbonate, etc.) are consumed by shell building organisms to build shells (bicarbonate) and photosynthesis in the photic zone (CO2). DIC constitute about 97% of the carbon in the oceans.
Dissolved Organic Carbon (non-colloidal bits of carbohydrates, proteins, etc.) are the mostly the product of photosynthesis. DOC can come from land or, marine sources. This is consumed by sponges which secrete food for reef building organisms.
Both DIC and DOC are part of the carbon cycle.
Anthropogenic carbon emissions (primarily CO2) constitute about 3% of the Earth’s carbon budget (~6 Gt/yr).
More CO2 in the atmosphere leads to something called “CO2 fertilization.” In an enriched CO2 environment, most plants end to grow more. The fatal flaw of the infamous “Hockey Stick” chart was in Mann’s misinterpretation of Bristlecone Pine tree ring chronologies as a proxy for temperature; when in fact the tree ring growth was actually indicating CO2 fertilization as in this example from Greek fir trees…
Enriched atmospheric CO2 “feeds” reefs in two ways: 1) Enhanced photosynthesis for the symbiotic algae; and 2) More DOC to feed the sponges that also feed reef builders as the result of enhanced photosynthesis of land and marine vegetation.
Coral reefs can only grow in the photic zone of the oceans because zooxanthellae algae use sunlight, CO2, calcium and/or magnesium to make limestone.
The calcification rate of Flinders Reef has increased along with atmospheric CO2 concentrations since 1700…
As the atmospheric CO2 concentration has grown since the 1700′s coral reef extension rates have also trended upwards. This is contrary to the theory that increased atmospheric CO2 should reduce the calcium carbonate saturation in the oceans, thus reducing reef calcification. It’s a similar enigma to the calcification rates of coccoliths and otoliths.

I didn't read all of it but I really liked the tone. I am far more afrade of global cooling than global worming. Keep on heating it up!!!!

Ocean Becoming More Acidic, Potentially Threatening Marine Life
ScienceDaily (Feb. 23, 2009) — A dramatic increase in carbon dioxide levels is making the world's ocean more acidic, which may adversely affect the survival of marine life and organisms that depend on them, such as humans. The article "Off Balance Ocean" is scheduled for the Feb. 23 issue of Chemical & Engineering News. Ocean Becoming More Acidic, Potentially Threatening Marine Life
Oh boy, has anyone considered the fact that CO2 comes out of the water during gas exchange? When waves break on the shores it exchanges CO2 for oxygen as well as it does along the many square miles of surface water. If the CO2 is getting in through the surface, then so is oxygen. These scientists, and I use that term loosely, are acting like CO2 gets into the water and never comes out.

It's an equilibrium process - it's constantly going in and out. These chemists are very aware of that (at a much deeper level than you). The more CO2 in the atmosphere, the more CO2 that is sequestered in the ocean. It's sequestered as carbonic acid, which then has it's own slew of equilibrium processes in the ocean. If you work out, despite what workingclasshero claims, the amount of carbonate ([CO3]2-) decreases as more CO2 is dissolved into the ocean (and the pH drops).

The pH of seawater worldwide is dropping (acidifying) as oceans absorb ever more carbon dioxide from the atmosphere. Experiments show that the struggle by copepods, snails, sea urchins and brittlestars to balance the changing pH inside their bodies impairs their ability to reproduce and grow. Many species are unlikely to genetically adapt to ocean acidification, because the change is occurring too quickly. As species wither, the marine food chain could be disrupted; human action is needed to curtail further acidification. How Acidification Threatens Oceans from the Inside Out: Scientific American
Unfortunately the only sources that some posters rely on are those by shills and articles bought and paid for by the environmental culprits.

PH levels won't drop to dangerous levels. that is just pure BS. There are other factors that effect PH levels than just CO2. The Carbonates and other buffers in the water keep PH at stable levels. Those carbonates are in much more supply than CO2. The entire ocean floor, coral reefs and all the limestone in the oceans are all carbonates and buffers. This is plain ole fear mongering.
