This is a concern which is also raised in the article by Monroe (2009), where the results of an experiment designed to confirm this effect were as expected. Accordingly, "[Victoria] Fabry, a biological oceanographer and visiting researcher at Scripps Institution of Oceanography at UC San Diego, studies the effects of ocean acidification on the mollusks known as pteropods. In one experiment, only 48 hours of exposure to slightly corrosive seawater caused normally smooth shells to become frayed at the edges on their way to eventual dissolution, severely diminishing their owners' chances of survival." (Monroe, 1)
This demonstrates that the increased acidification of the ocean's waters is causing a direct reduction in certain shell-dependent species of invertebrate. The article published by ANI (2010) identifies several species which have already begun to show evidence of the negative repercussions of the increased acidification. ANI reports that "the increased acidity of the seawater itself can literally begin to eat away at the outer surfaces of shells of existing clams, snails and other calcified organisms, which could cause species to die outright or become vulnerable to new predators." (p. 1)
Where the former occurs, we can begin to see the manner in which the diminished presence of one species can cause a chain reaction disrupting entire ecosystems. According to Townend (2010), such species "are common ocean prey, and plankton are at the base of...
Ocean acidification could disrupt the entire marine ecosystem." (p. 1)
To the point, evidence further suggests that the process of acidification is poisoning not just invertebrates but simultaneously their host habitats. Pinet (2009) gives extensive attention to the fact that the coral reef habitats upon which so many species depend for sustenance and survival are being 'bleached' by the toxic levels of acidity in their surrounding water. (p. 573)
Hypothesis:
This preliminary research contributes to the following hypothesis, upon which further research is to be conducted: The disruption of invertebrate ecologies as a result of ocean acidification is having a direct impact on the marine life upon which human's rely as a major food source.

Pollutants Compound Threats to Coral Reefs and What That Means for the Ocean and Us Humans POLLUTANTS AND CORAL REEFS All over the world, the existence of coral reefs in the oceans face a lot of danger caused by pollutant compounds. A lot of consideration therefore needs to be put in place to access the effects caused by these pollutants on human beings and possible remedies on the impact of the
Global Environment Continue to Deteriorate? Given the planet's struggling economic and social conditions, the exploding population, the spreading plague of violence, the increasing depletion of natural resources (forests, etc.) and the urgent need for new energy resources, the ignorance towards conservation and sustainability, and the heating up of the planet, there is every reason to believe that the deterioration of the world's environment will indeed continue. That is not to
Yet, there have been transplant successes in sheltered embayments. One of the major conclusions that have been seen is that the cost of reef repair and coral transplantation is generally high but effectiveness is usually very low. Protection and conservation, rather than restoration of damaged reefs, is the preferred priority. However, there have been a number of successful mitigation efforts in Hawaii (Jokiel, ). Disorder is a natural structuring force
Marine Bioluminescence Bioluminescence can be discovered across an extensive selection of some of the key categories of organisms. This includes classifications such as bacteria and protists and also squid as well as ?she's, with numerous phyla amid them. In many of these organisms, luminescence is made by these organisms themselves and never by bacterial symbionts. A few organisms in this category that are not considered to be self-illuminescents are (1) terrestrial
SCUBA and the Environment: A Paradox The relationship between SCUBA diving and environmental and marine health is a strange, tenuous, and paradoxical one. On the one hand, diving activities and the ancillary effects of diving-related tourism have threatened and in many cases, outright killed coral reef systems (McVeigh, 2018). Popular diving sites have in many cases been irreversibly damaged. For example, busy sites are known to have “more broken corals, a
