They are a colorful ecosystem that plays an important role in the marine world and the human world as well. They are home to countless plants and animals‚ a source of food‚ medicines and one of the unique wonders of our world. While they might bring the image of life near a tropical paradise‚ there is much more to the coral reef than

Coral reefs are known to protect other sea life such as fish and attract tourists. As the ocean water temperature increases‚ corals are experiencing bleaching by ejecting algae‚ which is what gives them the various colors they are known for (Baird). The death of these precious coral reefs are jeopardizing fishing of those species that live off of coral. Coral reefs also create a “roadblock” in the ocean and without them there for protection

a piece of expository writing about coral reefs. I taught it fitting to write on coral reefs because they are so important and are getting destroyed every day. Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Living coral reefs are the foundation for many marine species

I. Attention Getter Coral reefs are the most diverse of all marine ecosystems. They teem with life‚ with perhaps one quarter of all ocean species depending on reefs for food and shelter. II. Credibility Statement Coral reefs are also very important to people. The value of coral reefs has been estimated at 30 billion U.S. dollars and perhaps as much as 172 billion U.S. dollars each year‚ providing food‚ protection of shorelines‚ jobs based on tourism‚ and even medicines (Knowlton‚ 2015).

The raw data provided by Riegl and Purkis’s study is what will make others wary of what is happening to coral reefs and furthermore encourage them to gain a deeper understanding of why we need these marine dwellings and providers. The reader of their study will find himself or herself internally pondering: “If we don’t have these coral reefs‚ how will humankind be impacted?” The data obtained from Riegl and Purkis in this study also help us to pinpoint what our best option

today are 30 percent more acidic than they were at the time of the Industrial Revolution. This interferes with the way that corals produce calcium carbonate‚ and it becomes difficult to build reefs. Oil spills are a major issue‚ and in recent accidents; ships hit coral reefs off India and spilt oil‚ causing reef damage. Surface currents are more rapid than the currents of the deep sea‚ limiting the ability of the deeper plumes (oil) to spread widely; oil and chemicals will diffuse as they migrate

Biological Theories “Biological theories of crime focus on the physiological‚ biochemical‚ neurological‚ and genetic factors that influence criminal behavior. However‚ such theories also stress the complex link between a person ’s biology and the broad span of social or environmental factors that sociological theories examine” (Denno‚ 2009). Biological factors that contribute to crime are something neurological or chemical related‚ which is not to be confused with a genetic factor that is inherited
