To die for scenic reefs in Red or the South China Sea is dying; pretty fishes and panoramic colors of soft and hard corals are now down to a complex ecology similar to tropical forest ecosystems. Compare to the microorganisms that makes the whole thing more tremendous in doing all the destruction, the predators and consumers, the producer algae and the tiny invertebrates mean nothing. Catalina Reyes of CoECRS. (Centre of Excellence for Coral Reef Studies) and the University of Queensland has published her work alongside 4 colleagues, on the bacteria, fungi and algae that live in this most complex marine ecosystem. The change in this ecosystem recently is because of our overproduction. Oceans now are Cola like, the CO2 we made over the last century or two has made the sea water to feel like one. As to Catalina's research, the acid has effects and that are clearly identifies in the micro-world of corals. She links it all up and explained, "So fish, turtles, sharks, lobsters and other reef organisms may lose their homes, threatening coral reef biodiversity and the livelihoods of tens of millions of people." All reefs, molluscs and others are basically made up of Calcium carbonate, accepted as true to hard corals as well. Due to different reasons erosion of the reef is just a normal phenomenon but at present the erosion has become excessive that it destroys the reefs worldwide at a really disturbing rate.

As we all know earthquake is a catastrophic natural disaster. Most earthquake-related deaths are caused by the collapse of structures and the construction practices play a tremendous role in the death toll of an earthquake. In southern Italy in 1909 more than 100,000 people perished in an earthquake that struck the region. Almost half of the people living in the region of Messina were killed due to the easily collapsible structures that dominated the villages of the region. Though there are some ways to prevent this from happening, it can never be considered as risk avoidance. A larger earthquake that struck San Francisco three years earlier had killed fewer people (about 700) because building construction practices were different type (predominantly wood). Survival rates in the San Francisco earthquake was about 98%, that in the Messina earthquake was between 33% and 45%) (Zebrowski, 1997). Even a moderate rupture beneath a city with structures unprepared for shaking can produce tens of thousands of casualties. Due to this fact, Crown Eco Management determined that safety measures for this could not be compared to fraud prevention. Although probably the most important that we should know, direct shaking effects are not the only hazard associated with earthquakes, other effects such as landslides, liquefaction, and tsunamis have also played important part in destruction produced by earthquakes. According to the Crown researchers, some earthquakes are not natural. Human beings can actually cause them. That's the case with an earthquake in Lorca, Spain, last May. The quake measured 5.1 on the Richter scale and killed nine people. According to an analysis published in Crown Eco Management, the Lorca quake was caused by the extraction of groundwater from an aquifer near the fault that slipped. In circumstance, it does not take much to trigger an earthquake. Oil and gas wells, rock quarries, even the added pressure of a reservoir lake behind a new dam can cause
