The influence of global warming on sea water temperatures have caused the "Dead Zone" in the ocean. Very broad area of water that is devoid of life due to loss of oxygen and release of hydrogen sulfide gas (H2S). According to reports from the UN, there are now more than 200 dead zones. One zone appeared in the Pacific Ocean off the coast of Oregon, USA in the last year and its size has increased 4 fold. There is almost no oxygen in this area. If the oxygen is gone, the new bacteria will take over and produce hydrogen sulfide gas that is deadly to marine life and the earth.
The fish Sharks Endangered Due to Climate Change.
The study recently published in the journal Conservation Biology that populations of many shark species are diminishing quickly make the scientists are concerned about the impact on marine ecosystems as a whole. Conservation groups call for global measures to protect sharks, even some types almost disappeared altogether. (Http://news.bbc.co.uk/2/hi/science/nature/7446112.stm)
Based on the above information we can know that so many complex issues that occur around us due to global warming which most affects the Earth's surface temperature rise. I strongly disagree with the impacts that occur as a dead zone in the waters of the sea and I am also very concerned with the future impacts that may occur. Dead zone is the zone where the organism is difficult to survive in general due to the lack of dissolved oxygen content and the waters contained high content of H2S gas contained therein. Of zonai die is not very good for marine organisms such as fish and no exception is also on the existing natural food such as plankton at sea. Plankton, phytoplankton in this very need sunlight for fotosintesisnya process and they also need oxygen for respiration at night. Similarly, the zooplankton. They are very dependent on the oxygen content dissolved in the water to breathe. If this dead zone continues to grow in the ocean, then it will definitely threaten the lives of marine organisms such as fish and plankton is no exception. Sure it can cause many marine organisms die when trapped in this dead zone. Another thing to keep in mind also, the oxygen content in water will decrease with increasing temperature in the waters. In other words the effects of global warming due to these dissolved oxygen content in the waters would be decreased and this resulted in competition for marine organisms to obtain sufficient oxygen for life. That's what today we often hear in the presence of 'Die Plankton' in the waters because of plankton are not getting enough oxygen to death.
Information both about the sharks that are currently being increasingly shifted and was on the verge of extinction. I am very worried if a shark or even the less populated punak because if it happens makadapat ekositem disrupt the overall balance of marine ecosystems in particular. Sharks are the top consumers in the food chain in a sea ekositem. If the extinct shark will certainly disrupt the stability of the food chain in ecosystems. For example:
Plankton - small fish - the fish are - big fish - sharks
If the shark does not exist there will be a population explosion in the big fish. Because of the high population of big fish will certainly spend a fish population is so that the chain becomes disconnected. This is likely to impact on the plankton that should be consumed by small fish. Resulting in population explosions of plankton in the waters. Because of the high population of plankton is usually dissolved oxygen content in water is not enough to sustain life, causing mass death of plankton plankton. So that the equilibrium ekositem very important and we are thirsty guard.
So many things happen as a result of current global warming from rising temperatures, rising sea levels, the number of emerging diseases, prolonged drought and others. It is very difficult to avoid. So let kuta together - just reduce the impact of global warming with mepelajari why, how mangantisipasinya, joined in support of environmental organizations and other activities - ilain. And in essence start from the smallest that is from our own natural self. Care for the environment starts with yourself.Share this:
