The oil spill took a huge tool on alaskas fishing industry, forcing many Alaskan citizens which depended on the fish for their income to be pressured into some kind of a depression. In particular, the oil spill had affected trade of Alaska, particularly the industry of fishing in the region. According to surverys taken fishermen of Alaska have lost over three quarters of a billion. This is due to the oil spill because it ruined the Alaskan salmon in the region. The total damage done to the ecosystem and fish lost weighed in around six hundred million dollars (Fernando,
Still to this day, the Gulf War oil spill remains the worst disaster of its kind. This spill resulted in the death of over 10 thousand sea birds and threatened sea turtles and marine mammals in the surrounding areas (Baumann, 2001). The second largest oil spill was the Deepwater Horizon oil spill, also known as the Gulf of Mexico, or BP Oil Spill that occurred more recently in 2010. This oil spill was caused by a surge of natural gases resulting in the explosion of the Deepwater Horizon rig. The explosion occurred while workers were at the rig attempting to activate the blow-out preventer, this BOP malfunctioned and the rig exploded killing 11 workers and injuring 17.
The industrial production of steel, cement, and brick are other major sources that account for 49% of Nitrogen Oxide in that region. According to Los Angeles Times, (Air pollution takes years 1) “People die 5.5 years earlier in northern China than in the south, and heavy air pollution is almost entirely to blame.” Not only is the air pollution awful, but the pollution levels in water are also unbearable. Factories around the world make their products, releasing their smog into the air and the nearby lakes, ponds, and bodies of water. In return thousands of aquatic wildlife are becoming endangered species daily. Chris Woodford (Water Pollution: an Introduction 1) explains “Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways.” Radioactive wastes and oil spills affect the wildlife living in these areas in great ways.
Since the shark fins are second most valuable illegal trade, after drugs , the hunting is done around the world and the fins are sent to China and other countries where the Asian traditions exist. Tens of millions of sharks are every year facing a slow death because of finning. The shark is caught and they remove the fins and then throw it back into the ocean – still alive. The death is often in the end caused by starvation, being eaten by other fish or drowning since they can no longer be in constant movement and therefor not extract oxygen from the water. This long tradition has now led to some shark populations being declined to up to 98% in the last fifteen
Coastal development: The growth of coastal cities and towns generates a range of threats to nearby coral reefs. Degradation of coral reefs — can result in lost tourism income in countries that are dependent on reef-based tourism and also can reduce fish populations Coral Reef Degradation is caused by natural and man-made events. ... Water pollution comes in a variety of different sources, oil, gas, and pesticide, They poison coral and marine life. Coastal construction — can cause chronic sedimentation, sewage effluent, industrial discharge, and changes in water flow and run off, which can directly affects the coral increasing rated and metabolic activities as well as it directly kills all of the corals Removal of reefs — can result
Eversince the invasion of Zebra mussels in 1988 the ecosystem of The Great Lakes suffered negative impacts from decrease of plankton to spending big numbers every year to try to remove them from the ecosystem. But little do people know they also help brought Lake erie (one of the 5 great lakes) back to life, during the 1970s Lake Erie was declared dead since massive amounts of pollution were dumped into the Lake from agriculture industry. The pollution caused the Lake to have less oxygen which caused some parts of the lakes to be a dead zone. Overall this can be concluded to have negative impact to the ecosystem of the Great Lakes, but there are some positive impacts too. The primary objective should be to remove the Zebra mussels from the great lakes even though the had positive impacts, the zebra mussels don’t belong in this ecosystem.
Manatees are mammals known to live for about 50-60 years, but unfortunately, they were short-lived and died after ingesting/inhaling toxins, which later affected their organs. In the cases of the deceased manatees, it was found that severe renal, hepatic, cerebral, pulmonary, and nasopharyngeal congestion was found. Through the use of *immunohistochemical staining, traces of brevetoxins were found in the secondary lymphoid tissues, lung, and liver. Toxic algae in the water is recognized for moving through the air like a powder, which puts manatees at risk due to inhalation. Also, toxic algae may be found in the plants that they eat, affecting their gastrointestinal system.
Sediment erosion can affect coral reefs and oyster beds causing even more deaths. They also cause erosion on land, destroying most animal’s habitats and even leaving some islands underwater. Forests become destroyed and force animals to relocate, if they were able to survive the hurricane.
About 4.37 million chickens died following the earthquake and tsunami, causing a short in the supply of feed for overseas suppliers. An estimated 90% of fishing boats in Miyagi, Iwate, and Fukushima were unusable by the tsunami; at least 440 fishermen were killed or missing. The total damage to Japan's fishing industry was estimated at ¥1.26 trillion. It is said that the estimated economic loss may be around 171 billion–$183 billion just in the region hit by the quake and tsunami. Because of the Tohoku Earthquake and tsunami caused many lands, resources (food, human, products, machines) and enterprise in ruins, with these damaged done, Japan’s economic problems will be hard to
Also, the ocean filters the air we breathe, and like said before, supplies 80% of the oxygen we breathe. Pollution causes the ocean not to function properly and oxygen levels can and will diminish. The ocean is also home to medicines that treat heart disease, cancer, and more. The plants or animals that give us these medicines are endangered as long as marine pollution exists. The remedies can be lost causing more people to die because of the lost medicines.
Some marine species that are affected by bycatching are juvenile fish, bottom feeding organisms, sharks, whales, sea turtles, and birds. Losing ecological stabilization and unity will inevitably lead to the collapse of the ocean’s system. Not only does overfishing lead to environmental impacts, but also social and economic impacts. An example of this was the collapse of the Atlantic cod fishery in the 1990s. As a result, thousands of individuals left the fishery hoping to work in other areas.
Red Tide: How it affects Marine Life Red tide in Florida is a reoccurring problem that threatens marine life every year. Red tide in Florida waterways has a negative impact on marine life because it produces toxins that are harmful to marine species. It lessens the amount of oxygen in the water which ultimately leads to the migration and death of many different marine animals. Millions of dollars are poured into red tide research and prevention every year to help predict when and where a red tide is going to form. All the while, millions of dollars are being lost due to a drop in tourism and bans on fishing as red tide wreaks havoc on businesses and marine life.
Finally, changes in environmental conditions are also responsible for the collapse of the East Coast Fishery. Water temperatures have dropped and ocean salinity levels have changed, causing fish to change their migratory routes, and avoid areas that are changing. People have suggested that the increase in the seal population has reduced the amount of fish because greater quantities of seals eat greater quantities of fish. In conclusion, a number of theories such as, overfishing, destructive fishing practices, and changes in natural conditions explain why the East Coast Fishery has
Another natural cause is oceans and hurricanes. Both the ocean waves and hurricanes accelerate erosion, which is a main cause to the marshes disappearing. Something New Yorkers should realize is that "80% of oil and natural gases produced in the U.S. travels through our marshes" as according to page 12. America 's economy could go so wrong if the marshes the oil processes through suddenly disappears. Also, a huge percentage of marine life loves in Louisiana 's marshes.
The clams also clog water intake systems in private boats and homes, costing owners hundreds of dollars to fix. As a result, the clams did negatively impact tourism, property values, the environment, and the general economy of the town of Lake George. Not only did the Asian clam result in high intrinsic costs (i.e. removal, treatment, eradication, etc. ), but it also resulted in extremely high extrinsic costs on the town as well (i.e.
