Another thing that effects the blue crab 's ecosystem is its environmental threats. To begin, one of the environmental threats that blue crabs face is pollution. In the text, it states, “Approximately 6.4 million tons of plastic and other debris enter the oceans each year. And every year., more than 1 million marine animals die from eating or getting caught in this debris,” (Dignan 13). This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem.
Pteropods are important sources of nutrition for many types of fish, whales and birds in polar and sub-polar regions. The effects on corals, already highly sensitive to their environment, are particularly concerning, since one part of all marine species depend on coral reefs for homes, nurseries, feeding grounds and spawning sites. This equates to nine million marine species, including four thousand species of fish. ocean forecasts the mass extinction of corals in both tropical and cold waters this century, if carbon emissions growth continues unchecked. How will ocean acidification affect
“Our globe is under new dramatic environmental pressure: our globe is warming, our ice caps melting, our glaciers receding, our coral is dying, our soils are eroding, our water tables falling, our fisheries are being depleted, our remaining rainforests shrinking. Something is very, very wrong with our eco-system” (Lamm) It may seem very overwhelming on where we should start to help our environment since it seems like such a big task. One small place that we can start is with helping our bleached coral which can help the whole state of our
Fourth period: January 1942-September 1942 This period was characterized by heavy sinking on the coast of United States. Japanese ships sank and the country incurred heavy losses. The submarine was responsible for those shipping losses. Major changes were made in the war whereby the battleships were no longer used. This was a result of the attack that happened in Japan in 1941.
Other surveys done from 1999-2000 revealed the almost total decline in the Lettuce coral and large death in other species (R.B. Aronson, 2015). At the start of the late 1980’s, white band disease almost destroyed the St. aghorn corals, Aeropora cervicornis from reefs in the central shelf lagoon of Belize. The lettuce Coral, Agaricua tenuifolia replaced Aeropora cervicornis in the early 1990’s, at the same time high water temperature in 1998 caused severe bleaching and death of the Agaricua tenuifolia. This left a univocal mark in the fossil records of these uncemented lagoon reefs.
Populations of these animals either increase dramatically or decrease dramatically, e.g. the crabs that would eat these fish in 1992 had their populations increase suddenly, due to the loss of their main predator, whereas shark numbers and other predators of the fish would decrease due to lack of food. As a result, these animals will hunt other fish and decrease the population and etc, resulting in a mass increase and decrease of populations in the ocean. Some major issues surrounding overfishing are environmental sustainability, unemployment and economic loss. The questions that the issue of overfishing poses are ‘do the benefits of overfishing outweigh the disadvantages?’ or ‘how can people change the method of catch in order to provide enough food for people whilst preserving populations?’ National/Local Perspective in Hong
In 2010, there was a catastrophe of Oil Spill in Mexico and it bigly affected individuals ' lives and species in the ocean. A seaward British BP Oil rig broke and spilled around 30,000, 40,000, and 60,000 barrels a day for more than 2 months. This was a catastrophe for nature and for a huge number of individuals. The occurrence that happened on April, 2010 has put a major effect on individuals ' lives. The affliction of Oil Spill in Gulf of Mexico was in the middle of life and passing on the grounds that the conductor did not check for wellbeing first.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health. Overfishing is also closely tied to by catch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and
Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world. Most of the waste produced on land is either intentionally or unconsciously discharged into the oceans. Marine pollution and aquatic debris can utterly destroy the oceans causing extinction of the marine creatures. Innovative techniques should be implemented in the law to prevent the marine environment from any further damage. In order to improve the marine environment, the government and the Environment Public Authority of Kuwait should take immediate actions that can influence the society and help in minimizing aquatic debris and pollution.
As the rate of plastic production exceeds the rate we get rid of it; it will soon overtake our oceans. In 2010 alone, it was estimated that over 300 million tons of new plastics were produced around the world, (QTD. By UC Davis USA on YouTube). Many oceans from North America and Japan are being polluted by our carelessness and are causing our marine life to suffer. Marine mammals such as seals are being found entangled in plastic fishnets and several drown.
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.
It is believed that this increase in nutrients is connected to the increase in crown of thorns starfish population, which poses another threat to the reef by impacting coral cover (Amelia S. Wenger, 2015). Coral diversity, calcification, coral cover and coral development are all being impacted by chemicals reaching the reef (Amelia S. Wenger, 2015). If the amount of chemicals reaching the reef continues to increase, the reef will continue to diminish, coral species will become extinct and reef fish will lose their habitat, forcing them to relocate or
Climate change will affect communities in the north by destroying the best way to transport things. Finally, the sea level rise and flooding is a big problem people-wise. Flooding causes millions in damage that sometimes cannot be reversed. Flooding is encouraged by climate change because of the increase in moisture trapped in the air, and rain happening earlier in the year and falling on still frozen ground. Houses being destroyed by increased water also leave people homeless and cost a lot to fix.
The Great Barrier Reef has and will continue to face countless threats in its lifetime. The reef has survived through millions of disastrous events through the years. The Crown of Thorns Starfish (COTS) is a major threat to the coral reefs which helps destroy the Great Barrier Reef. This threat may be no bigger than a dinner plate, but it is one of the biggest threats to the Great Barrier Reef. Kate Osborne and researchers discovered that Crown of Thorns Starfish were responsible for 36.7% of coral damage, 33.8% caused by storms, 6.5% by disease, 5.6% created by bleaching and 17.4% unknown or multiple causes of the damage to the Great Barrier Reef, as shown in Appendix 1 (The Conversation.
This includes 86% sea turtles species and 44% of all sea birds species. Plastic pollution has impacted them with fatalities such as ingestion, starvation, suffocation and infections. Water bottle company 's shouldn 't take the blame for the pollution. I think that the people who litter and throw away their rubbish in the oceans are responsible for it. People who litter are harming the ocean and making it dirty that has cause a lot of animals to die.
