Therefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
A change in the water 's temperature or chemical makeup can be deadly for polyps. Experts say that putting a stop to things that are harming coral reefs is a must. But they are also looking into ways to regrow them. Recently, scientists started raising coral polyps. They plan to put these polyps on struggling coral reefs.
For this reason, pollution and other environmental issues disproportionately impact oppressed groups. When faced with this problem, the people managing the Salton Sea crisis should consider implementing the system suggested by Wenz. The system is intended to prevent rich people (and companies) from being able to avoid exposure to harmful environments as well as lessen their involvement in decisions regarding overall pollution. The system itself involves communities earning equal pollution points that cannot be bought and sold on the market. In theory, the system would solve problems involving hazardous waste and companies would no longer be able to export pollution to poor
Ocean acidification leads to a reduction in the amount of carbonate ions in the water. Many marine animals essential carbonate ions for the calcium carbonate essential to form skeletons and shells. This will disturb their development and ability to reproduce – ultimately threatening their populations.. Falling numbers of less well-known species, like pteropods – tiny swimming snails – have important effects further up the food chain. Pteropods are important sources of nutrition for many types of fish, whales and birds in polar and sub-polar regions.
This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold. This allows overfishing to be a problem. Not to mention, another environmental threat that this fascinating animal, the blue crab, faces is climate change. Corresponding with the text, “Climate change is another major threat to life in the oceans. Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems,” (Digan 14).
Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely. Thus it is much better to prevent coral bleaching than to accomplish its recovery which may take many
Nassau, the capital of the Bahamas struggles a lot with plastic pollution because its main income and food source is fishing. Plastic pollution hinders the amount of fish they gather and therefore slows down the rate of their income. Nassau is already a LIC and therefore plastic pollution causes famine there. They have already started to think about banning plastic bags. And if the plastic pollution rises then there will be losses of $8.5 million in tourist income annually for the country because of the pollution on the beach this happens in other countries as well.
As noted earlier, tourism is one of the biggest business in Florida and the US Virgin islands, and with most of its tourist attraction destroyed, it leaves the state and territories still shaky about the future of their economy. Hurricane Irma have not only impacted the economy but more so the residents who are still trying to come to grip being a survivor of this catastrophic
Six of seven species of sea turtles (Chelonioidea) are listed as either vulnerable or endangered by the IUCN Red List of Threatened Species. The largest contributors to the decline seen in sea turtle populations are people, this being due to human activities such as fishing, tourism, shipping, industrial production, and coastal development, which have been scientifically proven to impact all seven species of sea turtles. Plastic pollution found in and around the ocean, light pollution along coastlines, and fishing are three of the main ways in which human activity impacts sea turtle populations. Sea turtles, also known as marine turtles, spend most of their life in the ocean, but they are found on land during their terrestrial birth process that involves laying their eggs in the sand; the vulnerable
The Cultural Effects of Coral Bleaching Located in warm, shallow waters, one species is near it’s extinction. Scientific studies has anticipated this for years, but many people do not understand the _damage this obsolescence would have on the environment. An essential animal in the ocean, coral, is, “home to 25% of all marine fish species,” according to The Reef Resilience Network, which specializes in helping save coral. Corals have very special tolerances to things like temperatures, salinity levels, and pollution, which causes coral stress, or bleaching. When bleaching occurs because of the unsuitable conditions, the corals expel the algae living in them, turns white, and dies, When corals die, thousands of sea creatures living around reefs
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
In addition, because nesting females generally return to their natal beaches and there is a low gene flow between nesting assemblages, these populations that are genetically distinct are at risk for extirpation (Ehrhart et al. 2003). Additionally, the potential for loggerheads to choose suitable nest sites is limited by human activity. Sea turtles will be less likely to nest on beaches that have high human recreation or that have been altered by humans. Beaches that are near human development pose a threat to sea turtles, not just by human presence, but because artificial lights prevent hatchlings from being able to orient themselves toward the ocean (Lindsay 2003).
However, it 's not only just because of man-made reasons. The coastal marshes disappearing can also be affected by natural causes. Sediment is being deposited into a river delta increasing the weight, which causes the entire area to sink (p. 11). Depositing may sound like a positive cause, but however if the course of the sediment changes then no new sediment will continue to be deposited. Another natural cause is oceans and hurricanes.
As humans expand they are producing more waste and need a place for it to go. In some countries, people just pump the waste into the water, as a result it is harming the manatees. The waste that humans are pumping into the ocean is causing toxic algae which the manatee eats and it makes the sick or could kill them. The waste from humans hurts the manatee also by
This research is helpful because it will allow business owners and tourists know when a red tide will occur and when to stay away from waterways. Unfortunately, there is not much that can be done about the marine life until they are actually affected by it. The United States is working on creating a building to focus on the prediction of red tides: Its goal is to improve existing models to explain more accurately and then predict the complex progression of a red-tide bloom. Successful forecasts could, for instance, allow fishermen to scoop up shellfish before a bloom takes hold, warn businesses to brace for a drop in beach tourism or alert managers to which environmentally sensitive areas they should be monitoring most closely (Schrope 24). This 1.25 million dollar center for red tide prediction will hopefully be able to target a red tide bloom before it actually occurs, but for now the most that can be done is to monitor where the bloom will move based on wind and water currents.
