Blue Crab Threats

The Times Union Editorial Board warns Americans about the dangers of their actions in their article “We Must Step Up Efforts to Save Endangered Animals.” They adopt a frantic tone in order to make the reader worry about what they’re doing. The Editorial Board uses pathos, logos, and ethos to convince the U.S. population to consider their actions.

For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

Many different theories have been suggested to explain why the East Coast Fishery collapsed. A few examples include overfishing, destructive fishing practices, and changes in natural conditions. Primarily, overfishing plays a huge role in the collapse of the East Coast Fishery. The amount of catch allowed by the federal government was extensively high. Scientists may have overestimated the number of fish reaching adulthood each year, due to this more fish were caught then reached maturity. In addition, the collapse of the East Coast Fishery also revolves around the theory of destructive fishing practice. Many fishing practices can be extensively proficient at harvesting fish, but they often accidently catch non- target species, these species (also known as bycatch) are usually thrown/tossed away.

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.

This article presents the impact of climate change in the Chesapeake Bay. Scientists predict climate change will increase the water temperatures, CO2 levels, and stream-channels which will affect the Chesapeake 's physical, chemical, and biological processes. Greater CO2 levels will increase the water temperatures and the precipitation amount and precipitation intensity. Excess precipitation will create stream-channels to the bay, and increase the fluxes of NPS sediment, phosphorus pollution, and nitrogen. Stream-channels deliver sediments and nutrients to the bay, driven to non-point sources. Nutrient-loading will increase the dissolved oxygen, which high levels will harm aquatic life and affect the water quality. Fish and other species will

The Louisiana coast is a natural, economic, and cultural tourism resource. It features an area rich in ecological abundance that supports activities such as commercial and recreational fishing, habitat for a number of waterfowl, migratory birds, reptiles and amphibians. In addition, it has five of the top 12 ports (per cargo volume) in the United States. It is a major supplier of US natural gas and oil power and home to more than 2 million people - nearly half of the state's population.

Cool, calm crashing waves along the coast of the Great Lakes is an timeless picture many generations have enjoyed. The Great Lakes have the same beautiful views as it does in years past.

In the article, Sufficiency of Horseshoe Crab Eggs for Red Knots during Spring Migration Stopover in Delaware Bay USA, it is argued that the survival of Red Knots is reliant on the nutrition of horseshoe crab eggs. However, it appears that the overharvesting of the horseshoe crab eggs dictate the Red Knot population during their spring stopover. The management of horseshoe crab eggs will ensure the availability to Red Knots, which are dependent on them for endurance during their migratory flight to the Artic.

Abstract – The study to prove that ecological succession occurred at Conrad’s beach took place at Conrad’s beach in Nova Scotia. Species richness, height and amount of organic material was sampled by using a 1m x 1m quadrat. As predicted the abundance and size of the organisms were larger further as the groups got further from the sand dunes.

As we progress through the course, a complex yet clearer picture is forming regarding how impacts as a result of changes to environmental systems extend well beyond impacts to the wildlife that inhabit those systems. It has become increasingly apparent that environmental changes influence social and economic dynamics as well. The visibility of environmental issues affecting consumers and wildlife alike is very present when we examine estuaries, also know as bays, sounds, or lagoons. Estuaries are mixtures of freshwater and seawater and are created within the indentations found along coastlines. All along the coast of California, where I reside, there are several bays to be found. With many of our major cities built in coastal zones and nearly

1. It is a scientific fact that biodiversity is greatest near coral reefs and estuaries. But because of human influence coral reefs around the world are dying. Human coastal development, pollution, ocean warming, and ocean acidification are all things that threaten them. The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing. All in which are man made influences that affect the ocean greatly. It is predicted that by the year 2050 90% of the coral reefs on earth will be dead or threatened. Not only that but soil erosion, algae growth from fertilizer runoff, increased UV exposure, and damage from fishing and diving are just adding to the problem. However, the

Overfishing means to deplete or exhaust a stock of fish or shellfish by excessive fishing. This may not seem like a topic that is ever worth argueing over, or worth making laws for, but little do people know that the consequences of overfishing will soon affect the entire world. This will not only affect ocean life, it will also affect humans, as well as all other living organisms lives as well. There are already several overfishing laws existing, but they are easily avoidable and is done so with so many large fishing companies. These laws need to be taken more seriously and need to be highly enforced. if t some changes are not made soon then it could destroy ecosystems and leave the ocean in ruins. There are several ways to prevent

According to world wildlife organisation, overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results may not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life.

Another issue is shipping accidents and oil spills. Mostly merchant vessels, commercial ships, use the Great Barrier Reef shipping route. According to Australian Maritime Safety Authority (2002), from 1985 to 2001, 11 collisions and 20 groundings occurred along the reef shipping route. These shipwrecks caused 282 oil spills between 1987-2002. In addition, Zubrzycki’s report (2013), Australia approves on of the world’s largest coal which will cause severe damage to the reef. Environmentalists state that the reef will be placed on in-danger list of Unesco’s World Heritage Centre. (Great Barrier Reef Marine Park Authority (2006). “Principal water quality influences on Great Barrier Reef

Holland America Line (HAL) has grown into a sustainability leader in the global cruise line industry. HAL, headquartered in Seattle, Washington, was founded as a shipping and passenger line in 1871and in 1895 offered its first vacation cruises. Since the early stages HAL has always sought to become a leader in sustainability, in 1989 it became a wholly owned subsidiary of the Carnival Corporation. This was a huge play for HAL because, Carnival Corporation was the largest company in the cruise line industry, dominating 52% of the market. Since joining Carnival, HAL has been one recognized as a leader in the cruise industry in its environmental sustainability. HAL has been a recipient of many prestigious awards for their efforts in sustainability.
