I am writing this letter to urge you to support the research efforts on Karenia Brevis, or Red Tide. A natural phenomenon I am sure you are aware of. Karenia Brevis is an extremely invasive species that creates a state of turmoil for the Gulf of Mexico’s ecosystem. This harmful algal bloom is not only responsible for the destruction to marine species, but is harmful to human health. Red Tide is also responsible for the loss of millions of dollars in profit and revenue for coastal industries and towns. There are ongoing research experiments testing ways to control Red tide before it can cause its damage, but support and funding is desperately needed.
There are many factors that contribute to the growth and spread of this harmful algal blooms, or HABs. According to livescience.com, “low salinity levels, a high nutrient content and warmer than usual water temperatures “, directly contribute to the growth of Red Tide. Another event that can trigger a massive red tide bloom is dust from the Sahara desert settles onto the water during rain events,

Brevetoxin exposure affects all types of fish, this toxin causes corkscrew swimming patterns, pectoral fin paralysis, and curvature of the caudal fin. Basically, the fish die because their gills can no longer function properly. Red tide is responsible for the deaths of nearly 840 bottlenose dolphins since 1988. The dolphins were tested by researchers and all tested positive for brevetoxins either found in their lungs from inhale the toxins or in their digestive tracks from ingesting contaminated prey. (myfwc.com) Red tide blooms have also claimed the lives of 241 manatees, further threating an already endangered species (nytimes.com).Furthermore the decay caused by red tide causes hypoxia, an event that depletes the oxygen in water making it impossible for marine life to thrive in the infected

One famous quote from Barbara Jordan is “If you’re going to play a game properly, you’d better know every rule .” Barbara Jordan was an amazing woman. She was the first African American Texas state senator. Jordan was also a debater, a public speaker, a lawyer, and a politician. Barbara Jordan was a woman who always wanted things to be better for African Americans and for all United States citizens. “When Barbara Jordan speaks,” said Congressman William L.Clay, “people hear a voice so powerful so, awesome...that it cannot be ignored and will not be silenced.”
In the nineteenth century, the Florida manatee population started to decline in numbers due to settlers hunting them for their meat (Pittman 15). In addition, during that time some of the scientists started to notice a decline in manatee sightings in areas they were known to migrate. Since permits were being granted to kill Florida manatees for science, and poachers were hunting them for their meat, government officials and researchers were concerned for the manatee's future (Pittman 17). Currently, there are many factors the Florida manatee is facing that poses a threat to their existence. Unfortunately, the greatest threat to the Florida manatee in the twenty-first century is boating and the loss of their natural habitat (McAullife 18). In fact, many boaters who have businesses have protested that their businesses are more important than the clumsy animals. Currently, another public concern for the Florida manatee is the increase of toxic blooms that cause red tide. In addition, since records have been kept researchers have discovered that red tide has been playing a role in the decline of the Florida manatee as well (Raloff 56). Red tide is a form of many toxins that are consumed by the manatee when they feed on seagrasses causing lung
cut back on the problems in the Bay. Scientists have given an unthinkable amount of attention to the Bay of the past several years and researchers from countless numbers of agencies and institutions have dove deep into the issues and studying every nook and cranny to create answers to every politicians’ questions. The biggest concern with the Bay, and the most concentrated ...
Eutrophication is a concern in the Chesapeake Bay. Eutrophication is caused by excessive amounts of nutrients. Excessive nutrients in the bay have negative affects on the bay's ecosystem. The extra nutrients make the environment unbalanced. The extra nutrients cause a chain reaction that depletes oxygen and kills most of the organisms in that area. This is what is known as a dead zone.
The Chesapeake Bay plays host to an astonishing amount of plant and animal life, providing much of our fish intake for species that aren’t being overfished. For the species that are being overdrawn, the Chesapeake Bay Foundation is working to restore the populations, and it’s going well thus far. Another theme that is endangering the marine life populations as well as the health of the human population is the massive amount of polluti...
The Chesapeake Bay has faced an excessive amount of pollution over the past century. The water in the bay has become so highly polluted that It is capable of causing harm to humans coming in direct contact with the water. Although algae serves a vital role in the bay’s ecosystem, it also creates a problem that is causing a large amount of the problem.
As mentioned before, brevetoxins can cause human respiratory and digestive illness, and consumption of brevetoxin-contaminated fish and mollusks is associated with neurotoxic shellfish poisoning (NSP). According to the data, people in Sarasota, Florida visited the hospital emergency department for digestive illnesses during red tide outbreaks increased by 40% in 2001 relative to in 2002 when there was no red tide bloom (Hoagland, et al., 2014). In addition, multiple substantial effects of brevetoxin immunotonicity are postulated by scientists, such as the inhibition of cathepsin active sites, apoptosis, the release of inflammatory mediators, cell cycle, and oxidative stress. Several effects listed before can have profound problems on human health such as apoptosis, cell cycle and oxidative stress can lead to cancer. The experimental results suggest that the apoptosis postulation is based on the in vitro assay that DNA damage was observed in human lymphocytes treated with brevetoxins and several apoptotic gene expressions were altered in brevetoxin exposed Jurkat cells. The oxidative stress will result in the depletion of glutathione in U-937 human monocyte cell line treated with PbTx-2. Also, DNA strands breakage and chromosome aberrations were observed under oxidative stress (Fleming et al.,
A big change that has occurred in the oceans all over the world is the Coral Reefs are dying and are predicted to be dead by the end of the century due to the rising acidity of the oceans caused by many different threats to marine ecosystems. Coral reefs cover less than 0.2% of our oceans but they contain 25% of the world’s marine fish species according to Endangered: Biodiversity on the brink, 2010: pg.45). If this is the case that means by the time the end of the century comes around we will have lost close to 25% of the worlds marine ecosystems.
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
The coral reefs of the world need our help now. You do not have to be a marine biologist to have an effect on the reefs around the world. By simply conserving water, you can help limit the water runoff into the oceans. Limit the amount of emissions put off by vehicles by carpooling or taking a bus. Even though we may live thousands of miles away from a coral reef, we must use caution when adding chemicals to our lawns. Planting a tree not only reduces the amount of water runoff; it also lowers the earth’s temperature. Something as simple as spreading the word can have major
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
By the oceans being polluted not only are animals affected humans are too. What some people don't know is that they are killing of and disturbing offspring by polluting waters. "Ocean pollution results in smaller catches of fish all over the world, either by killing fish directly, preventing them from breeding, or causing birth abnormalities. Seabirds are unable to breed and whales are poisoned. Pollution also seems to be responsible for a new disease among seals. Without even swallowed, plastic can kill seabirds, turtles, and other creatures by trapping them. People drinking water from polluted seas can become sick. Deadly infectious diseases like cholera and typhoid can break out." There are many different types of sizes of plankton everywhere in our ocean waters.
