If you live near a coastal area, then you may have heard about red tides from time to time.
Although there are many negative effects caused by a red tide, there is a unique positive side effect.
We are glad you've been thinking about the ecosystem and the wildlife affected by a red tide, Wonder Friend Nike. It is a tide that has a lot of blood in it, warning the people that a heard of man-eating sharks that can run on land are coming.
I love the water, but it was so sad to see all of the fish that had died and had been washed up on shore.
Thanks for letting us know you thought today's Wonder was cool and that you like the Valentine's Day background, Paige! Thanks for letting us know what you thought about the video for this Wonder of the Day®, Kendall!
According to the Fish and Wildlife Research Institute, a bloom of Karenia brevis was spotted along the shorelines of Tampa.The Tampa branch of the National Weather Service issued a warning Tuesday saying that several residents from Sarasota to Charlotte complained of breathing issues resulting from the bloom.

Before you peruse the information on some of the worlds best beaches you need to be aware of one phenomenon  that occasionally occurs in the seas around Florida called Red Tide. Red tides are caused by an explosive growth and accumulation of certain microscopic algae, predominantly dinoflagellates, in coastal waters. It frequently causes fish to die and wash up on the beach, and causes humans to experience respiratory irritation and discomfort. There is a toxin in the air, released by the red tide algae, that causes mild respiratory irritation, or worse if you are particularly sensitive. We have experienced Red Tide and at times it was very unpleasant however It is important to know that many people still enjoy the beaches during red tides. Most people can still swim in Red Tides However, in some people, red tide can cause skin irritation and burning eyes. It is fine to eat fish, crabs and shrimp during a red tide because the toxin is not absorbed in the edible tissues of these animals. Seafood purchased in local restaurants and grocery stores is safe to eat as all commercial seafood must be harvested from red tide free waters.
There have been several significant developments over the past few decades in the Gulf of Mexico (GOM) which now require special and immediate attention. Some have since advanced the notion that global oil spill response has been forever changed for the better, because of how profoundly BP mismanaged the spill for all to see. The entire world watched in horror as millions of gallons of the dispersant Corexit were used to ‘disappear’ the gushing oil in the Macondo Prospect throughout 2010 and beyond. The single revelation about the ramped up toxicity of Corexit-treated oil served to awaken many stakeholders about the safety of dispersant use in our coastal waters.
It was through a confluence of many disparate circumstances during the gushing, “ginormous”  oil volcano which brought to light the following critical observations about the overall status of the Gulf of Mexico. What are the major factors contributing to the unrelenting degradation of the Gulf of Mexico?
We need to look no further than the mouth of mighty Mississippi River to assess some of the most obvious causes of the relentless destruction of the GOM. This mighty river and it’s many tributaries carry a tremendous chemical burden in the form of industrial waste, as well as rain runoff laden with every chemical imaginable from suburbia and cityscapes alike. When you add the untold volumes of leaked oil and gas into the mix in the undersea Mississippi Canyon by way of manmade oil spills, natural leaks and seeps, drilling mud and other highly toxic chemicals used by the Oil & Gas Industry, methane burps, undersea mud volcanoes, and the increasing vaporization of methane hydrates, an alarming picture starts to take shape. Just as each human body possesses its own very unique environmental profile, so, too, does the Gulf of Mexico. The components of drilling mud are much less about mud, and more about other highly corrosive and toxic chemicals which are necessary to do a very difficult job. A close reading of this material reveals an extraordinary number of highly toxic pollutants which can eventually find there way into the water columns, the wetlands, the estuaries, and onto the beaches, etc. The sheer number of oil wells drilled throughout the GOM since the early 1930s is quite staggering. The BP Gulf Oil Spill demonstrated how a blown well can present a predicament that simply cannot be fixed (See preceding diagram).
The preceding discussion provides only a glimpse into some of the various co-factors which are responsible for contributing considerable amounts of pollution to the total toxic load borne by the Gulf of Mexico every day … of every week … of every year … over many decades. Event the Atlantic Seaboard is being opened to oil and gas exploration so powerful is the Oil & Gas Industry lobby in DC.
In virtually every article that has been published in the mainstream media over the past decade about the many deaths and serious illnesses that have been directly linked to the GOM, there is often a qualification about the individual who died or who became seriously ill or diseased. While it’s true that a fisherman who is immuno-compromised is more susceptible to serious infection should he enter the waters with open wounds, it is also true that any individual with open wounds or sores can be easily infected by Vibrio. What is being proposed here is that the more resonance that occurs between the human body and the GOM body of water during swimming, fishing, snorkeling, and boating activities, the greater the likelihood of adverse health consequences.
The spate of articles over the past few years regarding the flesh-eating bacteria incidents coming out of the GOM clearly indicate an evolving predicament which no one in government — federal, state, or local — or from industry, want to address in any meaningful way. Likewise, the many businesses and industries which rely on the GOM are no longer inclined to trumpet serious health alerts, such as the rising incidence of Vibrio infections. The same is true for the homeowners and commercial property developers, particularly the wealthy, whose mansions dot the coastline from the Florida Keys to the southeastern coastline of Texas. Vibrio is only one of numerous pathogenic micro-organisms which will proliferate in such a conducive environment as the GOM.
Red tide has been visiting the Gulf Coast for many years now, except that the outbreaks have become increasingly more severe and affecting larger areas. Here’s what the NOAA (National Oceanic and Atmospheric Administration) has to say about Red tide, also known as harmful algal blooms, or HABs.
What NOAA will not tell you about Red tide is that there are circumstances beyond certain environmental conditions which encourage this highly toxic algae to bloom. Likewise, when the GOM’s normal balance of both eugenic and pathogenic micro-organisms is thrown off, a similar set of circumstances can result.

Of course, this is exactly where much of the swimming, water sports, fishing and other GOM activities take place. Nothing demonstrates this concept better than the existence of multiple dead zones throughout the GOM. Likewise, the GOM has its own environmental profile which affects all who live near it, work in or on it, as well as eat the catch from its waters.
Although the first responsibility of government is to safeguard and protect the citizenry, this rarely happens in contemporary society.
In closing, it is indisputable that the Gulf of Mexico will continue to absorb a toxic burden well beyond its capacity to effectively process. In this section we will be looking at the indirect effects of the meat industry on human health.
Although they sound pretty, red tides usually bring dire warnings with them.Red tide is a common but deceptive term for a natural phenomenon that occurs regularly along most coastal areas.
In some areas, phytoplankton that are bioluminescent put on a special light show after dark.As the waves toss them about, phytoplankton emit flashes of light.
We think it's SUPER that you spotted a red tide and have been WONDERing about its impact on humans. This one girl, their graveyard was on another side of the water so they had to wait for the tide to go down.
While it is always present in the Gulf in negligible amounts, large blooms turn the sea a reddish brown color.
It can kill fish and other aquatic animals, and when they become airborne, cause irritation in the lungs.Even for those who dona€™t suffer from a respiratory condition feel the red tidea€™s effects. Some species of dinoflagellates produce toxins that are among the most potent known to man.
If you have asthma or some other respiratory condition stay away from the beach during red tide outbreaks. Use common sense-if you are particularly susceptible to irritation from plant products, avoid red tide water.
However, regardless if red tide is in the area, eating distressed or dead animals is discouraged; the cause of the organism's strange behavior or death cannot be absolutely known.
The sheer volume of oil spilt was unprecedented, as were its profound and lasting effects on a large geographic area. In this regard, they speak of a literal sea change regarding the methodologies and modalities, process and procedure, science and technology that are now accepted by many of the nations of the world. More importantly, this issue also triggered a variety of concerns about the overall condition of the Gulf of Mexico. These various perceptions and insights, when considered in the aggregate and within a much larger context, have allowed to surface an assessment of the GOM which can no longer be denied or ignored. If one just considers what the Mississippi River dumps into the GOM on a daily basis, it is easier to grasp the enormity of the problems confronting every stakeholder. Deliberate reference is made to the strength (or lack thereof) of the immune systems of those who passed or tool ill. The direct effect of eating meat are well known and include heart disease, viruses like avian flu, bacteria for example E.coli and salmonella as well as prion proteins like mad cow disease.
Instead of red tide, scientists call these events harmful algal blooms or HABs.Seawater always contains tiny plant-like organisms called algae. While some algae isn't harmful, scientists believe HABs (red tide) have toxins that can harm sea life. Usually humans are affected by red tide when they consume fish that have been living in those red tide toxins.
In Spanish class we were watching a clip about these children who lived in Mexico and what their family would do every single day.
Humans near the bloom may experience coughing, sneezing, itchy skin, and teary eyes.According to Mote Marine Laboratory, the blooms can form out in the open ocean, up to 50 miles off shore, to the intercoastal waters and beaches of Florida.
These harmful algal blooms, or HABs for short, pose a serious and recurrent threat to human health, wildlife, marine ecosystems, fisheries, coastal aesthetics, and the Florida economy. Pets can also be affected and should be kept away from red tide affected water and shoreline.
There are other major sources of water pollution in the GOM which have also became apparent, particularly since the eye-opening 2010 BP oil spill. The most obvious types of pollution entering the GOM are conveyed in vast amounts from various sources throughout the American heartland. Likewise, a whole assortment of pharmaceutical drugs, over-the-counter medications, nutraceutical products, as well as all the chemical compounds utilized in the typical American household eventually find their way into the sewers of the nation’s midsection. Also, the dead fish on the shoreline create a breeding ground for bacteria and cause bad smells on top of the toxins. Countless kinds of harmful contaminants and toxic chemicals find their way into the Gulf via the Mississippi which comes from many different sources. We hope you continue to WONDER about keeping yourself and sea life healthy and happy in their habitats! It is usually somewhat localized, meaning there may be a bad outbreak in Sarasota, while the beaches of Fort Myers are completely unaffected. These operations usually have thousands or tens of thousands of animals in close confinement at any one time.
Stepping on the fins or skeleton of a rotting fish with your bare feet will cause a very painful injury and possibly a very nasty and dangerous infection.
Scallops are ok to eat as long as you only eat the muscle of the scallop, do not eat whole animals.
The results of such farming methods have implications for the surrounding area as well as globally. For example, the Florida Gulf Coast often experiences harmful algal blooms of a type of algae called Karenia brevis, which produces toxins called brevetoxins.Blooms of Karenia brevis can discolor the water, turning it yellow, orange, pink, brown or red. Scientists don't like the term red tide, however, for several reasons.Harmful algal blooms don't always discolor the water and, when they do, it doesn't always appear red.
This is why scientists prefer the more accurate term harmful algal bloom instead of red tide.Harmful algal blooms are called harmful because the toxins produced by the blooming algae can kill millions of fish and other marine organisms.

One tell-tale sign of a harmful algal bloom is a beach covered with dead fish.Harmful algal blooms can also be harmful to humans. Some experts also believe there may be negative effects associated with breathing the air near or swimming in water during a harmful algal bloom.Because of the effects on marine and human health, as well as shoreline quality and the fishing industry, scientists are trying to learn more about the causes of harmful algal blooms.
Some believe they're simply natural occurrences caused by the seasonal shifting of ocean currents.
Others believe human factors, such as pollution, may also play a role.Algal blooms of non-toxic algae are not necessarily harmful. In fact, they're often beneficial because they produce more food — the algae — for the marine life that feeds on them.Scientists have learned that even harmful algal blooms may have benefits, too. For example, even though some fish are killed, scientists have noted that other marine populations seem to increase.
This has led some scientists to theorize that harmful algal blooms may be one of nature's ways of balancing the populations of various marine species. Although the lagoons are coated with either cement or plastic, these protective layers often crack and cause the slurry to leak in to the ground. The manure is also sprayed on to certain crops as a fertilizer due to its high nitrogen content Often this spraying causes the manure to seep in to the ground water and often drains in to lakes and streams. So, leakage from lagoons and seeping nitrates from manure fertilizers enter our water systems. These nitrates have a serious adverse effect on human health and particularly on infant health. Increased nitrate and nitrite levels of drinking water have been associated with an increase in spontaneous abortions as reported by the Center for Disease Control as well as blue baby syndrome.
Blue baby syndrome also known as methemoglobinemia is caused when ingestion of nitrates cause the blood to become depleted of oxygen. In adults, studies by scientists Wolfe and Patz of the John Hopkins School of Public Health revealed that long term consumption of nitrates can lead to stomach, ovarian, liver and central nervous system cancers or tumors. As manures decomposes the bacterial anaerobic process produces nitrogen based gases as well as hundreds of other noxious gases including ammonia and methane.
The detrimental health effects from these gases are varied and it has been shown that ammonia can cause asthma.
Nitrogen oxide gases also reacts with other chemicals to form O3 compounds which cause respiratory tract infection as well as reduced lung function. Nitrogen oxides can also worsen common viral infections and aggravate asthmatic conditions. Some studies show that children who are raised in elevated nitrogen oxide or ozone compound areas have a 40% increased chance of developing asthmatic conditions. As these industrialized farms set up closer to urban areas with large population the effects of the meat industry on human health becomes more evident and poses a greater risk. These effects however are not localized as wind can carry contaminants over large areas and water supplies as well as water ways travel over long distances. The first is directly from anaerobic decomposition of manure, predominantly from pig waste.
Hydrogen sulfide is by far the most dangerous gas of all those produced from manure; even at low concentrations it can cause sore throats, seizures and comas. Continued exposure to hydrogen sulfide can cause loss of life and such incidents do occur on a yearly basis at swine waste processing plants.Studies measuring the air quality at livestock facilities showed that hydrogen sulfide exposure was also associated with increased occurrence of headaches and respiratory tract infection, there were also adverse effects on unborn fetuses.
The fertilizer run of from farms as well as leakage from manure lagoons finds its way into the ground water as well as the rivers and lakes. The nitrogen in the fertilizers causes a massive spurt of growth in the amount various algae or phytoplankton, this causes the amount of oxygen in the water to decrease and hence the marine suffer and die. As the organic matter from the marine animals decomposes this further reduces the oxygen levels of the water creating large areas of water with no life known as dead zones. In such extreme anaerobic conditions ocean bacteria will use sulfur as an energy source, this chemical process produces hydrogen sulfide as a waste product. This problem is further amplified by the rising temperatures of the seas due to global warming, as warmer water hold less oxygen thus leading to increased hydrogen sulfide production.
It is actually this very process of that is blamed for one of the great extinctions that occurred 250 million years ago during the Permian period. For example in Florida in the Gulf of Mexico blooms of a marine dinoflagellate have been known to turn the water red just by the huge amount of the organism present in the water, this is commonly known as red tide and is caused by the phytoplankton species K. Experiments conducted by the National Center for Environmental Health showed that brevotoxins are powerful bronchoconstrictors and can cause respiratory symptoms to those exposed, this would be particularly harmful for those suffering from asthma, potentially triggering an attack. Manure and waste contains many microbes, bacteria and viruses, all of which can make us sick if they find a way in to our water.
There are many such microbes a lot of which are water borne and infectious even at low concentration.
Some like E.coli may remain viable for up to 260 days in a water reservoir, some are even resistant to treatment as they have become resistant to antibiotics. In one such outbreak that occurred in Walkerton, Canada 2,300 individual had gastroenteritis, 65 people were hospitalized, 27 developed long term kidney conditions and there were 7 mortalities. Apart from the staggering human cost the financial cost was also significant at US$155 million. Evidence suggests that the cause was manure run-off from a nearby farm that had entered the water system. Indeed a study from the Center of Disease control shows that an increase in the cattle population per hectare also causes a subsequent increase in the number of infections.
Outbreaks such as these are not a rare event just in British Columbia alone there have been 29 such events since 1980.
