Phytoplankton Decline

It was Mihaljo Mesarovic, the author of “Mankind at the Turning Point”, who once said “The Earth has cancer and the cancer is man”. He was definitely onto something. In fact, humans have had a major negative impact on the world’s marine environment. Throughout recent human history, it has been obvious that the wellbeing of the marine environment has been in jeopardy. Pollution of the ocean, overfishing and the greenhouse gases these are all the aspects that can cause the destroying of the precious environments, such as reefs, sea-grass and coastal habitats. According to the essay and interview “Seafarming at the End of the World”, written by Peter Meehan, he presents the fact that human impact on the ocean is the main reason that causes the awful situation of marine ecosystem and organisms.

The state of Florida is the region most susceptible to the effects of global warming in this country, according to scientists. Sea-level rise alone threatens thirty percent of the state’s beaches over the next 85 years. Climate change and global warming refer to the body of scientific evidence showing that the earth’s environment is warming due to human activity, including the burning of fossil fuels and deforestation. It is accepted science all over the world. Climate change in Florida has many effects such as the increase of our sea level and global warming this issue will cause a dramatic change in 2050.

Florida’s environment is a sub-tropical atmosphere, with hundreds of species of animals. Along the coast is were Florida’s natural wildlife and vegetation thrive; however, Florida has a serious issue that impacts its coastal environment. Each year global warming contributes to rising sea levels across the globe. Although Florida’s Coastal environment has survived for thousands of years, the increasing sea level along the gulf coast over recent years, has caused severe damage. Additional research is needed to understand the impact of rising waters on Florida’s Coastal eco-system.

People living in Miami are in the face of danger, and for the most part they are not aware of it. Due to high population, Miami is the fourth largest city to become affected by sea level rise. (Ankum et al.) In the next 32-50 years, sea level is expected to rise by as much as two feet. (Ankum et al.) This two-foot rise will have detrimental effects on the urban settings of Miami. The amount of soil erosion that is undergoing at our beaches will greatly increase if a two-foot rise occurs. At a four-foot rise, road connectivity would begin to become affected. At a six-foot rise, Southern Florida would no longer be habitable as it would, for the most part, be underwater. Not much is being invested in mitigation efforts, most of what is being done are short term solutions. Instead of coming up with ideas to prevent and try to slow down the effects of climate change on our environment, we are focusing on ideas such as building up a sea wall, relocating power plants, and redesigning structures.

“Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day” (Ocean Portal, n.d). This number is expected to increase forevermore as atmospheric carbon dioxide levels increase and the effects of Climate Change worsen. At first, the idea of our oceans absorbing carbon dioxide from the atmosphere may sound great, however, scientists have been quick to learn otherwise. High concentrations of carbon dioxide in oceans can have detrimental effects on the ocean chemistry and marine ecosystems (Hardt; Safina, 2008). Marine ecosystems are greatly complex and depend on every marine organism to function properly, any change can put the whole ecosystem at risk. For example, the increase of carbon dioxide in our oceans is responsible for the dissolving of “brittle star” skeletal parts, which has in effect caused food scarcity for many fish, crabs, shrimp, and other starfish (Leu, 2013). Furthermore, these marine ecosystems are very important to humans- being the primary food source for millions around the world and having an economic market worth trillions of dollars (Hardt; Safina, 2008). Part of keeping these ecosystems safe is to understand how they work and how projected changes can harm marine organisms.

Millions of people living in Florida could be forced to move, it the coastal waters keep rising. While this news is not old, it is happening at an alarming rate and people are already seeing the damages of the rising waters. There are four counties in Florida that would be hit the hardest, Miami-Dade, Broward, Pinella, and Lee. It is believed that in those four counties alone, over 521,000 people will be affected, according to LiveScience.com,

Miami, Florida experiences a great amount of natural disasters; however, one of the largest disasters Miami fears is affects of global change. Rising global temperatures scares most environmentalist in the Miami area, because rising temperatures results in rising sea levels. So, what is the problem with rising sea levels? Well, environmental specialist has made predictions that the rising sea levels could submerge the beaches of Miami.

Dutch expert Henk Ovink once told New Times that “Miami will no longer be a land city, but a city in the sea.” (Weiss, 2015). There has been a rise of 10 inches in sea levels in the 19th century. As of today, the East Coast and Gulf of Mexico of the United States are the two areas that are more prone to sea level rises (Infographic, n.d.). Miami is the fourth-largest population in the world that is susceptible to this predicament. On top of that, it seems that floods are becoming more frequent and more damaging than ever. It is estimated by the end of the century, Miami can get another rise of 6 to 10 feet of water (McKie, 2014). There are clear signs of the tides taking effect in the city. Homes and shops are being surrounded by water in

Modern fishing methods have first and foremost created serious problems for ocean ecosystems. Scholastic Scope states, “The populations of almost all fish species that we eat have shrunken, some drastically, as a result of overfishing, or catching fish faster than they can reproduce” (Dignan 14). Sadly, fish cannot reproduce fast enough to sustain their populations when different fishing techniques drain their ecosystem’s health. Because humans are relatively new organisms, fish, a much older species, have not adapted to modern fishing techniques and overfishing in the sea. Therefore, oceans are at risk because fish cannot compete with newer, more efficient fishing techniques produced by humans. Climate change is furthermore another major threat to oceans. As published by Scholastic Scope, “Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems” (Dignan 14). Although climate change may now be a controversial issue, its footprint and effects have no doubt left their mark. Powerful and destructive climate change has also been the culprit of extinction for many other animals such as the marine animals during the Permian-Triassic extinction event. Since things often repeat itself in history, the ocean could have a Holocene extinction event, which would completely

The marine biome is tremendously impacted by the effects of climate change. The sea levels have been rising, the water temperature has been rising, organism’s habitats have been destroyed, the tides are coming in stronger, the ocean is acidifying and many more things that will end up impacting all of us and the rest of the world in a very big way. Climate change is real and the proof is right in front of us. Flooding in major cities, el nino, more frequent natural disasters, wildfires, heat waves, and so much more. The facts are right there, we have just been too blind, too egotistical, to imperfect, to realize that we have changed the world. We did not mean to but we did so we need to fix what we caused.

Cities in Florida also lack the technology, money and manpower to keep back the seas by themselves (“Sea rise”, 2015). Despite warnings from water experts and climate scientists about risks to cities and drinking water, skepticism over sea-level projections and climate-change science has hampered planning efforts at all levels of

Anthropogenic activity has led to greatly increased emissions of greenhouses gases. Increased temperatures, acidification and stratification are all affected by increased carbon dioxide (CO2) concentrations. These symptoms of climate change have direct and indirect effects on to marine ecosystems, all of which start at the major primary producers of the oceans: phytoplankton.

While many treat the oceans as a convenient area to abuse, due to years of using the oceans as an unlimited source of food, a path for transporting goods, and a place to dump litter in, there are many growing issues due to these problems that could lead to the loss of the oceans completely. As a result of several problems caused by mankind, including unsustainable fishing practices, pollution, and indirect impacts, the marine ecosystem has changed in a drastically negative matter, which can later impact mankind due to the loss of many keystone species, and has the potential to negatively affect mankind as a whole. By taking the ocean for granted, we are leading not only the oceans towards disaster, but ourselves as well.

Since the beginning of the human race, the ocean has been a major source of food. People near the shores have been taking of advantage of the ocean’s rich and diverse source of nourishment for centuries, both as a source of food and a livelihood. However, since the dawn of the industrial age, humans have begun to take from the ocean more that it can give. As a result, the ocean can no longer provide the human race with the abundance that it once did. As technology rapidly advances, populations skyrocket, and global warming spreads havoc, the ocean’s biodiversity and once abundant supply of fish is dwindling, calling marine scientists and experts to race to find solutions that will restore the oceans health while battling world hunger.

As our Oceans begin to saturate from Human’s carbon dioxide pollution, its marine inhabitants suffer as a consequence of our ignorance. Rises in atmospheric carbon dioxide levels result in ocean acidification affecting the marine life inhabiting areas such as coral reefs, which are also being bleached by the change in carbon dioxide levels. Current studies led by marine biologists suggest the ocean's carbon dioxide levels are off balance and are destroying the marine ecosystems, by stunting fish growth as well as bleaching the coral. Ocean acidification has changed the ocean for the worse, or so it seems. Other evidence suggests marine life can adapt to the change in the oceans acidification level, but not all species will be fortunate enough to acquire evolutionary advancements. On-going atmospheric carbon dioxide pollution will continue to saturate our oceans and change the marine life that inhabits it. Humans must strictly govern pollution as well as instate fishing policies to protect our oceans and the marine life being neglected by humans who are simply ignorant of the crisis at hand.
