The world’s oceans are very negatively impacted by human activities. Fish are less abundant because of overfishing and destructive fishing practices. The dumping of human waste (trash, untreated sewage, oil, chemicals, etc.) pollutes shorelines and ocean waters. Coastal developments on and around coastlines disturb, alter, and destroy marine habitats. Human reliance on oil and non-renewable energy sources (ex. burning of fossil fuels) contributes largely to global climate change, with huge implications for the oceans and marine species (sea level rise, ocean acidification, coral bleaching, etc.). Fortunately, however, negative impacts have given rise to restoration, conservation, and preservation efforts, (restoring fish populations, protecting
In Colin Woodard’s “Ocean’s End: Travels Through Endangered Seas”, major environmental problems facing our planet are exposed. Woodard exposes the creation of dead zones from pollution, the killing of our coral reefs and the negative effects of the rise of sea-levels. The common theme throughout this book is the dark fate of Oceans and marine life as we know it. Although it may seem like our bodies of water are limitless, vast, and indestructible, they are not. In fact they are vulnerable, and we as humans are destroying them daily through our reckless actions. Major sources of the depletion of our oceans is constant pollution, global warming, and harmful fishing practices.
People are polluting the oceans which not only affects us but also affects the beautiful underwater habitats and interesting sea creatures. Two billion people within 30 miles of the coast create 100 metric tons of coastal plastic waste (Doc.1). This plastic waste can get caught around sea animals, injuring them or even killing them (OI). Oils spills can really hurt marine life (Doc.2). Some creatures could eat it or get covered in it. If the fish eats the oil and then someone or something eats the fish they could get extremely ill. When there are excess nutrients in the water algal blooms occur, which is when algae has too many nutrients and reproduces in large numbers, this can also hurt people (OI). For these reasons and many more we should
Marine pollution is not a new phenomenon, but our acknowledgement of its impacts and severity is relatively new, with the first laws and discussions to counter it only appearing in the 1950’s. For much of history, it was thought that the oceans were so large that any pollution created would be negligible and easily diluted (Marine Pollution). Since, countless research and laws have been implemented in order to preserve our marine ecosystems because of how crucial these ecosystems are to humanity.
The alluring azure ocean, the brisk ocean waves, the lemon yellow sand all show a paradisiac view of the Tasman Sea in Australia. However looks are deceiving. Walking 20 feet from the shoreline, a nauseous view disrupts the majestic scene. I see a plethora of dirty Poland Spring water bottles on the shore. An ash colored seabird lies with a murky bag over its head, lifeless. The dead sea bird was doomed to die of human waste because plastic is being dumped in the oceans and slaying marine life.
The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.
Oceans have affected the environment by hurting animals, people, the environment itself and NOW the plants. Believe it or not, but when garbage affects our plants it also affects our animals, humans, and environment, like a chain reaction. Any plant can be affected by this pollution.
Earth's oceans are dying. “About 80% of the ocean around the world is polluted with chemicals industrial and residential waste, all of which comes from the land” (“Marine Problems…”). Pollution is mainly coming from the people. Marine pollution should be stopped because it is the cause of many problems and if something is done about it, people will see an increase in sea life and healthier waters. It makes its way into the ocean and kills marine life. Ocean pollution is affecting the way of fisherman and their everyday lives. It is also very bad on the community because pollution is very bad on tourism. Ocean pollution should be stopped because it is poorly affecting marine life, it is not good for fishermen, and is very bad on tourism.
In 2009, Dr. Sylvia Earle wrote The World is Blue to educate and alert the reader about human impacts on marine ecosystems. Through this book she conveys her passion and methodical arguments concerning the importance of the conservation of the ocean, which encompasses approximately 80 percent of the earth’s surface. Dr. Earle states “the ocean touches you with every breath you take, every drop of water you drink, every bite you consume” (17). This statement emphasizes the significance of the ocean, not only for marine life, but all life forms on earth. The book implies that currently in today’s world, the conservation of the ocean requires a global effort to reduce human damage from the past generations. Using facts gleaned from credible scientific resources, she defines the problems of overfishing, bycatch, and pollution. By analyzing human impacts on marine ecosystems, Dr. Earle determines successful and unsuccessful solutions to these problems and suggests various ways individuals can change their lifestyles to reduce impact on the environment as a whole.
The oceans face many types of pollution every day, every second. The ocean is our greatest ecosystem and out most valuable resource. A common misconception is that the rainforests are the lungs of the planet however, the majority of our oxygen is made via the algae in the sea. The oceans feeds, hydrates, and provides us with oxygen; ironically enough, despite its monetary value to mankind, it is what is treated the worst. For ages we have been dumping our trash, chemicals, and waste into the oceans with no fear or regret, almost an “out of sight- out of mind” mentality. People once and still assume that the oceans are so vast that all of the pollution is diluted and would be dispersed through out, going unnoticed. However, dilution is a myth and an idea that renders ocean dumping to be less impactful. Even so much of the man made pollution is becoming even more concentrated and have entered our natural food chain. However vast the waters of the ocean are, they are not meant to house all of these external factors. There are many alternatives to marine pollution including recycling, finding alternative trash dump sites, cutting down on harmful chemicals for agriculture, and most importantly having the ability to recognize when a problem is developing and counter act, immediately.
The world we live in is so vast and exciting. Seventy percent of our world is liquid water we call the ocean. In the ocean there are many creatures that each are unique in their own way. However, it is possible that in our lifetime, many marine organisms will become endangered or possibly extinct. The loss of these mejestic marine creatures will be caused mainly because of human advancements in which fossil fuels are used to produce energy. Biodiversity is greatly affected by this increase in acidity. As the ocean acidifies, multiple social and economic issues arise. As humans, we rely on the ocean for almost everything. Much of our food, clothing, cleaning products and cosmetics come from the ocean. With the loss of
Oceans cover approximately 75% of Earth 's surface and are vital to this planet and the people who inhabit it. Oceans provide food, natural resources, and recreation for nearly everyone in this world. Unfortunately Oceans have been receiving mass amount of pollutants including oil spills, toxic waste dumping, and industrial dumping. These pollutants will have negative impacts on the wildlife in the ocean, as we are seeing already with the Coral Reefs, and soon enough it will begin to affect our lives as well.
In a world of continuous progress and evolution, climate change and pollution is a leading problem in the world. Both directly and indirectly, pollution happens on a global scale every single hour. The world’s oceans are among the most affected by constant dumping of chemicals. The Deepwater Horizon spill in 2010 released 4.9 million barrels of crude oil into the Gulf of Mexico, the largest spill in US-controlled waters.1
Marine biologist play a key role in understanding climate change and identifying sustainable and profitable ways humans can use the sea and its resources. Marine biologist understand marine organisms needs in their habitats, ultimately helping protect species and reduce human threats. As experts in understanding marine habitats, marine biologist often form essential parts of relief teams. They respond to oil spills and chemical leaks, helping other scientist restore normalcy to local habitats. Sometimes, marine biologists influence other spheres, such as economics and law. They might analyze the effect of sonar on whales and seals, for instance, recommending best practices for reducing harm on those sensitive populations. Marine biologists understand how the ocean supports basic needs, and in turn relay that information to lawmakers, who establish protocols regarding human use of ocean waters and marine organisms. Marine biologist help develop ocean technology too, improving waste elimination, energy sourcing and extraction of key sources. A brief review of components of the marine environment, world food resources, climate control, air and water quality, transportation, and the ecosystem balance are important features that are studied by marine biology. So, understanding why marine biology is important is foundational to integrating a balanced approach toward management of the sea and proper stewardship of organisms,
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.
Marine fisheries make up some of the largest ecosystems/habitats that span from the coastal regions all the way through the various oceans of the globe. In addition, the habitats and ecosystems of marine fisheries contain some of the most diverse groups of organisms worldwide just because of the sheer amount of the planet’s surface that the oceans cover. Although the range and diversity of marine fisheries are vast, they are declining at increasing rates. There are many factors that have led to this decline which include climate change, pollution, and the introduction of invasive species into particular habitats. However, the two largest factors behind the collapse of marine fisheries are directly correlated with human interaction with the marine fisheries. One is the overexploitation by the fishing industry, while the other is habitat alteration (mainly around the coastal areas) (Layman et. al 2011).
