INTRODUCTION:
Humans are reliant on the ecosystem for many ‘ecosystem services’, some of which are: purification of air, cleaning of water and pollination of crops. Humans are also reliant on the ecosystem for the production of fertile soil, mineral nutrients, meat, etc.
Human activities tend to affect the ecosystem in both negative and positive ways. The negative, these days is more profound. Human wastes are released into other ecosystems which causes them to become unbalanced. Sometimes the levels of waste become harmful. Examples of human waste that affect ecosystems come from:
• households
• industries
• agriculture
• gaseous emissions from the burning of fossil fuels
Harvesting also cause imbalances in the natural ecosystems and food chains of other species. As an example, harvesting timber can lead to loss of habitat and soil erosion, while harvesting fish from the oceans can cause endangerment of species and breaking of food chains.
In many parts of the

Coral reefs are dying around the world. In particular, coral mining, pollution (organic and non-organic), overfishing, blast fishing and the digging of canals and access into islands and bays are serious threats to these ecosystems. Coral reefs also face high dangers from pollution, diseases, destructive fishing practices and warming oceans. In order to find answers for these problems, researchers study the various factors that impact reefs. The list of factors is long, including the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, biological virus, impacts of dust storms carrying agents to far flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal
The increase in the changes of climate is affecting the delicate coral reefs. Coral reefs depend on a balanced temperature to thrive. The increased water temperature due to global warming are causing the coral to become bleached. They turn white and die. This also kills the wildlife and algae that live in them.
This book explores the many living things that make up the complex environment world we live in. The text discusses how ecologist study living things, the climate, the Earth, and how they work tother. It contains several pictures with captions to explain how living things interact in the environment. Batten, M., & Doyle, B. (2008). Aliens from Earth: When animals and plants invade other ecosystems.
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.
Recently, because of the downturn of sharks, those coral reefs and seagrass
Research has shown that sunscreen is having a negeative impact on the health of coral reefs. Trash is dumped and left on beaches daily. Oil spills and boat use disrupt fish and marine life. Erosion has become a big consern for the stability of beaches.
Calculations for tourism for the year of 2015 are unavailable at this time, but for the year of 2014, the reef received a total of 2.19 million visitors. It is a well – known piece of information that there is a global climate change going on where there is a rise in CO2 in the atmosphere due to higher emissions of fossil fuel and more deforestation occurring. The ocean then absorbs more of this CO2, which in turn raises the acidity, which in turn creates a poor environment for the coral to live and recover from bleaching that has already occurred. This change in acidity also affects the calcium carbonate that corals use to build themselves. (“Climate Hot Map- Global Warming Effects Around the
The population of the largest and most significant vertebrate plants feeds, including sea turtles, dugongs, have been severely decimated by the impacts of humans on the reef. The loss of these vital animals has and will more severely disturb the coral reef food web in a significant manner, although the specific impacts are not clear
Oceans are peaceful, majestic, and filled with amazing and vibrant color. A lot of the prostown beauty in oceans can be credited to coral reefs. Lately though, natural coral reefs have been dying for various reasons, and some people believe that artificial reefs can help not only the natural reefs, but other surrounding ecosystems in their environment. Various articles use rhetorical techniques in hopes of enhancing their articles about whether or not artificial reefs are helping or harming the oceans. The first article, “Concern Lingers on Success of Artificial Reefs”, was written by Charles Q. Choi, and for Live Science, looks at both the pro and con side of artificial reefs.
When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely.
About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
Therefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
In this research paper we will explore more about coral reefs and their importance. Coral reefs are communities of living organisms. They are made up of fishes, plants, and many other creatures. They have been around for millions of years: less than the 0.1% of the world’s ocean floor Is covered by coral reefs, however they grow very slowly, from 0.3 cm to 10 cm per year.
Introduction: Our earth is the most precious gift of the universe. It is the sustenance of ‘nature’ that is the key to the development of the future of mankind. It is the duty and responsibility of each one of us to protect nature. It is here that the understanding of the ‘environment’ comes into the picture. The degradation of our environment is linked with the development process and the ignorance of people about retaining the ecological balance.
Balance of natural processes like pollution is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life. •
