Recommended: the importance of mangrove
1.0 INTRODUCTION
Australia has a total of 11,000km of mangrove-lined coast, which makes up 18% of the Australian coast-line, but only 1% of Australia’s total forest cover. Mangroves play an important role in the oxygen we breathe today, they are also a host to at least 70 different species of crustacean and roughly 75 different species of fish and over 100 different species of molluscs, and even polychaete worms and 230 species of birds. Some species only live in mangroves during high-tide such as sea snakes, turtles and even crocodiles. All these organisms are being affected by human impact such as sedimentation caused by construction and excavating, water and air pollution caused by large factories releasing chemical waste into the water and air and deforestation a way to make money and clear land to build things like factories or mines. These are just three of the serious issues that put organisms and even people at risk all caused by humans. All organisms are interconnected in their world – no matter how small or how large – there must be a balance with their environment to survive. Just the slightest disruption in the food web such as the removal of one species could end in the removal of hundreds. Rapid environmental changes within an area, biome, or planet can affect the biodiversity and cause mass extinction. That is the huge role that humans play in the biodiversity of this planet.
2.0 THE IMPACT
2.1 ENVIRONMENTAL
Mangroves live in the inter-tidal zone, an area that is above water during low-tide and underwater during high-tide. Mangroves provide a great value to the environment such as shoreline protection, nursery to threatened and endangered species. The mangroves protect shorelines from damage such as erosion, cause...

6.0 CONCLUSION
In conclusion, all organisms are important to the environment they live in, no matter how big or small, there must be a balance to survive. Even the smallest mistake can have a serious effect on the environment around it. Mangroves play an important role in the air we breathe and most people don’t even if we don’t know it, creating awareness for mangrove deforestation can benefit the entire world greatly. The use of scientific equipment to collect and store data in mangroves gives ecologist better understanding in which the mangroves live in, this makes it easier for ecologist and even the locals surrounding the mangroves to take action in maintaining and/or restoring the environment around them.
They also look after the quality of coastal waters by watering down, sifting, and settling deposits, left-over nutrients and contaminants. They are highly productive ecosystems and provide habitats and act as nurseries for all manner of life.
Aside from humans, coral reefs like The Great Barrier Reef are being destroyed by an outbreak
Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people.
Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms. Coral reefs contain only six per cent of the area of the Great Barrier Reef, yet they provide critical habitat and food for numerous species in the ecosystem. However, climate change has already impacted coral reefs in the Great Barrier Reef as corals are very helpless against its potential impacts. Eight mass coral bleaching events has occurred since 1979, triggered by unusually high water temperatures. And because of this, zooxanthellae (photosynthetic algae) leave their tissues and corals will have no more colours hence ‘bleaching’. Without the zooxanthellae, the corals that remain gradually starve to death. Once the coral dies, fish and a multitude of other marine species are soon affected. Rising sea levels and more frequent and intense storm surges will see more erosion of Australia’s coastline, causing community and residential
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
Globally coastal wetlands are disappearing at an alarming rate, the problem is most of society does not realize the value of these precious wetlands. Coastal wetlands provide an important role in the coastal ecosystem. “Coastal wetlands provide critical services such as absorbing energy from coastal storms, preserving shorelines, protecting human populations and infrastructure, supporting commercial seafood harvests, absorbing pollutants and serving as critical habitat for migratory bird populations”(Anonymous, 2011). Coastal wetlands are an economical asset as well as an environmental one.
Although there are many uncertain factor in the study of coral reefs, what we can sure is that the diversity and the quantity of Great Barrier Reef is decreasing under the global warming. No matter coral reefs’ future is more serious or it is optimistic, global warming’s effect on coral reefs is negative, especially for Great Barrier Reef. Disregard of coral reefs’ protection on coastal, there are still million of people relying on the tourism or other aspects of Great Barrier Reef. Contemplating policies that result in [CO2]atm above 500 ppm appears extremely risky for coral reefs and the tens of millions of people who depend on them directly, even under the most optimistic circumstances(Hoegh-Guldberg et al., 2007). People have to take action to stop the steps of global warming. There are many experts predict the future of coral reefs without human action, for example: Without the stabilization of greenhouse gas concentrations, it seems inevitable that many of the world’s coral reefs will become nonaccreting habitats—they will, based on most common definitions, cease to be coral reefs(Mark 2015; Barbara 2015); Eakin :Unless there is concerted action to reduce greenhouse gases,” he warns, “bleaching will become increasingly common and not just during extraordinary weather events”(Dennis
A statistic released by the Marine Science Education Project of the Indonesian Ministry of Higher Education States that “…Reefs subject to land-based pollution (sewage, sedimentation, and or industrial pollution) show 30–50% reduced diversity at 3 m, and 40–60% reduced diversity at 10 m depth relative to unpolluted comparison reefs in each region.” This statistic is alarming because it shows just how much pollution can affect a certain environment. Not only does it affect the environment but it also affects animals, plants and people.
...s are considered as part of a larger watershed, the recognization of the complexity of environmental stresses can be understood. Management plans can be developed to reduce impacts to mangroves, seagrasses and the reef ecosystem, based upon accurate data and a better understanding of the system. EPA is in the process of developing guidance for a watershed approach to coral ecosystem protection.
Coral reefs are well known for their colorful array of marvelous sights including a parade of exotic flora and fauna. They are said to be the foundation for a quarter of marine species, and are a crucial support for human life as well. The coral reef ecosystem is a diverse collection of species (ranging from microscopic to larger-than-life in size) that interact with each other and their physical environment. If any piece of a coral reef is harmed or removed the entire community can be seriously affected, even to the point of collapse. Unfortunately, human impact has resulted in long-term stresses that, unlike the short-term stress of natural disasters, coral reefs are not as capable to recover from. “Approximately half of the world’s coral reef ecosystem resources are considered by scientists to be in 'poor' or 'fair' condition and have declined over time due to several anthropogenic threats” (“Status of Corals” par. 2). Through poorly administered commercial practices, carelessness and ignorance among the common people, and human aggravated natural processes coral reef destruction has become a serious issue afflicting the world’s biodiversity and it’s intricate biosphere mechanics (“Human Impact on the Great Barrier Reef” 1) (“What Are Coral Reefs?” 1).

The degradation of ecosystems and loss of biodiversity is increasing at an alarming rate every year. Humans are certainly not the only reason for this, but they are the main contributors. The well-being of ecosystems affects our everyday lives - consumption and consumerism depend on natural resources. Everything humans use is derived from them, in seemingly indirect and direct ways. Yet despite the fact that humans are destroying the environment, many continue to and neglect to take important measures to protect it.
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
Biodiversity is so important that if any chain or link is disturbed then the whole system will come to a halt. Biodiversity also boosts ecosystem productivity and if it declines automatically our ecosystem also declines as both are interdependent upon each other, where all the species play an essential role in the way ecosystem functions, so local and global species loss could threaten the stability of the ecosystem services on which humans depend. This is an interesting topic as well as a global issue concerning the whole human civilization and their existence. . The said issue as well as many other issues regarding our natural processes cannot be neglected as our present and future depends entirely on the sustainability and growth of this ecosystem and biodiversity. Our ecosystem completely depends on the way biodiversity functions. This is the reason I have chosen this topic and gathered information about how it e...
The marine environment encompasses the sea and estuaries waters, the seabed and its subsoils, all marine wildlife, sea and coastal habitats. Given the importance of the marine environment to the ecosystem, it must be protected, conserved and properly valued. Seas and oceans must be kept biologically diverse and dynamic as well as safe, healthy and productive. The marine environment is a vital resource for life on earth. The marine ecosystem plays numerous fundamental environmental functions: regulation of the climate; prevention of erosion; solar energy’s accumulation and distribution; carbon dioxide absorption; and maintenance of biological control. The marine environment is the greatest source of biodiversity covering 71 percent of the Earth’s surface and containing 90% of the biosphere. Furthermore, it is a great contributor to economic prosperity, social well-being and quality of life. Given its economic and social potential, sustainable exploitation of the marine environment is critical for South East Asian countries.
