Chasing Coral
Chasing Coral is a Netflix documentary film chronicling the lives of corals for over two months using manual timelapses every single day. The team behind this decided to document the coral reefs found in Lizard Island and New Caledonia after failing to get good images in Hawaii and the Great Barrier Reef. The whole documentary centered on the death of coral reefs due to the warm temperatures of the oceans brought about by climate change. One of the greatest factors of warm oceans is the greenhouse gases transferred in the ocean which includes carbon dioxide. Carbon dioxide, which humans emit in the atmosphere, has the capacity to trap heat and 93% of this goes to the oceans.

Their flesh gradually becomes clear and their white skeleton becomes visible. Moreover, their whole body would be covered by fuzzy microalgae. Second, some corals in New Caledonia were found fluorescing with vivid colors. This is in fact a chemical sunscreen they secrete in order to protect themselves from the heat they are experiencing. In a way, their brilliance can be a tool for people to notice them and their current situation or as what one scientist said in the film, it is an “incredible and beautiful face of death”. Another point explicitly stated in the film was that corals didn’t really have a life expectancy. However, because of climate change, they die early. It was discovered that some corals were turning white after six months which is definitely fatal to our planet because we may witness the eradication of an entire ecosystem in our lifespan as said by Doctor Ruth Gates. In addition to this, there is a big heat wave travelling near the planet which leaves dead corals in its trail and in 25 years, all of the world’s corals wouldn’t be able to keep up with this heat and they will all eventually …show more content…
These are conflict, poverty, instability, migration, unrest, collapse, capacity, and dependency. This film serves as a wakeup call to the audience because climate change is a very critical problem that people should address as soon as possible. It also explicitly shows that climate change is in fact in our midst and is not just a myth or a theory as some would say. The whole documentary tackled consequences which also have consequences. This in turn somehow forms a chain reaction of consequences which are also interrelated. As a result of these, climate change is considered as an accelerant to instability and a catalyst for conflict. Climate change impacts the basic resources needed by nations to continue and for humans to survive and continue on with their lives. For this reason, civil unrest occurs and wars happen. Militant groups and radicals such as ISIS control and secure their access to what is left of these resources like water so as for people to join their cause. There are also uprisings all over the world where protesters demand food due to starvation from lack of food which resulted from drought and food price increases which affects the global market significantly. Moreover, poverty is also a result of
Coral reefs around the world are in danger. One of the causes is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. This essay will focus on damage occurring to the Great Barrier Reef.
The two essays by Michael Pollan and Curtis white talk about climate change in regards to the relationship between the environment and human beings. Although the two essays share the same topic, they take the subject and engage the readers in totally different points of views. Pollan’s essay talks about global and ecological responsibility being a personal virtue while Curtis discusses the socio-economic or political issues underlying sustainability (Pollan; White). These two essays are very different in terms of voice; however these pieces of writing are both important for people all over the world to read. Climate change and environmental disasters are a real issue. Just this year, there have been more storms, cyclones, earthquakes and typhoons all over the world. One cannot look at the state of many developing counties where the majority of the population is exposed and vulnerable to the effects of climate change. This issue on developing a viable solution for the problem of anthropogenic gases and global warming is long from being found. Not only this, many people do not want to hear about this issue since they do not think it is real. Unless people have tangible proof that their cars, thermostats and aerosol cans are contributing to climate change, they are not going to give up their lifestyles. By synthesizing the two essays, one can see that there is a need for change and that it is not an issue which should be dealt with in terms of ecological factors or even personal virtue. The social, economic and political factors affecting this problem and the move towards real sustainability should also be a topic that will raise awareness.
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.
This website gives a large historical overlook and possible conclusion to the issue of coral reef bleaching. Since the 1980’s episodes of coral reef bleaching and death have occurred almost every year in one or more of the world's tropical or subtropical seas. Bleaching happens in episodes, with the most severe typically accompanying coupled ocean–atmosphere phenomena. Bleaching episodes have resulted in loss of coral
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.
Coral bleaching is exactly what you're envisioning now in your head, white bleached out coral reefs which is far different from the colorful lively structures you're used to. Corals get their brilliant
All over the world coral reefs play an important part in our environment. Not only are the reefs colorful and beautiful to look at but the coral reefs house several different types of fish and other sea creatures. Coral reefs have started to decline over the years due to “climate change, El Nino events, overfishing, pollution and other pressures” (Newnham 1). A healthy coral reef can also collapse due to a natural disaster (Newnham 2). There can be several different reasons why a coral reef has started to decline or has been destroyed.
A big change that has occurred in the oceans all over the world is the Coral Reefs are dying and are predicted to be dead by the end of the century due to the rising acidity of the oceans caused by many different threats to marine ecosystems. Coral reefs cover less than 0.2% of our oceans but they contain 25% of the world’s marine fish species according to Endangered: Biodiversity on the brink, 2010: pg.45). If this is the case that means by the time the end of the century comes around we will have lost close to 25% of the worlds marine ecosystems.
Oceans cover 71% of the earth’s surface. The talk of climate change can often seem to focus on what is happening in our atmosphere, but there is a lot of change going on in our oceans. The oceans have absorbed 90% of the excess heat and 28% of the carbon pollution generated by human consumption of fossil fuels (Nuccitelli 2015). The purpose of this paper is to show how the effects of climate change effect the coral reefs in our oceans, with a focus on the coral reef systems in the Caribbean and of the Great Barrier Reef. The Caribbean coral reefs are well known to have suffered more damage between the two reef systems. That’s not to say that the Great Barrier Reef has not suffered its own damage. It has and will continue to suffer in the future.
The leading natural cause of destruction among the coral reefs is global warming. Global warming causes the bleaching of coral reefs to occur. Bleaching is a response to stress by the coral reef that happens when the water becomes to warm. The coral then put out a brownish zooxanthelle which causes them to lose their color. Without the zooxanthelle, the corals cannot provide nourishment for itself and th...
Climate change has been affecting coral reefs in a negative way. If the climate continues to get warmer more of our coral reef become bleached, the structure of the reefs will become weak, and algae that keeps coral healthy will die. In the essay, “A framework for understanding Climate change impacts on Coral Reefs” by Joshua Clinner (2016), he emphasizes our climate change has become one of the long-term threats to coral reef. The article “Climate change and human impacts are damaging the world’s coral reefs”, which didn’t include an author (2001), states that the sea temperatures throughout the tropics has increased dramatically leaving much of the coral unhealthy. Spencer Hall (2008), discussed in his article “Coral Reefs and Climate Change”, how the increase in climate change puts a lot of stress on coral reefs because they are very sensitive to the change of temperature. Rigel B (2003) states in his essay, “Climate Change and Coral Reefs”, that coral reef has already been negatively impacted by
There is little doubt that the current international regime is not effectively protecting coral. The statistics speak for themselves. 19 percent of the earth’s coral reefs have already been “seriously degraded or lost.” Over 60% are under “immediate and direct threat.” 90% are expected to be at risk by the 2030s. And by 2050, nearly all coral reefs will be in danger.
This reef is off the coast of Queensland, Australia. It stretches more than 1,800 miles and tops 40 miles wide in some areas of the coral reef. This reef is so massive that you could see parts of the reef from outer space! This reef is made up of over 600 types of hard and soft corals; and over 3,000 individual reefs systems. This coral has 30 species of whales and dolphins; 1,625 species of different types of fish, 33 species of sharks and rays. There are over 100 islands making up the coral reef; here are 6 out of the 100 islands that make up this reef. Haggerstone Island, Heron Island, Brampton Island, Bedarra Island, lizard Island and, Hayman Island. This reef has many different cities that surround the coral, here are 4 out of the many cities that surround the reef; Cairns, Townsville, Rockhampton, and
Nestled in tropical ocean waters, coral reefs provide valuable resources to both human and marine life. Coral reefs are estimated to contain one-quarter of the undersea world's diverse species while covering less than 0.2 % of the ocean floor. However, coral reefs are in serious danger due to both natural and man-made causes (Edmonds, 1998).
In conclusion, I would like to say that before writing this paper, I had no idea how important coral reefs were to the earth. I have learned a lot and I think that if more people were informed about the positive capabilities of them, humans wouldn't be so careless about them.
