Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health.
Not to mention, another environmental threat that this fascinating animal, the blue crab, faces is climate change. Corresponding with the text, “Climate change is another major threat to life in the oceans. Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems,” (Digan 14). This confirms that another ecological peril that this fascinating animal, the blue crab, faces is climate change because the blue crab resides mainly in the Chesapeake Bay. They are threatened by climate change as it creeps closer like a cat stalking its
What you tend not to hear about are the potential indirect belongings of ocean acidification on food web dynamics, the biology of fishes, and even sound in the ocean environment which has huge effects for marine mammals. The list of possible indirect effects is long and hypothetical and research into this aspect of ocean acidification in its first phase. Dues about the indirect effects of ocean acidification are also stiffer to prove than the direct effects shown to harmfully affect calcifying
It bleaches the corals, which then harms marine life, upsets the ecosystem, and effects the economy. Even though we may not realize or appreciate them, coral reefs provide so much to our world. Without them, people would have a difficult time going about their day to day lives and would struggle to get
Why are experts concerned? Coral reefs are delicate. Overfishing and pollution can harm them. They can also be affected by changes in water temperature caused by occurrences like global warming. What Are Reefs?
One of the leading causes for reefs to be endangered is due to the invasive lionfish. The lionfish’s impulsive eating habits are threatening our sea life of the reefs and decreasing our fisheries economically. According to Lionfish Hunters, the green side includes the cleaners that maintain the health of the reef and the health of other fish such as “grazers.” The grazers are the parrotfish, goatfish, wrasses, surgeonfish, and tangs.

Coral reefs are undeniably important for numerous reasons. They are ecologically important by supporting and providing habitat for marine community, act as wave-breakers to protect the shores from strong currents, generate income for humans and provide many other ecosystem services (Sutton 1985, Demirbilek and Nwogu 2007, Moberg and Folke 1999). Yet, corals reefs around the world are increasingly being destroyed at an unprecedented rate through overfishing, fish-bombing, increasing coastal development as a result of growing human population and others (Munro and Munro, 1994, Grigg and Birkeland 1997, Hoegh-Guldberg et al. 2007). Despite this global phenomenon, our understanding pertaining to how the complex marine ecosystem responds towards
Most of the waste produced on land is either intentionally or unconsciously discharged into the oceans. Marine pollution and aquatic debris can utterly destroy the oceans causing extinction of the marine creatures. Innovative techniques should be implemented in the law to prevent the marine environment from any further damage. In order to improve the marine environment, the government and the Environment Public Authority of Kuwait should take immediate actions that can influence the society and help in minimizing aquatic debris and pollution. Aquatic littering and marine pollution can be caused by a number of different sources.
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. •
Coral diversity, calcification, coral cover and coral development are all being impacted by chemicals reaching the reef (Amelia S. Wenger, 2015). If the amount of chemicals reaching the reef continues to increase, the reef will continue to diminish, coral species will become extinct and reef fish will lose their habitat, forcing them to relocate or
The sea level rise also threatens the source of drinking water of Miami Beach, the Everglades and the large freshwater wetland South Florida. Not to mention, that great part of our economy is produced from the tourism. Miami is full of buildings, most of them luxurious, very close to the sea, and the tourism is vital and known worldwide, to the point that climate change could greatly harm tourism in Miami. And, eventually, if they don’t take action over this situation, the tourists will search for another place where to take the sun without wetting their feet when walking down the streets and this will be impacting as well as the residential
One of the biggest problems on our planet at the moment is the 79 million tons of carbon dioxide being released into our atmosphere every day. According to the European Project on Ocean Acidification, one third of all the Co2 that has been released into our atmosphere has been absorbed by the world 's oceans. Without the immense size of our oceans absorbing all this CO2, our atmosphere would suffer from extreme global warming with devastating effects. However, the downside of our oceans absorbing most of the CO2 is that it threatens the health of our oceans and the animals inside it. It all starts off when the CO2 from the atmosphere is dissolved into the oceans.
Incredible beaches, marine life, and weather are just a few of the things that make the Florida Keys an amazing place. The Florida Keys are a string of islands located off the tip of Florida, which protrude out into the Gulf of Mexico and into the Atlantic Ocean. The oceanography of the Keys are unique because of several factors, including the geologic history, the tides and waves, and the effects of natural and man made threats to the Keys themselves and the thriving marine life. The map below shows the stretch of islands and the many reefs that are right off the coasts of the islands (Florida Keys Map) Geologic History Thought to have emerged from ancient coral reefs or patch reefs that had eroded, the Keys are a bit of a mystery in terms
