The Chandeleurs housed a tremendous amount of birds and wildlife. Also it provided a nursery for marine life. As Katrina roared over the island, it completely leveled the island. Due to the devastation, all inhabitants of the island fled. This event shows how a natural disaster can completely alter an ecosystem (Di Silvestro).
Many shoreline businesses got ruined and many seafood businesses had to be temporally shut down due to loss of sea life around the coast of Samoa. After the tsunami hit Samoa, as well as Tonga, it receded back into the Pacific Ocean, taking a great amount of rubbish along. This polluted the ocean a lot, it was responsible for many deaths of various sea animals. As well as land
Red Tides affect the marine and land life in various ways, the most important of which are listed below 1. Effects on human life: i. Paralytic Shellfish Poisoning (PSP): This happens if fish contaminated with Alexandrium species is consumed. It majorly affects the nervous system and in many cases leads to paralysis. In extreme cases, the paralyses may affect the respiratory system and ay result in death. ii.
Many marine mammals mistake these for food (Greer, Abigail). Plastic kills fish, birds, marine mammals, sea turtles, destroys habitats, and affects animal mating rituals, which can result in devastating results, such as wiping out an entire species (“How Ocean Pollution Impacts Marine Life-and All of
When fish consume the plastic, it will move up the food chain and affect other aquatic animals that consume fish. “Endangered wildlife like Hawaiian Monk Seals and Pacific Loggerhead Sea Turtles are among nearly 300 species that eat and get caught in plastic litter” (“Ocean Plastic Pollution”). If an animal gets caught in plastic, then it could suffocate them. “In 2008, two sperm whales were found stranded along the California coast with large amounts of fishing net scrapes, and other plastic debris in their stomachs” (“Ocean Plastic Pollution”). When an animal eats plastic, it causes their minds to believe that they are full but plastic does not give them the nutrients that they need and will cause them to starve.
Keeping the Ocean Free of Debris Pollution in the Persian gulf is negatively impacting marine life How much are we trashing our ocean? CNN, February 12th 2015. Arabian Gulf coral reefs dying a slow death. Gulf news, June 10th, 2014. Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution.
This leads to the ultimate death of the coral and the homes of many sea creatures. Coral bleaching is a problem that occurs worldwide where scientists are trying to uncover the central causes of the bleaching and how it affects people and the environment. Scientist have conducted multiple
Loss of coral reefs would be devastating to one of the most grand pools of biodiversity in the whole world They help seed the oceans and provide food to a complex web of organisms that lead all the way to man. They act as natural barriers to shorelines, and as they die, coastlines become more susceptible to damage and flooding; tropical storms and high waves would be the ones that could make the most damage if coral reefs were to disappear. Of course, not only we are the ones to be damaged by this, but other animals in the marine ecosystem too, like sharks. Sharks work in the ocean and in coral reefs by cycling nutrients between it and the open ocean, removing invasive species, and getting rid of weak fish carrying disease; if coral reefs were to disappear, then sharks would lose one of their main ways to obtain food and nutrients. And as we all know, if one animal disappears in an ecosystem, the organisms that consumed them would die and affect the food chain so
Dispersants cause the oil to break up into smaller droplets, which become miscible in water. However, these dispersants may result in more ecological harm than good. The chemicals contain nonbiodegradable toxins that can kill fish and migrate great distances. Dispersants also are blamed for the massive oil plumes several hundreds of feet underwater, harmful to all aquatic life, especially fish larvae and filter feeders. Moreover, because of the large volume of oil that has been spilled, the amount of dispersant required and the amount of oil dispersed simply suppresses the problem, rather than solving
How the oceans may die is crucial to understand in order for them to be preserved for the survival of the planet. Numerous human activities generate a staggering amount of grave complications for the oceans and its crucial marine life. One of the most direct human activities that causes rapid decline in marine populations is overfishing. Some of the species
In conclusion, manatees are becoming extinct because people are populating the water that manatees live in which is causing them to die. Manatees are being struck by boats when people drive through shallow water too fast, because they cannot see them in time to move out of the way. Manatees are also becoming extinct because they are eating toxic algae that is produced from the
