Also, the ocean filters the air we breathe, and like said before, supplies 80% of the oxygen we breathe. Pollution causes the ocean not to function properly and oxygen levels can and will diminish. The ocean is also home to medicines that treat heart disease, cancer, and more. The plants or animals that give us these medicines are endangered as long as marine pollution exists. The remedies can be lost causing more people to die because of the lost medicines.
My first question is if erosion is the biggest problem to ecosystems. I learned that (at least for Hurricane Matthew) erosion was one of the main problems. Another question I have is whether deep ocean creatures are affected by hurricanes. Deep sea creatures that are territorial or are slow-swimmers are guaranteed to be dead but some creatures can swim away. The final question I have is: How are deep sea creatures affected by hurricanes?
While researching about how pollution affects sea turtles, we faced some issues on finding different types of pollution. As most people know, the plastic waste that is being dumped into the oceans and onto the beaches is becoming a main food source for sea turtles. When sea turtles see this trash, they consume the plastic causing death or severe sickness which has caused this species to become endangered. They also get tangled with the plastic in the ocean restricting them from normal movement and function. During our research, we found that there are more types of pollution affecting sea turtles than just plastic waste in the ocean.
They can consume up to one liter per day, some of the particles that are consumed are used for food but they mainly eat plankton. The other particles are combined with mucus,other matters which are deposited on the floor of the lake since they are useless to the Zebra Mussels. In this research we will be talking about how the Zebra Mussels Impacted the Great Lakes, and what the effects were and if they were positive or a negative effect. Results: 300-400 words Invasive species has always been documented to have negative harm to the environment but Zebra Mussels are invasive species that have a negative harm and also a positive effect to the environment. First we will be talking about the negative effect.
Ocean acidification is affecting marine life immensely. When our oceans keep acidifying it causes carbonate ions to be less plentiful and these ions are an important part for marine life such as oysters, clams, sea urchins, and corals to get there structures built and maintained such as their shells and coral skeletons(1). Ocean acidification can also affect some fish 's ability to detect predators putting them at a greater risk and causing the entire food web to be in danger(1). The organisms that are having the most trouble adapting to rising acidity is corals because they produce calcium carbonate to make their rocky outer layer that forms coral reefs(2). Coral reefs are the beautiful ecosystems that are booming with life but since the acidity has been rising and so has the overall temperature of the ocean the coral has been bleaching and has not been able to grow well or even stay alive(2).
Coral reef systems in the Caribbean are presently stressed due to coral bleaching, overfishing, global climate change, and disruptive algal growth (Wilkinson and Souter 2008). The addition of a piscivorous, predatory invasive species, such as lionfish, will cause permanent damage to that ecosystem. Lionfish have caused a reduction in forage fish biomass, an increase in algal growth due to their removal of herbivorous fish, and an increase in competition with native fish (Morris et al. 2009). Lionfish have few, if any, natural predators due to the presence of venomous dorsal, ventral and anal spines (Halstead et al.
Bleaching occurs when corals are exposed to water containing toxins, which cause coral reefs to lose their color and also leave them susceptible to death and disease (Pierre-Louis). One of the main culprits? Sunscreen. Thousands of tons of sunscreen wash off human bodies and into the ocean every year, and with “90% of snorkeling and diving
Question 1 Overfishing which occurs witch occurs when more fish are caught than the population can replace through natural reproduction. This has serious consequences that can affect not only the balance of life in the oceans but also the social and economic well-being of populations who depend on fish for their way of life. Overfishing in Freshwater Fishing is a crucial source of livelihood in developing nations where they can mostly fish inland and also as a main source of food that provided protein. Overfishing has lead to some freshwater fish to become extinct especially those that are found close to the surface of the water that are large and can be easily captured. The Mekong giant catfish, which is possibly the world’s largest freshwater fish, is seriously threatened by overfishing.
Since the shark fins are second most valuable illegal trade, after drugs , the hunting is done around the world and the fins are sent to China and other countries where the Asian traditions exist. Tens of millions of sharks are every year facing a slow death because of finning. The shark is caught and they remove the fins and then throw it back into the ocean – still alive. The death is often in the end caused by starvation, being eaten by other fish or drowning since they can no longer be in constant movement and therefor not extract oxygen from the water. This long tradition has now led to some shark populations being declined to up to 98% in the last fifteen
In 2010 an estimated sixteen sperm whales have been killed from gill nets (Kirby). Gill nets are mile-long nets set up overnight to catch fish. Any sea animal that encounters a gill net typically gets tangled. The purpose of the gill net is to catch the fish by their gills, but not having gills does not ensure the animal’s safety. The act of whaling is when whales are being hunted and then killed.
