The pellets have absolutely zero nutritional value and can not provide vital nutrients to sustain life. Since they got full from them they will not feel the need to eat for many days and will begin to feel weak from malnourishment and have trouble catching actual prey. Trash is not the only thing harming the wildlife. Another thing causing harm are chemicals. PCBs, a type of chemical in coolants, are almost completely harmless to fish, but when a bird eats a fish that has PCBs in them it will affect the strength of their eggs (Wroble 47).
Ecosystem effects Oyster hatchery in Grand Isle, Louisiana Clean up efforts have included unprecedented amounts of chemical dispersants, which are used to break up oil slicks. Although detailed effects of the chemical dispersants on wildlife and ecosystems are not well studied, the chemicals used are toxic to a variety of organisms, and they have never been previously used on this wide a scale. Because dispersants break oil up into tiny droplets, marine biologists fear that fish larvae, zooplankton and filter feeders (such as oysters), will be at risk from eating the large quantities of “non-visible” oil. Chemical dispersants are likely to impact deep-water animals downstream of the well. Oil will likely reduce the amount and health of all
The definition of over fishing is to deplete the number of fish in a body of water by too much fishing. Overfishing is very harmful to the ecosystem, taking a species close to extinction or completely extinct. As a species gets close to extinction it can be very hard to restore them back to sustainability. Even closing the fishing game for that species is not enough for a species to comeback from overfishing. Both recreational and commercial fishing have a huge impact on overfishing, by keeping under sized fish and other aquatic life.
He compares the mass extinction of various animals 65 million years ago (Glavin, 2013, p. 167) to the depletion of big fish in the sea. This presents a false analogy fallacy (Henderson, 2013, p. 52), as the extinction of dinosaurs and near disappearance of cod have very little in common, and appears to exaggerate the situation regarding the exhausting populations of fish. Furthermore, the article later goes on to discuss sustainability in fisheries (Glavin, 2013, p. 168-169), veering off the topic of defending seal hunting. The author makes references to how the Marine Stewardship Council and their "eco-label" are forcing fisheries to take up more sustainable practices (Glavin, 2013, p. 168-169). This information appears to be encouraging the reader not to boycott seafood because the seafood is becoming more and more sustainable.
We have never had a refugee crisis involving such a large amount of people. If the situation gets worse enough, thousands, if not millions could die. Other than causing possible human death or harm, increased ocean levels will put more strain on the world’s agricultural systems since many farmlands will be contaminated with salt water. Also, rising ocean levels will lower land and water biodiversity. Imagine a world with no penguins, polar bears, or even predatory fish.
Everyone has 5 cents to spare, but can they spare a life? Plastic is terrible for the environment and should be banned because of how it affects living things it takes years to go away, and it isn’t goods for the environment. Ocean creatures and our lives are at risk if we keep polluting oceans with plastic. In 2012 there was a whale found dead on the shore.
However, its size can be estimated to be between 270,000 square miles to over 5,800,000 square miles, meaning it is somewhere between the size of Texas to 8% of the Pacific Ocean. However, it is not very dense with 4 debris particles per cubic meter, which allows for satellite images or researchers on boats to aid our understanding of the Patch. As the Great Pacific Garbage Patch is so large, it naturally affects many living things: for example, the plastic waste we discard annually that ends up in the Patch can kill over 1,00,000 sea creatures according to a 2015 UC Santa Barbara study. Since the Patch is at the center of the North Pacific Gyre, it affects a plethora of different marine animals, ending up in their stomachs and poisoning their children as the plastics are long-lasting and can absorb toxic pollutants such as DDT, PAHs and PCBs. The consumption of these plastics can affect the entire food chain, poisoning the jellyfish who eat them, the fish who prey upon them, their prey, and so on.
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
“Coral reefs are biological assemblages adapted to waters with low nutrient content, and the addition of nutrients favours species that disrupt the balance of the reef communities” ( The International Coral Reef Initiative). With all of the pollution there is not any clean water for the reefs to thrive; the
It is estimated that pH will continue to drop till 0.3 to 0.4 by 2100. (Jackson 2010) BIOLOGICAL IMPACTS OF OCEAN ACIDIFICATION: Ocean acidification has many harmful impacts on living organisms. Ocean acicdifcation changes the ocean chemistry and this can disrupt the entire marine food web. It affects the life of organisms inside the water in a variety of ways. Few impacts of ocean acidification of different organisms are discussed briefly below.
