How the Great Pacific Garbage Patch is Destroying the Oceans and the Future for Marine Life

# data[].attributes.body
The Great Pacific Garbage Patch is twice the size of Texas and is in between Hawaii and California. In fact, 70% of the debris sinks to the ocean floor and 80% of the trash in this patch comes from land-based activities in North America and Asia. This has caused a catastrophe for wildlife as ingesting plastic causes starvation or ruptured organs and getting caught in trash can cause wounds, infections, and starvation.

Images Showing the Impact of Plastic on Ocean Animals

# data[].attributes.body
As well as giving images of the effects of marine pollution, this article also gives information about what ingesting pollution does to animals. After ingestion, the plastic can release plasticizers which are linked to cancer. In addition, microplastics are consumed by smaller organisms such as plankton and mussels, which then affects the food chain as they are consumed. Microplastics have two main sources, which are in nurdles, small pellets of plastic, and secondary microplastics, small pieces of plastic that degraded from larger pieces.

How Does Ocean Pollution Affect Marine Life?

# data[].attributes.body
This article mainly describes the problem of plastic pollution in the ocean as there is an estimated 15-51 trillion pieces in the sea. The amount of plastic impacts the life of marine animals because it becomes part of the ecosystem and the animals ingest it or get tangled in it. The website specifically describes the perils of sea turtles, hawaiian monk seals, marine mammals, and seabirds.

How Plastic Pollution is Affecting the Ocean Wildlife

# data[].attributes.body
This website describes the effect of plastic pollution on marine life and gives harrowing statistics. It is proposed that over 700 species can go extinct and that at least 267 species have already been affected by pollution. In addition, one in three marine mammals have been caught in marine litter and over 90% of seabirds have plastic in their stomachs. This even effects deep sea creatures as polyethylene, polyesters, and micro plastics have been found in these organisms.

Effects of Ocean Pollution on Marine Life

# data[].attributes.body
This website explores the various pollutants and effects on ocean life. It examines the effects of oil on the ocean, the coral reef impact, toxic materials, and trash and other debris. The most interesting part is the statistic on the effects of ocean pollution. This includes recent statistics of how many species encounter marine debris, how much debris was found in species, and how many species had plastic in their stomachs.

The Center for Biological Diversity makes the prediction that plastic will outweigh all fish in the sea by 2050 due to the negative impacts on marine life. They even make the prediction tangible by having a map where the reader can move the Great Pacific Garbage Patch over the United States to see how large it is. The article also describe the toll on wildlife which includes intestinal injury and death of organism, the effect on the food chain, and the endangerment and mortality of several species.

This website discusses the causes and effects of ocean pollution. Ocean pollution can be caused by sewage, toxic chemicals from industries, land runoff, large scale oil spills, ocean mining, and littering. This affects the marine ecosystem by disrupting marine life through oil spills, disturbing the cycle of coral reefs, depleting oxygen, causing failure in the marine life's reproductive system, affecting the food chain through the consumption of micro plastics and chemicals, and affecting human health by causing cancer, birth defects, or health problems.

The National Resources Defense Council describes ocean acidification, trash in the ocean, ocean noise, and offshore drilling. Ocean acidification impacts the ecosystem as the pH of the surface waters change which cause the carbonate levels to go down and threatens the survival of mussels, clams, coral, and oysters as well as bleaching coral reefs and affecting the shellfish industry. The majority of trash in the ocean is non degradable plastic and chemical discharges, which affect marine life. In addition, the ocean tends to have sound waves move farther and faster than in air, so noise pollution alters foraging, mating, habitats, and other vital behaviors of organisms. Offshore drilling emits toxic by-products and creates irreversible damage to ecosystems through spills.

The National Oceanic and Atmospheric Administration explains the impact of ocean pollution on nutrients, algal blooms, and seafood and the problems of marine debris. They first distinguish non-point source pollution and point source pollution. The article then discusses algal blooms caused by excessive concentrations of nutrients and how that can be a pollutant by consuming oxygen and causing hypoxic or dead zones. Marine debris is also a problem as it kills marine life, obstructs navigation, and is a threat to human health. The author also talks about the impact on seafood from the heavy metals and contaminants, which then work its way into our food system (monitored by Mussel Watch and FishWatch).

This website gives an overview of pollution such as the definition, types, and sources. It gives the two categories of sources of pollution which are point and non-point. A point source is a single, identifiable source, while a non-point source is a scattered and hard to identify source of pollution. The effects of pollution are also discussed in terms of whether the pollution is chemical in nature, the concentration, and if it is degradable.

National Geographic gives an in depth look at the different types of pollution such as light, noise, chemical, and plastic and describes how it affects the ecosystem and marine life. Chemical pollution can cause massive blooms of algae, can climb high into the food webs, and human usage can end up in aquatic food webs. Light pollution disrupts circadian rhythms in marine which affect timing of migration, reproducing, and feeding. Noise pollution disrupts underwater communication between organisms which disturbs migration, hunting, and reproduction. Plastic pollution affects marine organisms as plastic products are often consumed, which causes them to perish.

How Does Ocean Pollution Affects Humans?

# data[].attributes.body
This source has a video and an infographic about how marine pollution affects humans. The video shows an aluminum can swallowed by a fish, which then raises the question of how does this affect the food chain including humans. The infographic explains how different forms of pollution affect humans and their body. The author also has an anecdote about their diving trip in the Similan Islands where there is supposed to be diverse life, but they found only trash and little to no fish. The website ends with ideas for what the reader can do to reduce their waste.
