Earth’s environment is a complex construction with multiple parts that are all important to its success. Even creatures like jellyfish cannot be ignored when considering this delicate construction. As humans manipulate the environment, conditions are beginning to favor jellyfish and promote large population explosions. The effects of these large populations have a myriad of effects on humans and can be applied to ecological dynamics found in Margaret Atwood’s A Handmaid’s Tale.
The manipulation of the environment by humans is the first factor that has begun to promote the jellyfish dystopia. As humans change the environment, conditions are beginning to favor jellyfish. In an environment that largely favors them, a population explosion and accompanying jellyfish dystopia is inevitable. These population explosions are a great leap toward the jellyfish dystopia. Throughout the marine environment, humans have begun overfishing in multiple marine environments. This opens niches in the oceanic food webs. These niches, or spaces in the food webs, result from the removal of predators that would previously control the jellyfish population (Stone). In the absence of their predators, the jellyfish population is free to expand and forms blooms, or large jellyfish populations. The jellyfish themselves then prevent the native fish population from rebounding by feeding on the fish eggs (Stone). Human proceed to fish in these areas again, and the jellyfish predation decreases to a greater degree. Humans also improve conditions for jellyfish as we allow pollution levels to rise. Devices like cars are contributors to the carbon dioxide levels. As the CO2 levels rise, this also affects the oceans. They slowly are becoming more acidic and becomin...

In this entertaining, search into global fish hatcheries, New York Times writer Paul Greenberg investigates our historical connection with the ever changing ocean and the wild fish within it. In the beginning of the book Paul is telling his childhood fishing stories to his friends, that night Paul discovers that that four fish dominate the world’s seafood markets in which are salmon, tuna, cod, and bass. He tries to figure out why this is and the only logical answer he could come up with is that four epochal shifts caused theses wild fish population to diminish. History shows that four epochal shifts happen within fifteen years causing certain fish species populations to diminish. He discovers for each of the four fish why this happened to

Simply, overfishing depletes fish stocks. The consumer demand for fish has risen dramatically over the past decade or so, so much that fisheries are designing new and innovate ways to catch more fish, and at a faster rate to meet consumer demands. What fisheries do not realize, though, is that their removal of fish from the oceans is too great and far too fast for new fish stocks to be made. So, no mating is occurring, leaving the oceans emptier each day. If this rate continues, all fish in the ocean will be almost non-existent. Already, we are experiencing a major decline in fish population: "In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population. "(par.6).Overfishing brings the main consequence of decrease in the fish population. People rely on fish for survival (in some countries, fish is their only source of food), and they rely on marine life for products (goods like lipstick, petroleum jelly, make-up, etc.)

The Mnemiopsis jellyfish is growing in numbers everyday, causing power plant problems in the Sea of Japan. In my article that was used for research it states that, “The Sea of Japan is filled with jellyfish and is disturbing the ecology and clogging our power plants – Stated a local High School student” This is a fact that can’t be ignored. A plan needs to develop quickly!
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended specie. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of chain depends largely on the interaction between the predator and the prey. For example, if the larger fish are removed than its prey begins to overpopulate, due to the lack of population control. The balance in the oceans are a urgent problem, around 90% of predatory fish stocks are depleted. The ripples can extend even further to land creatures like
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.

In the 11th century, there has been overfishing in the economic regions. Starting the 14th century and through the 19th century there has been fierce discussions about overfishing. Once fishermen caught a lot of fish in that specific area, they just moved on to a different spot from there. Beginning the 21st century the overfishing crisis has turned into a global threat to the oceans.
Overfishing is one of the biggest threats to the ocean ecosystem because it not only destroys the environment that surrounds

Similarly, without corals to take in carbon dioxide, the amount of gas in the atmosphere will increase, thus affect all life negatively. Hence, it is clear that overfishing has dreadful ecological
