The Jellyfish Dystopia Essay -- Ecology
EarthÃ¢â¬â¢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 AtwoodÃ¢â¬â¢s A HandmaidÃ¢â¬â¢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 decr eases 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... ...er what manipulating this environment may due to the jellyfish. Unfortunately, in many cases we are improving conditions for them and as a result degrading our own situation. Works Cited Blomberg, Lindsey. "The Great Jellyfish Invasion."
