Oceans around the world are being exposed to devastating destruction due to anthropogenic threats. Ecosystems commonly struggle to find stability, faced with overfishing, increasing sea temperatures and more. As key species struggle to cope with these factors, biodiversity finds itself susceptible to more primitive species groups such as jellyfish.

There are many trophic levels by which, when threatened, provide space for jellyfish blooms to infiltrate. Jellyfish thrive when oceans experience the following:

• A collapse of small fish that live closer to the sea surface, such as sardines or anchovies. These are species that feed on jellyfish and when their populations decrease, predation pressures on jellyfish plummet. Impacts are later amplified as jellyfish numbers begin to increase, remaining individuals of fish populations are often out competed for resources of zooplankton.
• Overfishing. As fish stocks are depleted due to human action, jellyfish populations increase. This initial action perpetuates the permanent removal of commercial fish from our oceans. Jellyfish prey upon the eggs and larvae of fish species, making it impossible for populations to not fall inferior to the already increasing number of jellyfish. 
• Destructive fishing practices. Trawling and other methods of fishing that damage the seabed and all of its inhabitants, create optimal conditions for jellyfish. By removing all predators while simultaneously leaving behind a rocky damaged habitat, jellyfish are able to outcompete all remaining life.
