Have you ever thought jellyfish were bad? Imagine a swarm of jellyfish came at you. What would you do? Jellyfish are becoming a concern; they are swarming fishing nets and affecting power plant pipes. These fish have reduced the number of fish and are clogging power plant pipes. These fish pose a threat to our economy, what will we do about it?

The jellyfish has ruined fish harvesting and drastically decreased fish numbers. The jellyfish have affected the fish population and ruined the power plants. The jellyfish sting and harm the fish, so they are swarming the fish away. The jellyfish continue to clog the pipes in the power plants, so they are forced to shut down the plant.

The fish have caused many problems for fishers and for power plant workers. The fish are dangerous and are becoming the pests of the ocean. The solution to some of these problems are to use some extra precaution and smaller nets. These fish are a harmful and pesty problem for today's Economy. The workers should not be the people to worry about the jellyfish.

The major solution to this problem is to cut down on pollution. The reason for this is so the jellyfish have nothing to feed on. The reason for these swarms and clogging is because the jellyfish feed on the trash and pollution. These fish are a threat to our economy and are a danger to humans and animals. The jellyfish solution should be started immediately.

The jellyfish problem should be solved soon because if it doesn’t the jellyfish will take over. The jellyfish could continue to harm the fish and clog the power plant pipes. The problem will continue if we don’t do anything about it. Jellyfish are an example of the economy's many large problems, will this problem end the same?

I hope this is ok, i changed some wording around, changed the last paragraph, and fixed some grammatical errors. Good luck!
Remember to use whatever format your teacher requires, like MLA. :)
