ROM: Attack of the Jellys!!!!

So long time ago, my bio class got to go on a field trip to the Royal Ontario Museum! I was very excited because that was the only field trip I will have this semester. However, my excitement has been crushed soon after we arrived at ROM. And that is because a very nice gentleman, who is an excellent storyteller, guided us through everything that is wrong with our ecosystem. There were many species that were bound to be extinct, were going to be extinct but sustained their population or have already been extinct all thanks to human activities. Among many tragic stories, I have decided to talk about Jellyfish! *Jellyfish are not actually fish so technically they are just Jellys* 


There are many speculations to what had happened to the jellys but one thing is for certain, jellys are taking over the ocean! Some theories to this phenomena are over-fishing, and rising oceanic temperature from global warming. The fish and jelly populations are very intertwined with each other. The fish and jelly prey on the same kinds so when fish are out of the picture, jelly had more food to themselves. Also, as the population of jellys increase, more fish eggs are eaten by the jelly. Also, the rising temperature produce the perfect breeding ground for the jelly. It is a huge problem for food supply for humans because on one hand, the useful resources are decreasing and on the other, mesh of problems to clean up are increasing. 

Some scientists say that the fear of these Jellyfish are overblown. The jellyfish blooms have happened before and it is part of the cyclical increase. Eventually, the population of jellys will oversize the available food supply and lead to a crash. 

Whatever the case may be, the over-fishing and rising temperature are definitely not helping the marine ecosystem.
