A visit to the Royal Ontario Museum

I went to the Royal Ontario Museum on the 28^th October. The ‘tour guide’ in the museum told us a lot of the phenomenon of the population dynamics happening in this world. One of the most remarkable incidents is because of the effect of global warming, the average water temperature increases which lead to the massive breeding of the giant jellyfish in the sea. To us human beings, this is not a very good sign as jellyfish would sting us with their tentacles. Once there were some fishermen in Japan, who threw their nets into the sea and instead of catching fish, they caught a huge amount of giant jellyfish, their weight even exceed the capacity of the boat and the boat turned upside down. Some of the people suggest that in order to eradicate these jellyfish, they should build a net full with steel spikes and tear all of the jellyfish apart, however, it turned out that this is a very bad solution as these giant jellyfish breed a lot when they feel anxious, this causes a lot of their eggs to land on the seabed. The food chain is interconnected, there is always a reason why such an animal exists in this world, disrupting the habitat would surely lead to unimaginable consequences, therefore we should monitor frequently the effect of the activities on the environment.
