The ocean issues : is it getting better?? Misaki Alpha Yusuke

 Is the state of our ocean getting better?. We are talking about plastic pollution in the ocean, the population of sea animals, and how catching fish affects the species.


This graph shows that the number of microplastic in the eastern tropical pacific from 2008 to 2020 has increased every year and continues to go up from 2020, resulting in affecting marine life.



This graph illustrates that the number of marine animals between 1970 and 2012.

It decreased dramatically from in 1975 to in 1990 by just under 50%. Since 1990, the number of animals in the ocean slightly fluctuated but in 2012, it moderately went down. According to graph, the status of ocean is getting worse. Although we could not get information why marine populations have declined, it is clearly show decrease the number of marine animals is terrible result. I think it is linked to the number of plastic or rubbish which human made. People began to use reusable bag instead of plastic one and other product also shift more eco-friendly so the more careful people think about environmental issue including ocean problem, the better condition will be in the future but otherwise it will still get worse.                                                                                                                                                                                                                                                                                                            




These graph indicate the number of marine species in 3 oceans.

From this graph, we can notice that the relation between the number of the fish and the number of the fish caught by people.

The data of these graphs describes the period between 1950 and 2000.

As we watch this graph, we can notice that  the connection between “species density” and “catch” is like an inverse proportion.

Furthermore, as a whole, “species density” is decreasing gradually these days.

I feel like that it means it’ll be difficult little by little to get natural fish. I prefer natural fish to farming fish, so I pray that it’ll be improved in the future.

Needless to say, according to this graph, the condition of the ocean is getting worse gradually.

      Hello my name is Athit Komin, my nickname is Alpha, people usually call me by my nickname. I lived in Bangkok which is the capital city of Thailand. Early this year, I just graduated from high school and I will be going to the university in Thailand this August. When talking about my favorite subject I like the most in high school would definitely be Physical Education because I do not have to think much during the class and I also get to play with my friends in this subject. During the study in Dunedin I am staying in Kenmure with Pooley’s family. I used to come to Dunedin for high school in Yr9 and Yr10, so I am very familiar with this place and the best part of Dunedin is the view of the city and  the beach. Coming back to Dunedin this time is to study an English course at the Otago University, the reason I choose this course is to improve my writing skills and also reading skills, which will help me in the future with my career. Furthermore, I am an easygoing and introverte

As I said, I like music. So, of course I like to listen to music. Also, I like to play musical instruments. I can play the flute and piano. I brought my flute to New Zealand and practice the flute sometimes. In addition, I love cats. When I was in Japan, I didn't have cats. But now I have two cats and they make me relaxed. No cats, No life. On the other hand, I don’t like to study. And I’m not good at keeping

And I live in Mosgiel with my host family who are host mother, father and one dog too now.       I think people who live in Dunedin is very friendly and kindly. People who do not know tell me about food taste like “This is so good” or “It’s nor good taste “ when I was shopping in supermarket with my host family. And I think they have a lot of talking when they have food with them family and friends comped with Japanese people.        My favorite time is eating, watching movies, listening to music, going for a walk and sleeping time. They make me happy and relax. However I often get too lazy if I have free time so I think it is not good point about me.
