Global Warming : Is it getting better? - Yuri, Andrew, Mion

 

We expected that the global warming is getting worse. 

We would like to explan about why it is happened, what is happened by it and solutions.


                                                                https://t h.bing.com/th/id/OIP.fF8f9QiH7EYzr4qdj1Qc1wAAAA?rs=1&pid=ImgDetMain

  We already know that global warming is caused by greenhouse gases, so we looked at what causes greenhouse gases. Several reasons are given.

  The biggest reason is electricity, 30%. We predicted that's because everyone uses electricity every day. When electricity is produced, we burn carbon, including fossil fuels to power our generators. That produces a lot of carbon dioxide. Next is transport. We produce carbon dioxide by burning fossil fuels. On the other hand, the smallest causes are construction and industrial processes. The reason for building is that people need to control temperature, such as air conditioning and ventilation. These are powered by electricity. Industrial process is that when people who work in the factory make some machine and goods, a lot of energy is used which is made by burning.

As you can see, most of the reasons are related to burning things.

 

Now we are talking about the effect of global warming. The effects of global warming are very diverse.

For example, there is

  • Ocean acidification
  • Habitat destruction
  • Intensified weather events
  • Global fish stock decline
  • Glacial retreat
  • Human health problems

I want to talk about how it affects human health. Look at the graph below. Air pollution caused by global warming can lead to cardiovascular and respiratory problems. Changes in vector ecology can increase the spread of infectious diseases like malaria. If clean water and enough food are not provided, it can cause malnutrition, which can increase infant mortality rates. Extreme heat can cause heat-related illnesses and deaths among vulnerable groups. Severe weather changes can affect birth rates in the long term and lead to population decline.

This graph shows the carbon dioxide emissions per capita in representative countries. Global warming is happening year by year due to the increase of carbon dioxide in the world. So, I would talk about some solutions to decrease mounts of carbon dioxide.

1.     Reduce standby Power

2.     Review the temperature setting of the air conditioner

3.     Use LEDs

4.     Use environmentally friendly electricity

5.     Use public transportation

6.     Use eco-friendly bags

7.     Proactively buy products with simplified packaging

8.     Reduce the amount of time spent in the shower

9.     Use means of transportation with less environmental impact

10.  No food loss and reducing the percentage of meat consumption

 One person cannot make a tremendous change, but each one of us can lead to a solution y being aware of the situation and taking action.

      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.
