If you could change one global problem (climate change, poverty, education, etc.), which would you choose and why?

I want to choose the climate change problem.
Because this problem is more closer than others for me = affects me directly.
I suffer from climate change during the summer, so I can't turn off the air conditioner all the time.
I especially experience strong heat these days.
My pet "Hodoo" have to being = has to be at home when I work at the shcool, so I can't take care of Hodoo.
(Hodoo means a walnut because Hodoo is a brown-haired poodle.)
I am really worried about Hodoo because Hodoo is 10 years old.
That's why I turn on the air conditioner for Hodoo although I am not home.
I am scared about = of electric charges every month, but I can't do anything.
So I wish that climate change is = were solved.
Other problems including povety, education, etc., are also very important things to solve quickly.

Thank you for reading. Happy Tuesday. See you tomorrow!

I want to focus on the issue of climate change because it affects me directly. During the summer, the heat becomes unbearable, and I find it difficult to turn off the air conditioner for long periods. Lately, I have been experiencing particularly high temperatures. I have a pet named Hodoo, which means "walnut" in Korean, and he is a 10-year-old brown-haired poodle. When I'm at school, Hodoo has to stay home alone, and I worry about him in this heat. To ensure his comfort, I keep the air conditioner running, even when I'm not there. Although I am concerned about the rising electric bills each month, I feel I have no other choice. I genuinely wish for a solution to climate change, as it impacts not only me but many others as well. I acknowledge that other issues, such as poverty and education, are also extremely important and need urgent attention.
