It's 2054. I'm sitting in my room, looking at the screen in front of me for a long time. A small sound breaks the quietness. It's a new message from Mia, my best friend for as long as I can remember.
"Hey, have you seen the news? The sea waters are going up faster than we thought. My family's moving north next week."
I take a deep breath (深呼吸) and answer on the screen, "Yeah, I saw it. It's like we can't stop it anymore. We're moving, too."
A new pop-up (弹出式窗口) suddenly pops up on the screen. It's about the people who have to move away from the seaside cities. People are leaving for higher places. A program shows the sea water is going up and covering all the neighborhoods. It's hard to believe that this is the world we live in now.
Last weekend, my parents sat me down for a serious talk. We were going to leave our city and move north, away from the seaside. I knew we had to keep living, but leaving everything behind made us sad.
But there was something else my dad said. He had a plan for our new home. "We can't just live," he told me. "We have to become strong and successful. We'll build new neighborhoods that are good for the Earth and won't put it in danger."
As we pack (打包) our bags, another message comes in from Mia. Her family is also planning how to build their new home. They'll plant trees with the people who live there. That gives me hope. Maybe all the families moving north will build a new future, different from the past.
The next few years will be hard, but I'm ready for difficulties. Together, we'll make the future better.
