To the future younger generations:
I am writing this letter because I hope you are living in a better life, a better environment. Now, this is 2017. We are experiencing the climate change. The global warming is happening. The temperature is increasing, the sea level is rising, and the sky is getting dirty. Even though we are trying to solve this problem, we still have a long way to go. I hope when you read this letter, people have solved this problem. Maybe you are using the environment friendly resources, and enjoy the clean air.
