Green Life Proposal: Let's climb the stairs together

Classmates, have you thought that we can climb the stairs home every day? Since last year, I have not taken the elevator every day, but I climbed the stairs myself. Whether it is the fourth floor or the tenth floor, I insist on climbing up.

Do you know what benefits are you going to climb the stairs? First of all, I can exercise and strengthen my body. I have never been to the hospital since I started climbing stairs. Moreover, climbing stairs can also save electricity. I found on Baidu: "Elevator needs 1 kWh per run up and down", so that I can save at least 2 kWh per day, and save 60 kWh in one month. In that year, I can save 720 kWh.

Let's climb the stairs together and greet the arrival of the 2019 Nanjing Youth Olympic Games with green life.
