The short message about Earth Hour aims to promote environmental protection.

It may not matter if a person turns off the lights for an hour: but if everyone turns off the lights for an hour, a river will accumulate. Although it is an hour, it reduces a lot of carbon emissions; Starting from every little thing, we can make the sky brighter, the air fresher and our living environment better! Therefore, we hope that through global public forces, we can actively deal with environmental problems, save energy, build a harmonious society and a harmonious campus, and create a beautiful home for mankind. Dear friends, let's act for Earth Hour! This is not only the cry of the earth, but also the cry of each of us.

It can be divided into two parts, and each part is good.
