Make your own civilization and promise a word! That is, hurry! thank you

Civilization is a great learning! There are too many aspects involved! This world is a civilization, a human civilization! You have to talk about the promise of civilization. Where are you going to use it? Not hot is not right! You said no! I'll make up some for you now!

It took mankind five thousand years to reach today's civilization, and I won't let it disappear!

For the future of the earth and the happiness of future generations, I decided to save water/live a carbon-free life/protect forests. . . . . .

Protect the earth/environment/ecology/atmosphere/ozone/ocean. . . . . Have me! ! !

Protect the earth/environment. . . . On this issue, do your bit, stupid spirit, endless descendants!

I try to breathe to purify our air.

Never buy a car, we have legs!

Planting trees every year, we have hands!
