There is only one life, and there is only one earth. The earth is our great mother, what should we do for her? Between the sky and the land, we enjoy the fresh air; between the North Pole and the South Pole, we hold the flowers of love in our hands. Give every pair of eyes a bright light. Give every friend in the river clear water, give every animal fresh food, and let every seed grow steadily. Let the representatives of the animal kingdom take to the rostrum of the United Nations; let the green tung trees tell the story of the past and the future. Turn the battlefield into a green grassland, let the cannonballs shoot out beautiful flowers, put the painter's works on display in the museum, and invite pine trees and swans to visit the city. Blue eyes and black eyes express the same hope; the children will shoulder the sacred responsibility and turn the earth into a beautiful paradise on earth! There is only one earth. We bully it like this because we should protect it. Let’s see what we should do for it? Let the garbage come to your house, and let the snowflakes fall to the world again. Let the earth wear its new clothes and let the grass grow again.
