The theme of our poster is the earth in the glass. From the whole poster we can see the element of carbon dioxide, and we use oxygen to represent a globe. To illustrate humanity if it continues to destroy the earth, the greenhouse effect will be more and more serious, then one day the water in the glass will completely cover the entire earth, which means that the earth will no longer have lands, and the water in the glass is turbid. That means, the damage that the human race has caused to the Earth will be sent back thousands of times to humanity in the form of disaster. And the “2” replaced by a broken satellites, it also proves that If humanity continues to destroy the earth, one day human civilization will disappear. Therefore, we appeal that you should care more about our planet now and make tomorrow no longer dark.
