The poster starts with panda, hoping to remind us not to blindly exploit and destroy ecological resources, and reminds us that we share the same future with animals. Designers use Gestalt psychology to get people to build perfectionism, and the designers use black and white, the color of the panda, to attract us, and we will notice the scenes of destruction. The people waving shovels and then changing into eyes, and bulldozers changing into noses and mouths come up to us. Designers skillfully use silhouette to recombine the elements, and simple design language is more attractive.
