WCAAD student Yuki Gu, 17 years old：The Earth in the painting is no longer habitable due to years of pollution and human ruin. The planet's surface is littered with waste and construction debris that could collapse at any time. Many humans have migrated to other planets due to the harsh environment and scarcity of resources. Small number of human, however, have chosen to remain in the hope of assisting the planet's recovery. Please do not wait for the situation to worsen before acting. Please begin preserving our world immediately.
