𝗟𝗲𝘁 𝘄𝗮𝘁𝗲𝗿 𝘀𝗽𝗲𝗮𝗸! 𝗜𝘁 𝗵𝗮𝘀 𝗶𝘁𝘀 𝗼𝘄𝗻 𝘀𝘁𝗼𝗿𝘆. The theme of our 50th Anniversary On-the-Spot Poster Making Contest highlights the reality of how society often ignores or even silence the voice of water in the pursuit of economic development. True insight, sustainable design, and sound decision-making can only be achieved when we choose to listen to water. This collection of artworks bridges science and art, reflecting both the challenges we face and the hope for a better, more sustainable future.
