Wall of remembrance and hope

Imagine you could leave a message to the world—a single phrase that would be seen by people in different countries. What would you say about the Semipalatinsk nuclear test site, its history, and its lessons for humanity?

Consider:
What is the most important lesson humanity should learn from the test site's history?
How do you feel after learning the truth about nuclear testing?
What should future generations remember?

Write a short message (1-2 sentences), indicate your place of residence, and, if desired, attach a photo of yourself.
