I want to know the answer to the following question:
What sort of issues were Zenlenyi Svit and Noosfera concerned with?
All the background I'm provided with is that "On November 13, 1988, approximately 10,000 people attended an officially sanctioned meeting organized by the cultural heritage organization Spadschyna, the Kyiv University student club Hromada, and the environmental groups Zelenyi Svit ("Green World") and Noosfera, to focus on ecological issues.". Is that enough to answer the question?
Answer: yes
