In what year did the first major UN meeting on environmental issues take place?

The first major UN meeting on environmental issues took place in 1972 during the United Nations Conference on the Human Environment, held in Stockholm, Sweden. This landmark conference marked a significant moment in the global discourse on environmental protection, bringing together representatives from 113 countries to discuss problems related to environmental degradation and its impacts on human life.
