1. Environment Issues Being of International Importance
It has been well recognised that environment issues like global warming and ozone depletion, acid rain, marine pollution and biodiversity are not merely national issues but are global issues and hence must be tackled with international efforts and cooperation.
2. Explosively Increase in Pollution
