Threats to the environment recognize no boundaries. Their urgent nature requires strengthened international cooperation among all countries. Significant progress has been achieved in a number of environmental areas. Montreal Protocol on Substances that Deplete the Ozone Layer is a milestone. All countries are encouraged to sign and ratify it.
Further action is needed.
Global climate change, air, sea and fresh water pollution, acid rain, hazardous substances, deforestation, and endangered species require priority attention. It is, therefore, timely that negotiations on a protocol on emissions of nitrogen oxides within the framework of the Geneva Convention on Longrange Transboundary Air Pollution be pursued energetically. We also recognize the potential impact of agriculture on the environment, whether negative through overintensive use of resources or positive in preventing desertification. We welcome the Conference on the Changing Atmosphere to be held in Toronto next week.
