摘要：It was 1987. The Soviet Union launched the Mir Space Station, the world population reached five billion, Oscar Arias Sanchez won the Nobel Peace Prize and Paul Simon’s ‘Graceland’ was named record of the year. But perhaps the key event occurred in Canada, when the world’s nations agreed to the Montreal Protocol to repair and protect the Earth’s protective ozone layer.
The treaty is perhaps the single most successful international environmental agreement ever made. It generates science and deploys funds to assist developing countries to phase out ozone damaging chemicals, like chlorofluorocarbons (CFCs) and halons. But its impact stretches beyond safeguarding public health from excessive ultra violet rays from the sun.
