In 1971, 93 per cent of voters back the inclusion of a new article on environmental protection in the Swiss Constitution. Its aim is to protect human beings and the natural environment against damage. The overwhelming support reflects a new awareness of ecological issues: many view the mass motorisation of road traffic as a negative development. As a result, major railway projects stand a good chance of gaining majority approval. The successful NRLA campaigns of the 1990s also focus on forest dieback, protection of the Alpine environment, and shifting traffic from road to rail.
