ZURICH (Reuters) - Swiss environmentalists, tapping into unease about population levels in their landlocked nation at the heart of Europe, on Friday presented the government with 120,000 signatures to force a referendum on limiting immigration.
Under the Swiss system of direct democracy, 100,000 signatures need to be collected to put a cause to a national vote. Referenda take place up to four times a year after the government sets dates for the voting.
Ecopop, an organization which campaigns on environmental and population issues, on Friday handed in boxes containing the signatures supporting their initiative "Stop overpopulation to safeguard natural resources".
