On 30 November, Switzerland’s voters will decide whether to pass a controversial amendment put forth by Ecopop, a group of Swiss environmentalists. The initiative calls for boosting birth control in developing countries as a way to curb immigration, which according to the group shouldn’t exceed 0.2 per cent of the Swiss population over three years. While the campaign gathered over 120,000 signatures in 2012, it now faces tough opposition from the government, the business community and trade unions, who argue the initiative is too strict.
