Mass moovement: Demonstrations against low milk prices and demands for aid have been going on for over a month in Europe, culminating yesterday when protesters invaded Brussels. Above, Belgian dairy farmers, many of whom brought their cows, protest low milk prices outside European Commission headquarters on Sept. 7. Organizers say milk prices are less than 75 percent of production costs and will only get worse if the European Union's proposal to eliminate milk quotas by 2015 comes to fruition.
