Raw Video : Farmers in Belgium have dumped 3 million litres of fresh milk right back onto the green pastures that cows graze on to underscore that European producers can't make a living from current rock-bottom milk prices.

Milk farmers' co-operatives said Wednesday world prices had gone so low that they had to sell at half the production cost, leaving ever more farmers unable to pay their bills.

To highlight their desperation, about 300 tractors and milk containers sprayed green fields in southern Belgium, representing the loss of a day's worth of milk production in that part of the country.
