August 24th, Amsterdam. A peaceful protest took place this Thursday at the Dam in Amsterdam. During the last weeks, a series of barn fires have happened around The Netherlands, in one of them, 20,000 pigs died in a fire at a factory farm near the Gelderland village of Erichem, in what was the second major farm fire this month. Animal welfare lobby group "Wakker Dier" says never before have so many pigs died in a single blaze. The organisation keeps a running tally of factory farm fire deaths which shows nearly 200,000 animals have been killed so far this year. That means 2017 is likely to be the worst year for factory farm fires since 2011, when 319,000 pigs and chickens were killed.
