Zoltan Berki, 28, plays with his daughters in Sajonemeti, Hungary, September 13, 2020. Berki usually wakes up before dawn, as his five small children sleep next door, to feed the old iron furnace that stands in a wall cavity to warm up both rooms. This is the only part of his house that he can afford to heat during winter. "Firewood is expensive," Berki said one recent afternoon, as his family played around him, crammed into one small room. "Either I buy wood or food. So I go to the forest, or the junkyard, and if we find plastic or rubber we burn that. "But not during the day or the neighbours can see, and you can also smell it. We throw the rubber and the plastic bottles and such things on at night." REUTERS/Marton Monus SEARCH "MONUS POLLUTION" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
