A worker looks on while standing in front of a furnace in the Temirtau steel plant in the town of Temirtau, central Kazakhstan December 7, 2009. With its chimneys towering high above the steppe of central Kazakhstan, a giant maze of rusty pipes and billowing furnaces built in the 1960s, the plant is Central Asia's biggest steel producer -- and one of its biggest polluters. The start of climate talks in Copenhagen on Monday has given new impetus to a campaign by local ecologists and production officials to tackle the problem.
