Rising Energy Costs Drive Up Forest Thievery .
The problem has been compounded this winter by rising energy costs. The Germany's Renters Association estimates the heating costs will go up 22 percent this winter alone. A side effect is an increasing number of people turning to wood-burning stoves for warmth. Germans bought 400,000 such stoves in 2011, the German magazine FOCUS reported this week. It marks the continuation of a trend: The number of Germans buying heating devices that burn wood and coal has grown steadily since 2005, according to consumer research company GfK Group.
