Brown coal mining limits in North Bohemia of mining operations whole villages, towns and even cities (Most) were demolished to extract the coal that lay beneath; their inhabitants were rehoused in large-scale new prefabricated panelled apartment buildings. The low quality technology used for large-scale burning of brown coal led to a sharp increase in the content of harmful sulfur dioxide and aerosols in the atmosphere. The result was wholesale damage to the environment (such as the die-back of the forests in the Ore Mountains from acid rain) and human health. In view of the unsustainable situation, the first post-communist Czechoslovak government decided to resolve the situation by
Environmental impact of the coal industry This is due to the relaxation of pressure and fracturing of the strata during mining activity, which gives rise to safety concerns for the coal miners if not managed properly. The buildup of pressure in the strata can lead to explosions during (or after) the mining process if prevention methods, such as "methane draining", are not taken. In 2008 James E. Hansen and Pushker Kharecha published a peer-reviewed scientific study analyzing the effect of a coal phase-out on atmospheric CO levels. Their baseline mitigation scenario was a phaseout of global coal emissions by 2050. Under the "Business as Usual" scenario,
