Underground Coal Fires
Coal burning deep underground in China, India and Indonesia is threatening the environment andhuman life, scientists have warned. These large-scale __________(51) blazes cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can __________(52) ignite forest fires, a panel of scientists told the annual meeting of the American Association for the Advancement of Science in Denver.
