We must switch our energy economy away from fossil fuels and to renewable, non-greenhouse energy (and/or nuclear). This means we will no longer be burning coal. This means the coal industry will go bankrupt and no longer exist. Likewise the oil industry. Likewise the natural gas industry. Other industries will arise to replace them, employing just as many people or more, because we will still need energy. The only people that will be hurt is the large-scale stockholders of those industries, and considering they are all multimillionaires, I suspect they will survive somehow.
