> affecting the ability of people to support themselves Well, that depends. Is it subsistence farming? Or is it for biofuel? Biofuels may, during combustion, cause fewer emissions, but add in the change in land use (with the attendant fertilizing regimen, etc.) and the reduction in carbon sequestration from removing trees... That causes deforestation for biofuel to be worse than just burning fossil fuels in the first place. Burning things isn't the way out, no matter how neatly those things burn. Nuclear power (whose waste products arguably are vastly easier to contain than burning anything), solar power, geothermal power (the benefits of nuclear power without the pesky reactors) ... Even wind/hydroelectric power generation are, kWh-to-kWh, less damaging to our climate overall.
