Candles! Should we lit candles?

India in the last couple of years have seen several candle light protests. Protesters were seen holding candle while marching to protest during many recent protest marches. I do not know the ramification or the success rate of such protests and if those protests have yielded any positive results. I am though very sure that those protest marches were never environment friendly, as modern day candles are very rude to the environment. Given the fact that modern candles are prepared from not properly refined paraffin (a petroleum product) which makes it a major cause of environmental pollution. The smoke from the wick of the candles along with unburned hydro carbons can cause terrible disturbances with our health. The risk becomes manifold as candles are generally lit indoors and this particular fact multiplies the health hazards from burning candles.....
