Coal is the dirtiest of the dirty fossil fuels.
Coal tar is a synthetic form of tar that is mixed with coal and used to soften the tar in mines and roads.
Sugar is the liquid form of coal tar, and is added to make the tar lighter.
Coal can be used to make up a lot of your home’s electrical and plumbing system.
It is the second most abundant fossil fuel in the world after oil, but it accounts for only about 2 percent of global emissions.
So how does coal affect your health?
It’s not clear, but the science is complicated.
It’s hard to say how much damage coal can do.
There is some research that suggests coal is more harmful to health than some of the other fuels we use, including natural gas and ethanol.
But the research is preliminary, and it’s possible that a particular coal tar compound could have a protective effect.
Researchers have also linked coal tar to lung disease and heart disease, but not enough to warrant a specific policy to regulate.
But coal tar is also the main component in some types of natural gas, and this may also contribute to the increased health problems that coal causes.
It turns out that the coal tar compounds we see in tar sands can also be found in sugar, a major component of sugar cane.
So the next time you’re looking at a sugar cane field, you may want to consider whether you should buy a bag of coal.
