The problem is that burning it blows carbon-oxygen atoms out tailpipes, where they pollute, and ultimately cause atmospheric damage. You can't tell me all of that soot is a good thing.
Damn straight I can.
The process of life requires pollution. Not to be graphic, but life literally sustains itself by converting the environment (air, water, food) into pollution. On top of that, creating our comforts and pleasures require additional pollution.
The countries that pollute the least in the world are the countries with the shortest lifespans and the harshest living conditions.
The trick is not to eliminate pollution, but just remove it so it doesn't harm people. We are already quite effective at that. (And when we aren't it's usually due to a lack of property rights)
The longer and more comfortable a human life is, the more pollution is required.
The only way to eliminate pollution is to eliminate life itself.
