You have to admit that there's something about holidays that has us Americans celebrating with reckless abandon, with little or no thought to our health, our personal safety, or how our environment is affected. For example, during the time from Thanksgiving to New Year's Day each year, fires injure over 1,600 Americans and kill 400 more.
...Charcoal/Wood grills may release twice as much carbon as a gas grill if you use charcoal briquettes (which usually contain additives such as sodium nitrate) and lighter fluid. When burned together, they contribute to ground-level ozone which is created by chemical reactions between oxides of nitrogen and volatile organic compounds. Breathing ozone can trigger several health problems including reduced lung function and inflammation of the lungs.
Tip: Use natural wood lump charcoal and a charcoal chimney starter (instead of lighter fluid) instead. Big Green Egg Organic Lump Charcoal meets EPA environmental guidelines and is CE certified in the European Union.
Gas Grills use propane, a by-product of natural gas processing and petroleum refining. Propane is a non-toxic, clean burning fuel and is not considered to be a greenhouse gas. Although propane is a clean burning fuel, petroleum isn’t. Both petroleum and natural gas are non-renewable resources.
