Landfill waste results in air pollution as A) garbage decomposes and releases methane. When "biodegradable" products such as food or paper waste begin to decompose they release methane into the atmosphere which is a pollutant and also a major greenhouse gas. This is an unintended side affect of using certain products that are believed to be environmentally friendly.
