‘ UG production has the potential to generate considerable greenhouse gas emissions, can strain water resources, result in water contamination, may have negative impacts on public health (through air and soil contaminants; noise pollution), on biodiversity (through land clearance), food supply (through competition for land and water resources), as well as on soil (pollution, crusting).’  – UNEP Global Environmental Alert System 2012
