Mr Mnguni fervently maintained that many power stations and the international integrated energy and chemicals company Sasol's well as coal mining and steel manufacturing companies exert negative impact on the nation's air quality, especially in the Highveld. Pollution from these industries severely impact the natural environment, water and the coal dust problem in the area impinges on human health. Land contamination in the area leads to fish and crocodile death, with equally negative impacts on tourism and agriculture. Similarly, abandoned mines burn hampering visibility and adding to the already stressed air quality. These burning sinkholes pose a serious health danger to the local inhabitants who as well as the livestock also run the risk of falling into some of those disused, uncovered sinkholes. Indoor air pollution due to indoor burning of coal poses another significant risk to human health in the area. Mr Mnguni wanted polluters to pay for their health and wondered as for whom Eskom produces electricity when the very people who live in the vicinity of power stations in the Highveld do not have access to electricity.
