Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Research has determined that fracking negatively affects human health and drives climate change. [2] [3] [4] Fracking fluids include proppants and other substances, which include chemicals known to be toxic, as well as unknown chemicals that may be toxic. [5] In the United States, such additives may be treated as trade secrets by companies who ...
Grazing can have positive or negative effects on rangeland health, depending on management quality, [128] and grazing can have different effects on different soils [129] and different plant communities. [130] Grazing can sometimes reduce, and other times increase, biodiversity of grassland ecosystems.

The Yale School of Public Health found that fracking has led to heightened concerns about its impact on the environment and human health due to wastewater and greenhouse gas emissions.
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
The increase in fracking from 2009 led to a drop in natural gas prices that made natural gas become more competitive with coal. This analysis estimates coal generation decreased as a result by 28%, which led to an average reduction of 4% in air pollution yielding positive health benefits.
Adverse environmental and health impacts have been reported by communities who live near areas with significant fracking activity. [28] Studies have shown that fracking may be a cause of groundwater contamination. [4] One issue that has been raised is the disposal of wastewater created by the fracking process.
