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.
The Birmingham Institute of Art and Design (BIAD) was the art and design faculty of Birmingham City University. It has now been merged into the university's Faculty of Arts, Design and Media, [8] and is based at the Birmingham City University City Centre Campus and the Birmingham School of Art on Margaret Street.
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [155] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant, or an oil spill. Non-point sources are more diffuse.
Thermal pollution, is a temperature change in natural water bodies caused by human influence, such as use of water as coolant in a power plant. Visual pollution, which can refer to the presence of overhead power lines, motorway billboards, scarred landforms (as from strip mining), open storage of trash, municipal solid waste or space debris.
[5] [6] Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species [7] and climate change. [ 4 ] Many scientists, along with the Global Assessment Report on Biodiversity and Ecosystem Services , say that the main reason for biodiversity loss is a growing human population because this ...
A 2017 study found that 83% of tap water samples taken around the world contained plastic pollutants. [96] [97] This was the first study to focus on global drinking water pollution with plastics, [98] and showed that with a contamination rate of 94%, tap water in the United States was the most polluted, followed by Lebanon and India.
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases ( climate ...
A 2019 study found scientific consensus to be at 100%, [436] and a 2021 study concluded that consensus exceeded 99%. [437] Another 2021 study found that 98.7% of climate experts indicated that the Earth is getting warmer mostly because of human activity.
