Fracking.
Petroleum. Without it, the current world as we know it would be tossed upside down. Transportation of goods would cease. Your daily commute time would increase. Many of the products we enjoy would cease to exist. Let's face it, the rubber coating that is applied to the hull of submarines that allows them to more easily escape sonar detection and become stealth ships of war, would not be available. Who civilizations would be brought to their knees.
So powerful is petroleum, that without it, many of us would also cease to exist. Its impact on socio-cultural aspects of industrialized nations is often taken for granted, and often even marginalized.
Petroleum makes our world go 'round!
However! Petroleum extraction, processing, and refining is incredibly toxic to our environment. If you're not immediately inhaling it's byproducts, you're likely eating its contaminants through seafood, beef, pork, chicken, and even vegetables.
All the waste that is disposed of in our fresh-water lakes and streams can possibly contaminate not just you directly, but also the aqua-life such as fish, crawdads, plants, trees, and any animal or creature drinking from it. And just where do all streams and lakes flow? To the oceans no less! Infecting tuna, shrimp, halibut, crab, dolphins, wales, you name it!
I don't mean to sound paranoid, but I am intending to sound off an increasingly important alarm.

Hydraulic Fracturing/Petroleum
Hydraulic fracturing is a method that uses sand-water mixtures that are forced into underground wells under pressure; the pressure splits the petroleum-bearing sandstone, thereby allowing the oil to move toward the wells more freely.
I recently wrote a paper about the current situation involving the extraction of oil from the Bakken formation, and the excess amount of waste involving natural gas that is burned off into the atmosphere by oil companies in eastern Montana and western North Dakota, and it's implications to the atmosphere in the form of greenhouse gases, and also from a business-ethics perspective and how the corporate social responsibility of oil companies is drastically, and incomprehensibly lax.
I will post my paper, along with its citations and related published articles and journals soon.
Here is a list and reduced glossary of some of the chemicals, processes, and terms used and involved in the hazardous waste produced from fossil fuels:
asphaltenes
The part precipitated by addition of a low-boiling paraffin solvent such as normal pentane and benzene-soluble fraction, derived from carbonaceous sources such as petroleum, coal, or oil shale.
boiler slagA black granular material that is coarser than conventional fly ash.
BTEXThe BTEX chemicals (benzene, toluene, ethylben-zene, and xylenes) are volatile monoaromatic hydrocarbons that are commonly used in crude petroleum and petroleum products.
characteristic hazardous wasteWaste solids, liquids, or containerized gases that exhibit ignitability, corrosivity, reactivity, or toxicity characteristics.
coal bottom ashThe coarse, granular, incombustible byproduct that is collected from the bottom of furnaces that burn coal.
coal combustion by-products (CCBs)Fly ash, bottom ash, boiler slag, and flue gas emission that are produced when coal is burned.
drilling mudWaste stream associated with drilling operations, including oil-based mud (OBM), synthetic-based mud (SBM), and water-based mud (WBM).
drilling wastesWastes that are associated with oil exploration and production (E&P).
exploration wastesWastes that are primarily related to drilling and well completion.
fly ashThe fine powder formed from the mineral matter in coal, consisting of the noncombustible matter in coal plus a small amount of carbon that remains from incomplete combustion.
flue gas desulfurization (FGD) gypsumAlso known as scrubber gypsum; it is the by-product of an air pollution control system that removes sulfur from the flue gas in calcium-based scrubbing systems.
fossil fuelsThe biomass that produces coal, gas, oil, and tar sands.
heavy crudeCrude oil that contains a relatively high portion of residuum.
listed hazardous wastesWastes from nonspecific sources and wastes from specific sources and discarded commercial chemicals.
methyl tertiary-butyl ether (MTBE)MTBE is a gasoline additive and is highly water soluble.
naphthaThe petroleum fraction ranging from low-boiling C4 hydrocarbons to those boiling as high as approximately 220°C.
polycyclic aromatic hydrocarbons (PAHs)Often referred to polynuclear aromatics (PNA); they are a class of very stable organic molecules composed of only carbon and hydrogen.
produced waterWater produced in association with crude oil.
proppants/frac sand wastesSemisolid sludge consisting of aluminum silicate beads and formation sand.
residuumThe petroleum fraction boiling above 343°C.tank bottom wastes
Sediment that accumulates in the bottom of oil field vessels and pipelines when fluid turbulence is low.
waste oilOil arising as a waste product of the use of oils in a wide range of industrial and commercial activities.
workover and completion wastesWastes from operations in which an oil well's head is partially open to the atmosphere and is filled with a water-base fluid that maintains pressure on the formation to prevent blowout.
**************Here is a list of oil refining products, definitions, and processes: **************
alkylation
A process using sulfuric acid or hydrofluoric acid as a catalyst to combine light olefins and isobutane to produce a high-octane product known as alkylate.
°API gravityA scale of liquid specific gravity (SG) that indicates the lightness or heaviness of hydrocarbons, defined by [(141.5/SG) -131.5].
catalytic crackingA process for the breaking-up of heavier hydrocarbons into lighter hydrocarbon fractions by the use of heat and catalysts.
cetane numberA measure of ignition quality for kerosene, diesel, and heating oil, using a single-cylinder engine.
cokingA process for thermally converting and upgrading heavy residues into lighter products and by-product petroleum coke.
crude oilA complex mixture of hydrocarbons containing low percentages of sulfur, nitrogen, and oxygen compounds and trace quantities of many other elements.
deasphaltingA process for removing asphaltic materials from reduced crude, using liquid propane to dissolve nonasphaltic compounds.
hydrocrackingA process used to convert heavier feedstock into lower boiling point, higher value products. The process employs high pressure, high temperature, a catalyst, and hydrogen.
hydrodesulfurizationA catalytic process for the removal of sulfur compounds from hydrocarbons using hydrogen.
isomerizationA catalytic process for the conversion and skeletal rearrangement of straight-chain hydrocarbons into branched-chain molecules of higher octane number.
methyl tertiary butyl ether (MTBE)An ether added to gasoline to raise octane number and enhance combustion.
octane numberA measure of resistance to knocking of gasoline under laboratory conditions that simulate city driving conditions.
olefinsUnsaturated hydrocarbons, such as ethylene and propylene, that have a double carbon bond, with the molecular formula CnH2n.
paraffinsSaturated aliphatic hydrocarbons with the molecular formula CnH2n + 2.
reformingA process for the transformation of naphtha into products with higher octane number. Reforming comprises isomerization, cracking, polymerization, and dehydrogenation.
visbreakingA low-temperature cracking process used to reduce the viscosity or pour point of straight-run residues
