Don't fool with Mother Nature

Respiratory health: The report cites the dangers of methane emissions from natural gas drilling in Texas and Pennsylvania, which have been linked to asthma and other breathing issues. Another study found that 39 percent of residents in southern Pennsylvania who lived within one kilometer of a fracking site developed upper-respiratory problems compared with 18 percent of those who lived more than two kilometers away.

Drinking water: Shallow methane-migration underground could seep into drinking water, one study found, contaminating wells. Another found brine from deep shale formations in groundwater aquifers. The report also refers to a study of fracking communities in the Appalachian Plateau where they found methane in 82 percent of drinking water samples, and that concentrations of the chemical were six times higher in homes close to natural gas wells. Ethane was 23 times higher in homes close to fracking sites as well.

Seismic activity: The report cites studies from Ohio and Oklahoma that explain how fracking can trigger earthquakes. Another found that fracking near Preese Hall in the United Kingdom resulted in a 2.3 magnitude earthquake as well as 1.5 magnitude earthquake.

Climate change: Excess methane can be released into the atmosphere, which contributes to global warming. One study predicts that fracking in New York State would contribute between 7 percent and 28 percent of the volatile organic compound emissions, and between 6 percent and 18 percent of nitrogen oxide emissions in the region by 2020.

Soil contamination: One analysis of a natural gas site found elevated levels of radioactive waste in the soil, potentially the result of surface spills.

The community: The report refers to problems such as noise and odor pollution, citing a case in Pennsylvania where gas harvesting was linked to huge increases in automobile accidents and heavy truck crashes.

Health complaints: Residents near active fracking sites reported having symptoms such as nausea, abdominal pain, nosebleeds, and headaches according to studies. A study in rural Colorado which examined 124,842 births between 1996 and 2009 found that those who lived closest to natural gas development sites had a 30 percent increase in congenital heart conditions. The group of births closest to development sites also had a 100-percent increased chance of developing neural tube defects.

In the 1910s and 1920s the southern Plains was "the last frontier of agriculture" according to the government, when rising wheat prices, a war in Europe, a series of unusually wet years, and generous federal farm policies created a land boom – the Great Plow-Up that turned 5.2 million acres of thick native grassland into wheat fields. Newcomers rushed in and towns sprang up overnight.

As the nation sank into the Depression and wheat prices plummeted from $2 a bushel to 40 cents, farmers responded by tearing up even more prairie sod in hopes of harvesting bumper crops. When prices fell even further, the "suitcase farmers" who had moved in for quick profits simply abandoned their fields. Huge swaths of eight states, from the Dakotas to Texas and New Mexico, where native grasses had evolved over thousands of years to create a delicate equilibrium with the wild weather swings of the Plains, now lay naked and exposed.

Then the drought began. It would last eight straight years. Dust storms, at first considered freaks of nature, became commonplace. Static charges in the air shorted-out automobiles on the road; men avoided shaking hands for fear of shocks that could knock a person to the ground. Huge drifts of dirt buried pastures and barnyards, piled up in front of homesteaders' doors, came in through window cracks and sifted down from ceilings. 

Some 850 million tons of topsoil blew away in 1935 alone. "Unless something is done," a government report predicted, "the western plains will be as arid as the Arabian desert."

We want it now – and if it makes money now it's a good idea. But if the things we're doing are going to mess up the future it wasn't a good idea. Don't deal on the moment. Take the long-term look at things. It's important that we do the right thing by the soil and the climate. History, is of value only if you learn from it.
