Should the U.S. export natural gas?
The answer depends on what you think about hydrofracking.
Historically, the U.S. has had to supplement domestic natural gas production with imports, but now the extensive use of hydraulic fracturing to extract gas from shale could allow America to become a gas exporter. A recent article in Barron's suggested that the U.S. could become the world's largest exporter of gas by 2017.
But let's be clear. When we're talking about natural gas exports, we're talking about shale gas.
That is, we're talking about fracking. So let's reframe the question: Should the U.S. be fracked to supply foreign nations with gas?
The objections to fracking are legion, and each one needs to be weighed in the balance if the U.S. is to develop a prudent gas export policy.
We know, for example, that fracking even a single shale gas well requires millions of gallons of fracking fluid, and produces huge quantities of toxic wastewater.
All of this fluid has to be transported, usually by truck, and that means hundreds of diesel trucks going to and from each well pad. The exhaust from these trucks combines with the methane and volatile organic compounds released into the atmosphere during the extraction process to produce ozone.
It's no exaggeration to say that, because of fracking, some rural communities have higher ozone levels than Los Angeles on a bad day.
Developing a giant shale formation like the Marcellus will entail injecting hundreds of billions of gallons of toxic fluid underground, and no one can say with any certainty how this might impact our drinking water supplies in the years and decades to come.
We do know that a recent geochemical study conducted in northeastern Pennsylvania found naturally occurring pathways between underground shale formations and shallow drinking water aquifers. The fact that the industry insists that fracking be exempt from the Safe Drinking Water Act is not reassuring.
And of course there are other issues to consider, including the recent peer-reviewed studies that indicate that shale gas is, from a greenhouse gas perspective, worse than oil or coal. Health care professionals say we don't know what effect fracking will have on human health, while economists worry that disruptive extraction activity might damage local economies by crowding out long-term sustainable businesses like agriculture and tourism.
Right now the U.S. doesn't have the infrastructure it needs to become a major gas exporter. Canada and Mexico don't need our gas, and the liquefied natural gas (LNG) export terminals that will be necessary to tap lucrative markets in Europe and Asia have not yet been built.
Constructing the eleven huge LNG export terminals now on the drawing boards will cost more than $100 billion.
Tens of billions more will be needed to build pipelines to bring the gas to the coastal terminals. Should the U.S. pour this kind of money into fossil fuel infrastructure at a time when scientists warn that we are already suffering the adverse impacts of climate change?
The Obama administration has held up licensing export terminals until after the election. This winter, when licensing is again on the table, scientists, health care professionals and concerned citizens who oppose fracking may find themselves allied with manufacturers who realize that competition with foreign markets will drive up costs for both American industry and consumers.
Finally consider this: If the U.S. does export shale gas, it will be supplying countries like France that have already banned fracking because it's too dangerous.
Is the U.S. on its way to becoming an energy extraction colony for other nations?
Are we the new Third World?

It is pretty amazing that in this moment when the COVID-19 outbreak has much of the country holed up in their homes binging Netflix, the most watched show in America over the last few weeks has been focused on wildlife trade — which scientists believe is the source of the COVID-19 pandemic. Make no mistake: Tiger King: Murder, Mayhem and Madness is about wildlife trade and other aspects of wildlife exploitation, just as surely as the appearance of Ebola, SARS, MERS, avian flu and probably COVID-19 in humans is a result of wildlife exploitation. As a conservationist, this is one of the things I've been thinking about while watching Tiger King. Here are five more:

With the coronavirus pandemic quickly spreading, U.S. health officials have changed their advice on face masks and now recommend people wear cloth masks in public areas where social distancing can be difficult, such as grocery stores.
But can these masks be effective?

Bayer AG is reneging on negotiated settlements with several U.S. law firms representing thousands of plaintiffs who claim exposure to Monsanto's Roundup herbicides caused them to develop non-Hodgkin lymphoma, sources involved in the litigation said on Friday.
With many schools now closed due to the current COVID-19 outbreak, you may be looking for activities to keep your children active, engaged, and entertained.
Although numerous activities can keep kids busy, cooking is one of the best choices, as it's both fun and educational.
Germany's target for renewable energy sources to deliver 65% of its consumed electricity by 2030 seemed on track Wednesday, with 52% of electricity coming from renewables in 2020's first quarter. Renewable energy advocates, however, warned the trend is imperiled by slowdowns in building new wind and solar plants.
