LocalHarvest.org is a Locavore’s Ally in the Quest to Reduce Food Miles and Fight Global Warming

The concept of reducing food miles in order to fight global warming is a somewhat controversial topic within the environmental community. Measured globally, it makes sense that transporting food from one nation to another for consumption can help fight global warming if production and shipping methods are highly efficient in the exporting nation and grossly inefficient in the importing nation.

Of course, such an approach also provides the luxury of having many types of produce in season during all 12 months of the year. My point is this: importing food from another nation because we cannot reform the production methods in our own is a harmful concession not unlike the American practice of shipping electronic waste to China where it can be dumped in environmentally sensitive areas without repercussions.

Put another way, since we all must fight global warming together, we all must become locavores, people who take into account the distance our food traveled when making our retail purchases.

Nutritional science has evolved to the point that we all can feed ourselves adequately during all 12 months of the year consuming food which is grown or produced locally. The definition of local in this case is about 100 miles. I encourage you to adopt this mentality while at the supermarket or green grocer.

Of course, since many of us go so far as to drink bottled water which is shipped from the other side of the world, the move to 100% local food cannot occur overnight. I don’t expect immediate results from you and would like to recommend a very valuable tool to assist in the step-by-step process of going green by going local.

LocalHarvest.org is a wonderful website which assists consumers in calculating food miles and finding local vendors who offer the items they need which are grown or produced within a reasonable geographic distance. You can feel confident in using the free service as a key starting point in coming to grips with just how far your food travels. I maintain that local is better and I have a feeling that you will come around to my way of thinking after visiting LocalHarvest.org

Repurposing of Abandoned Mines a Fitting Response to Coal’s Immense Contribution to Global Warming

Despite what many political candidates and incumbents espouse during election years, there is no such thing as clean coal. That being said, the immense contribution to global warming of the mining and burning of coal has the potential to be offset to a certain extent. To be clear, what I am about to share with you in no way addresses mercury hotspots or other mercury-related issues which arise from our reliance on coal.

Coal mines often contain byproducts which in some cases we capture and in other cases we vent into the atmosphere. Methane gas in a common example and, tragically, its ubiquity in mines is a leading cause of sudden disasters in mining communities. The geological history of our planet is one of the main reasons that the methane is present. The gas was created and compressed over eons of planetary evolution and then trapped beneath the surface. Slicing into the Earth’s crust to extract the coal can allow the methane to escape.

If we think of mines as rudimentary tombs, the potential for repurposing becomes an intriguing concept. After all, if the Earth’s crust was solid enough and strong enough to create and retain billions of BTUs of methane, might it not be possible to use this tomb concept to store other substances? Indeed it can and sequestration is the operative word!

Environmentally speaking, we should desist all coal mining today, right now as you read this. For a variety of reasons, that won’t happen so let’s make the best of a dirty situation. The same politicians who love to blather on about clean coal also are enamored with the concept of carbon sequestration as a means of fighting global warming. The hard science behind such positions indicates that it can help but is very, very far from being a panacea.

Nevertheless, the sequestration of carbon in mines can be an important stop gap measure which I support, mostly for sentimental reasons since it was the bitumen and coke previously located in the mines which brought us the climate crisis of the new millennium. What more logical place to store some of the byproducts is there?

In my next installment, I will share with you an encouraging yet distinct repurposing of abandoned mines. It does not sequester carbon directly but can result in significant decreases in the use of fossil fuels, having a similar net effect.

Aquaculture in Abandoned Mines May Hold Key to Low-Carbon Synergies in Food Production

Last time, I told you about repurposing abandoned mines for carbon sequestration. While better than leaving them as useless crevasses, this approach has a new rival, aquaculture. You may be wondering how this could work. As it turns out, in some places it is highly effective.

One of the greatest impacts on the planet caused by global warming is shifting weather patterns, especially precipitation. This is the main reasons that Mount Kilimanjaro will be free of its permanent snow pack very soon. Fortunately, some places continue to have adequate rainfall throughout the year. One such location is the mountainous terrain of West Virginia, a spot, not coincidentally, with many abandoned mines.

The rainfall in West Virginia often accumulates in the mines. Luckily, the state of some of the mines is such that the water is suitable for raising fish with the only technical need being of circulating and purifying the water on a regular basis.

HOW ABOUT THAT!

The situation gets better, too. Because the large bodies of water are located deep underground, the temperature is fairly constant throughout the year and there is very little sunlight, which means that they are suitable for raising species of fish which grow naturally in the Arctic Ocean!

This wonderful practice is very real and occurring today. Ponder the possibilities! Appalachian aquaculture allows many of the most popular species of fish to be harvested much closer to most of North America’s urban population centers without endangering scarce natural stocks. What’s more, by growing millions of pounds of fish every year in close proximity to cities, carbon emissions are reduced greatly since much less fuel is consumed in the process.

TALK ABOUT A WIN-WIN!

Needless to say, I am very excited about aquaculture in abandoned mines and can’t think of a better way of repurposing these scars on the face of the Earth. It represents real progress and a delightful departure from the old ways of doing things!
