Local food is great, but can the concept be taken too far_ _ alternet

Without a doubt, local food has a great set of benefits. But the commonly held belief that reducing “food miles” is always good for the environment because it reduces the use of transportation fuel and associated carbon dioxide emissions turns out to be a red herring. Electricity and magnetism online games Strange as it might seem, local food uses about the same amount of energy per pound to transport as long-distance food. Gas out game commercial Why? Short answer: volume and method of transport. Electricity omd Big box chains can ship food more efficiently — even if it travels longer distances — because of the gigantic volumes they work in. 935 gas block Plus, ships, trains and even large trucks driving on interstate highways use less fuel, per pound per mile, than small trucks driving around town.

But don’t feel bad. Current electricity definition physics It turns out that “food miles” aren’t a very big source of CO2 emissions anyway, whether they’re local or not. Electricity 2015 In fact, they pale in comparison to emissions from deforestation, methane from cattle and rice fields, and nitrous oxide from overfertilized fields. No electricity jokes And local food systems — especially organic farms that use fewer fertilizers and grass-fed beef that sequesters carbon in the soil — can reduce these more critical emissions. Gas mask art At the end of the day, local food systems are generally better for the environment, including greenhouse gas emissions. Electricity gif Just don’t worry about emissions from food miles too much.

We have also seen a movement toward what you might call“super-local” food, where people grow more food right in the city. Online electricity bill payment In other words: urban agriculture.

There are commercial scale urban farms popping up, like Growing Power in Milwaukee, that grow food in vacant lots and create badly needed jobs in urban neighborhoods. Gas zone pricing Others, like Gotham Greens, are growing food in rooftop greenhouses in major cities. M gastrocnemius medialis People are also starting community gardens in their neighborhoods, where folks can share an area of land — maybe in a city park or a school yard — to grow fruits and vegetables. La gasolina And, of course, many people grow super-local food at home, in their yards, or on their patios and decks. 9gag tv In fact, my wife and I have always grown salad greens, herbs, vegetables, and a wide range of fruits at our place — whether in a tiny yard converted to gardens and orchards in Saint Paul, Minnesota, or a variety of potted vegetables, herbs, and fruit trees on a deck in San Francisco. Gas meter in spanish It tastes great, and there is a lot of satisfaction in doing it yourself. Monroe la gas prices And I love that our daughters grew up — even as city kids — knowing a little bit about where food comes from.

While it’s not a silver bullet solution to all of our global food problems, [local food is] an exciting, powerful development, and it can have important nutritional, social, economic and environmental benefits if done well.But, despite these great advances, we need to remember that urban food can’t feed everyone. Electricity powerpoint template There’s just not enough land. Gas ks In fact, the world’s agriculture takes up about 35 to 40 percent of all of the Earth’s land, a staggering sum, especially compared to cities and suburbs, which occupy less than 1 percent of Earth’s land. Electricity office near me Put another way: For every acre of cities and suburbs in the world, there are about 60 acres of farms. Types of electricity generation methods Even the most ambitious urban farming efforts can’t replace the rest of the world’s agriculture. Gas in babies how to get rid of it Fortunately, urban farmers are smart and have focused their efforts on crops that benefit the most from being super-local, including nutritious fruits and vegetables that are best served fresh. Static electricity diagram In that way, urban food can still play a powerful role in the larger food system.

So there’s a lot to be excited about with local food. Gas finder While it’s not a silver bullet solution to all of our global food problems, it’s an exciting, powerful development, and it can have important nutritional, social, economic and environmental benefits if done well.

Proponents of indoor techno-farms often say they can offset the enormous sums of electricity they use by powering them with renewable energy — especially solar panels — to make the whole thing carbon neutral.

Any system that seeks to replace the sun to grow food is probably a bad idea.These indoor “farms” would use solar panels to harvest naturally occurring sunlight and convert it into electricity so that they can powerartificial sunlight. In other words, they’re trying to use the sun to replace the sun.

But we don’t need to replace the sun. Gas x tablets himalaya Of all of the things we should worry about in agriculture, the availability of free sunlight is not one of them. Gas works park fireworks Any system that seeks to replace the sun to grow food is probably a bad idea.

A further problem with indoor farms is that a lot of crops could never develop properly in these artificial conditions. Electricity generation by country While LED lights provide the light needed for photosynthesis, they don’t provide the proper mix of light and heat to trigger plant development stages — like those that tell plants when to put on fruit or seed. E gaskell Moreover, a lot of crops need a bit of wind to develop tall, strong stalks for carrying heavy loads before harvest. Gas utility worker As a result, indoor farms are severely limited and have a hard time growing things besides simple greens.

I’m not the only critic of indoor, high-tech, energy-intensive agriculture. Static electricity vocabulary words Other authors are starting to point out the problems with these systems, too (read very good critiques here, here, here and here).

While I appreciate the enthusiasm and innovation put into developing indoor farms, I think these efforts are, at the end of the day, somewhat counterproductive.
