As I see it, there are 5 options: as detailed below, canning is an option; in @Nis' answer, salting, smoking, and drying are options. The fifth, and possibly the best option, is: Store it "on the hoof" That is to say that if you want to "store" pork for several months, perhaps you should wait until the beginning of winter for slaughter and processing. Or ...

I would probably go with either: Salting Smoking Drying Or a combination of those three. Salting has been done for quite a while here in Scandinavia, but mostly with fish. Herring to be precise.

TL;DR The chart is misleading since it compares carbon imprint by mass instead of a measure of how much a human needs to survive. Argument The chart you link contains false comparisons. They are comparing mass of foods against each other. However, you don't eat for mass, you eat for calories (or protein or nutriment, or whatever). A better comparison ...

TLDR; a few years ago vegetables grown naturally and then transported by truck over a distance of 1000-1500 km had a lower carbon footprint than vegetables grown locally in heated greenhouses. However due to technical innovations things have changed and the footprint is now equal. Expectations are that in a few years heated greenhouses will have a neutral ...

You are asking to choose between two bad systems, and the least bad choice will depend on the surplus capacity of the sewage system vs space in the landfill. Vancouver B.C. has now passed a building code against garburators. Reason: It doubled the amount of solid waste in the sewer system. The additional solids also made for more problems with blockages. ...

From http://www.treehugger.com/green-food/meat-eaters-guide-get-to-know-the-carbon-footprint-of-your-diet-lamb-beef-cheese-are-the-worst.html we have which I find pretty fascinating — certainly I would have put pork much closer to beef than either salmon or Turkey... really interesting stuff. I'd like to see as well the same graph but per calorie rather ...

A great reference on seed saving for many common (and some rather uncommon) vegetable crops is "Seed to Seed" by Suzanne Ashworth. You can find tomatoes starting on p156. The info below is cribbed from this book and other sources. (Note that saving tomato seeds is a bit more involved than many other vegetables, some of which are trivial to save, like peas or ...

Personally I use a wire rack over a cookie sheet to drain fried or greasy foods. The oil drips to the pan below and I can pour the oil into a container or dispose of it however I need to.

1kg of cheese takes around 10kg of milk to produce (more for some cheeses - e.g. parmesan is around 1:16; less for softer cheeses). So the carbon footprint of cheese is going to be at least that factor higher than that for milk (there will be a little extra from any heat/energy input into the cheesemaking process but this will be small).

In How to Grow More Vegetables, John Jeavons claims you can sustain one person on 4,000 sf (372 m²), with 60% of that space dedicated to interplanted grains and legumes. The rest of the space would be taken up by high calorie root crops (30%) and vegetables (10%). That's with high soil fertility and in a climate with at least a six month growing season, so ...

Apparently a lot can be done. Fridge triage boxes look like a good idea: Tracking what's inside the fridge with dry-erase decals also seem good, but probably takes a lot of time to manage properly. Keeping your fridge uncluttered is definitely good. Grouping similar food types together in a refrigerator to increase the awareness of available foods has ...

If you twisted my arm to choose between those two options, I would say the garbage disposal is more sustainable. Sewage goes through physical and biological process to remove contaminants and the treated water is returned to the ecosystem. Even though not all the sludge byproducts are reusable — some are only suitable for disposal — it's pretty ...

Interestingly the cashew fruits are edible and some people do cook them. Permaculturalists also eat the young leaves cooked. I don't think yield of nuts is the only issue. The other issues must include long-term soil issues and the like. While higher yields can in theory support larger populations, that's only one long-term variable. In general, nuts ...

I question your basic premise that a plant's edible yield density necessarily equates to "eco-friendly." That may turn out to be the case, but it would have much more to do with the conventional farming and production practices used, offset by any possible other sustainable uses for these disposable byproducts. Consider that most nuts come from trees that ...

I'm not sure of the legality, but here is an article on raising chickens in NYC: Urban Agriculture: Raising Chickens in New York City I looked at the NYC Ordinances and it looks like it may be possible to get a permit to keep chickens, but then it also looked like permits will no longer be issued. Check out NYC Title 24: http://72-0-151-116.tvc-ip.com/nyc/...

Since the food source that is attracting the rats is the food store next to you, you should talk with the owners of the store about taking one or more of the following measures: Make sure the rats cannot access any food or leftovers. This may be hard to do as rats can eat their way through various materials. Storing all food and garbage in metal containers ...

Although @Nis already gave an answer, I want to expand on it a little. What does it mean to preserve food? One would be to put the meat into an environment, where bugs, moulds, etc. don't exist (i.e. can't survive). The common way of doing that is to put your food in the freezer, although I have also seen people preserve grain in barrels filled with ...

Yes, being a vegetarian is more environmentally-friendly than otherwise This question has been asked and answered on Skeptics Stack Exchange, based on a claim by PETA to that point. Full details are in this answer. To summarise the summary: Production of meat is a major source of anthropogenic greenhouse gases. A vegetarian diet therefore leads to less ...

Example of two edible plants growing in Europe which can be used as a drinking straw: lovage - This plant is being used in salads and soups. The stem could be about 30 cm long and 2 cm in diameter. The plant has a pleasant aroma somewhat similar to celery. Here is an example of lovage as a drinking straw. "Liebstöckel" by 4028mdk09 - Own work. Licensed ...

There are several reasons for this. Some are subjective and some are objective. producers use different breeds of animals and different strains of plants. Instead of selecting for taste, they may select for fast growth, disease resistance, appearance, transportability (eg an apple or tomato that stays hard and won't bruise) and so on. If you have access to ...

It IS legal to have chickens in NYC and there is even an organization that helps people get set up and understand what they are getting into called the City Chicken Project. http://www.justfood.org/city-farms/city-chicken-project This interview with Elizabeth Bee Ayer, who runs City Chicken Institute in Metro NY also stated that it is legal to have ...

So I’ve just put a system in place for this, it appears to be working okay. My plan was to reduce the amount of food that goes bad in the fridge, and, as a secondary goal, to eat a wider variety of foods and make sure that I washed up after myself and so on. What makes this easy is that I have a favourite pan, I do pretty much all my cooking in my favourite ...

There is a presentation comparing the environmental impact of different vegetable oils here (direct download link to pdf!). It is shown that olive oil has less impact regarding the output of greenhouse gases and substances that contribute to acidification, eutrophication and the generation of photochemical smog though it requires more space to grow it. The ...

Jon Seymour, in his book The Complete Book of Self-Sufficiency, mentions that 5 acres (about 2 hectares) of good quality, well drained land could sustain a family of 6 persons. The answer to the question will partly depend on whether or not one chooses to consume meat and dairy products and whether or not the land should also provide timber for energy. ...

Though locally "canned" food refers to food in a metal can, I understand that in the USA the term "canning" is also used for preserving food in glass jars. I suspect you're talking about metal cans anyway. If the can is made of metal, the metal can start to corrode (ie react with oxygen) soon after the can is opened, especially since salt in the food can ...

There are two relevant disadvantages to beef: Cattle produce a lot of methane, which is a greenhouse gas. The amount of land (and energy, and fertiliser) needed to grow enough grass to feed enough cattle to provide enough beef to feed a human is many times more than that required to grow crops to feed the human directly. This is generally true for eating ...

I've done this to get a drink from a very shallow spring (seep really) Most grasses stems are small in diameter, and you have to suck pretty hard to get fluid through them. In addition, you have to cut the stem with an eye on the nodes (fat bits) in the stem. They aren't hollow there. If you are serious about this, look at some the varieties of bamboo, ...

There is a difference between reuse and recycling. Reuse is using a container again without major modifications. Recycling is transforming a container into its core elements and using that to make an entirely new object. AFAIK industrial reuse of plastic food packaging isn't done anywhere because of the risk of bacterial contamination. Many plastics are ...

we actually bred snails for quite a while on 6 boxes of 1 square meter. I never weighed the annual production, but these 6 square meter were by far sufficient. We actually stopped breeding snails because of "overproduction". They were fed on our vegetables garbage. The problem with snails is not so much the insufficient area to feed them, but more the ...
