flash freezing, as well as the increase in the globalization of agriculture (i.e. Brazil).  The globalization and flash freezing has allowed for continuace growing cycles of seasonal fruit/veggies, and the flash freezing has also increased the availability of seasonal fruits by preserving them and allowing for more distant shipping.\n\nAlso a good point that greenhouses have increased, as welll as the development of hydroponics and farming techniques using limited resources but producing higher yields.

I heard of this before, they did a experiment, on a farm where they grew grapes for wine, one side with music(classical) with speakers all over that side, and another side without music, and when the grapes, and they picked the grapes, grapes in the side with music were more fresh, less rotten , and less eaten by bugs than the side withOUT music. Th reason maybe due to Vibration from the music that keeps the bugs away from the grapes.

what the hell kind of question is this? do you eat food or what? where do you get your food from? do you grow everything yourself?

Yeah, we can manupulate plant genome as per our requirement.  we can inoculate plant with  gene responsible for producing fruits for all months.....its called "gene manupulation" which makes impossible to possible.

ask your family to try eating vegetables, since they are good for you.

It's not just from Paganism. It's about nature, and the yearly cycle. Think about it - harvest time is when there's more than enough food, so often people share it with the less fortunate. The food keeps for a limited time though, so in winter - at Yuletide - there's a big feast to use up the perishables that won't last until Spring. \n\nThen in Spring there's Eastre - at a time when birds are laying lots of eggs, and various plants are beginning to produce edible parts for the first time since the previous year. So people can finish off the emergency rations instead of saving them.

yeah, its preserved fruit. Some are lost in heating up and over time. But making your own jam and eating over the winter is much better than buying stuff in the supermarkets.

In simple terms farming provided lots more food for a lot less work. This increased the population of humanity that the world could sustain.\n\nFarming was started accidentally by gathering. When food and berries were eaten, the waste would always be thrown away in the same field by some tribes. When they returned to the site the next year they found their waste had grown into plants- since the gatherer had subconciously selected the best fruits the best food eventually came to be found in these fields (especially if the same field was also the cat-holes or latrines site). Farming was born- as a pleasant surprise to those who discovered it rather than an ingenious invention.

right! plants have the ability to produce their own food. They get essential nutrients from the sun's rays and from the soil. When plants get certain elements and/or nutrients from its major surroundings, it is therefore able to convert the nutrients into food; making the plant survive with no dependence from us.

Several reasons.\n\n1) Our crop plants have been bred for the traits of being tasty and having large amounts of energy rich material in their bodies. The wild ancestors of our food crops were almost all much smaller plants and contained large amounts poisons to discourage animals from eating them. We bred them to be larger and to have no toxins so that we could eat them easily. That also makes it easy for insect pests to eat them. However things like carrotweed and onionweed for example still retain the properties of the wild forms of carrots and onions and they are very good (or bad) weeds.\n\n2) Wild plants, even weeds, don't grow in large concentrations. You might only get a patch of wild plants a few metres across, or else the plants will be scattered with only one growing every few metres. That dispersal makes it much harder for insects to find wild plants they want to eat. We plant our crops in high density and high concentration which attracts the attention of insect pests and makes them all the more damaging.\n\n3) We alter the environment of our crop plants by keeping them watered and fertilised, removing competing plants etc. That makes garden beds an ideal growing habitat for ALL plants. In contrast the shady, compacted, dry deficient environments of th natural world will only support a limited number of plant species. What that means is that there are potentially millions of species that will grow in a garden bed if they can get their seeds there. IN contrast very few species will grow in any wild habitat. Simple probability means that we are going to have more weeds in a garden bed.\n\n4) The same act of preparing favourable growing beds for crops means that the crops are healthy and lush. That makes them prime targets for insects.\n\n5) Many food and flower species are also weeds. Olive trees for example are serious weeds in Australia and blackberries are a serious weed in New Zealand. Even more flower species have become weeds. Lantana and tea tree, grown originally for their flowers, have become a serious weeds in Hawaii and Florida respectively. So it's simply not true to say that the plants we want to grow require a lot of care. Many thousands of plants that people wanted to grow have become weeds around the world.

There is no such thing as true organic veg/fruit/meat. The field can be cross contaminated by spraying in other fields as the wind will carry fertilizers and chemicals. Plus planes dumping aviation fuel in the atmosphere can contaminate everything on the ground. Even animals like us breathe in this junk that is everywhere. It is a waste of money buying organic food, it has no extra health benefits.\nAbout Organic\n\nInteresting Facts About Organic Farming\nPesticides:\n\nOver 450 pesticide active ingredients are licensed for use in UK agriculture (1), and around 25,000 tonnes of pesticides were applied to UK crops in 2000 (2). Due to the persistent nature of many pesticides, air, water and soils are inevitably contaminated by them.\n\nSoil Association standards only allow organic farmers restricted use of seven non-synthetic pesticides that have been approved on the basis of their origin, environmental impact and potential to persist as residues.\n\nThey tend to represent the final option for pest control when other methods have failed or are known to be ineffective. They are only used on a non-routine basis following authorisation from the certifying body for a specific reason.\n\nTrace elements of pesticides often remain in our food; A "Which" report of September 2001 states "pesticides used in conventional farming are toxic chemicals which kill insects, weeds and fungi, for example. But they can also harm humans, wildlife and the environment"\n\nThe issue of pesticide residues in produce is particularly pertinent to children, who consume far more produce per pound of body weight than do adults. But with regard to children, the issue of pesticide residues is not limited to foods. There is growing evidence that children are far more sensitive than adults to the effects of pesticides in the environment, due to their rapidly developing nervous systems.\nFood additives:\n\nOrganic standards permit only a limited list of around 30 additives which are allowed in organic food products only if the authenticity of the product is respected and the product cannot be produced or preserved without them.\n\nMore than 500 food additives are permitted for use in non-organic processed foods (3). Food colourings such as tartrazine and other additives have been linked with symptoms such as allergic reactions, urticaria, headaches, asthmas, growth retardation and hyperactivity in children.\nHydrogenated fats:\n\nNo hydrogenated fats are used in organic food production. Also known as "trans-fats", they are created artificially by the hydrogenation process and are included in many processed foods to make the product more solid (for example, in biscuits and margarines).\n\nIn 1994 the Committee on Medical Aspects of Food Policy recommended reducing the amount of hydrogenated fats in the British diet (4), but they are still widely used and are present in many processed foods.\nWildlife:\n\nOrganic farming has many benefits for wildlife and the environment. For example, organic dairy farms do not cut hedges between March and October when birds are nesting. They are also restricted to cutting them once every 2 years, to provide undisturbed habitats for species such as dormice. Organic farmers are not allowed to plough up traditional meadows rich in wildlife.\n\nThe RSPB has stated that "organic farming systems benefit the environment"\n\nIn May 2000 the Soil Association and WWF-UK carried out research into the biodiversity benefits of organic farming (5). These were some of their research findings:\n\nPlants: five times as many wild plants in arable fields, 57 percent more species, and several rare and declining wild arable species found only on the organic farms.\n\nBirds: 25 per cent more birds at the field edge, 44 per cent more in-field in autumn/winter, 2.2 times as many breeding skylarks and higher skylark breeding rates.\n\nInvertebrates: 1.6 times as many of the arthropods that comprise bird food; three

i would assume it would have something to do with not having to stake plants up, etc..they would grow straighter, because their fruits, branches, etc would not weigh them down as much.  i.e. tomatoes would not have to be staked up but would naturally grow straighter and keep their fruit off the ground.

Plants store food as starch, sugar, glucose, and sometimes protien (as in pulses). And that is what we eat as fruits etc.

Well, all of your green vegetables are good, and fruits.  They all add anti-oxidants which help.

Everyone is different.  Eat everything in moderation.\nstay away from too many saturated fats, and simple carbs.\n\nEat as much un processed food as possible, \nEat as much organic food as possible.\n\nTake a quality multi-vitamin, since we are not getting the same nutrients from vegetables as we used to.

stupid quetion ... onion grows in every part of the world

It's easy . We need to refrigerate all the food, otherwise the heat in the environment will warm it a lot, which is fine for reay to eat food, but otherwise needs to be preserved from excesive heating. The clothing is just light (no bikinis on the streets or shorts). Just regular clothing but not thick fabric, cotton most of the time.
