Freeganism?? What???

 Freeganism is the practice of reclaiming and eating food that has been discarded. One third of the world's food is wasted in shops, restaurants, farms, factories and homes and freegans and Freeganism are often seen as part of a wider "anti-consumerist" ideology, and freegans often employ a range of alternative living strategies based on limited participation in the conventional economy and minimal consumption of resources....http://en.wikipedia.org/wiki/Freeganism

A 2004 study showed that forty to fifty per cent of all food ready for harvest in the United States never gets eaten.

The United States spends about 1 billion dollars a year just to dispose of food waste..http://www.endhunger.org/food_waste.htm 

              Many freegans get free food by pulling it out of the trash (bins) a practice commonly nicknamed "dumpster diving" in North America and "skipping" or "bin diving" in the UK, as well as "bin raiding" or "skipitarianism" (so called because the person's diet mostly involves eating out of a skip). Retail suppliers of food such as supermarkets, grocery stores, and restaurants routinely throw away food in perfectly good condition, often because it is approaching its sell-by date (without thereby becoming dangerous), or has damaged packaging.Freegans find food in the garbage of such establishments, which they say allows them to avoid spending money on products that exploit the world's resources, contribute to urban sprawl, treat workers unfairly, or disregard animal rights. By foraging, they believe they are keeping perfectly edible food from adding to landfill clutter and that can feed people and animals who might otherwise go hungry.
          
          Dumpster diving is not, however, limited to rummaging for food. Many "dumpster divers" search for anything that can be recycled or reused, from accessories to power tools in need of small repairs. Some divers collect aluminum cans, which they can then sell for a small profit. Often, these people have all sorts of equipment such as a long pole that they use to move items in the dumpster around.When searching for food, a forager may come across food waste that is not entirely sealed from the unwanted waste in the same rubbish sack. This lower quality food is commonly referred to as "Scree."As bugs, rodents and other disease carriers also forage in such places, there are risks associated with sourcing and eating such food.

5 Reasons Why the World Can Feed 10 Billion

Every year, we add 78 million people to the world’s population – equivalent to a new USA every 4 years. Demographers, mathematicians and environmentalists have been warning for years that the world’s population will eventually hit a natural limit. Although famines are more rare in some parts of the world, the number of hungry people began growing again in 2008. As global population passes 7 billion, 8 billion and onwards, many fear that mass starvation is looking increasingly likely.

1)      The Green Revolution is unfinished
        The main reason why we haven’t seen the mass starvation long predicted by the likes of Robert Malthus is the ‘green revolution’. Fertiliser and hybrid seeds raised yields across South America and then India, lifting whole countries out of a cycle of food shortages. As more and more countries have adopted better agricultural techniques, the amount of food we can grow has kept ahead of population rise

2)      We haven’t tried free trade yet
        ‘Trade not aid’ goes the standard development cop-out, but the politicians most likely to spout such platitudes are usually the first to speak up in defence of subsidies too. US and EU subsidies make it possible for farmers to sell food into export markets for less than the cost of production. Released into developing world markets, it undercuts local farmers and puts them out of business.

         Free trade is not the answer, but it is part of it. Until we sweep away the structures that destroy local food systems, we don’t know how many poorer countries could be self-sufficient, or how much food the world can produce. Incidentally, free trade is a process and an ideal. African countries should be allowed to subsidise and protect their domestic markets until they are established, just like all industrialised countries did when they were developing.

3)      A third of the food the world grows is wasted
        Here in the UK, we throw away half the carrots and potatoes and lettuces we grow because they don’t look good enough for the supermarkets. Even if it makes it to the shops, a third of the food we buy is thrown away because we’re no good at estimating portions, or because we miss things at the back of the fridge.

         Up to a third of harvests are lost in the developing world too, for different reasons. Stored grain gets damp or contaminated. Fruit gets crushed on the way to market. Through simple technologies like grain silos for storage and crates for transport, refrigeration, or machine drying, much of this loss could be prevented (pdf).
We grow enough food today to feed seven billion people, with enough surplus to let a third of it go to waste. Even the most sophisticated agricultural systems lose some in processing, but harvest loss and food waste present a clear opportunity for efficiency gains.

4)      Food is for eating
         According to law, all petrol sold in the EU needs to include biofuels in the mix, currently 2.5%. It’s supposed to reduce our dependence on fossil fuels and lower our carbon emissions, but in a world where people are going hungry, diverting food into biofuels is hardly responsible. 40% of the US corn harvest now goes to biofuels, and the corn required to fill an SUV tank with biofuels could feed an adult for an entire year.
The answer is not to cut back on biofuels and replace them with fossil fuels again – the answer is to drive less in the first place.

5)      Diet for a small planet

         Currently only half of the grain grown in the world is eaten by people. Some of that other half is turned into the aforementioned biofuels, and the rest of it is fed to animals. Whether it is farmed fish, chickens, pigs, or cows, more of us are eating meat than ever before, and more of it too. On average, it takes eight kilos of grain to produce one kilo of meat. With beef it can be twice that. If we ate less meat, less often, that grain could be freed up to feed to people directly, and it would feed eight times as many as could be fed on the meat. We don’t need to give up meat entirely, but eating less would make our food resources go further.

        Furthermore, many people in the world are just eating too much, period. Meat or not, many countries have a huge obesity problem while other countries go hungry. A little redistribution would be in everyone’s best interests.
