Improve food consciousness

In my place (Germany), food security probably is also not totally given, but much more than in other parts of the world (e.g. Africa, Asia) at least. Normally, nobody has to die here because of starvation or famine. Consequently, it seems like there is already an existing system against hunger which is working pretty well. For example, there is the aid organisation "Die Tafeln" which provides food to poor people for a reduced price or even for free. The food they provide is not from less quality but would have been thrown away otherwise. This leads us to one of the actual problems we have in Germany: too much food (which still is edible) is thrown away! This is an enormous waste of valuable food of which a lot of other countries would have been happy to provide it to their people. Just recently, there have been multiple articles about the waste of food in Germany. It is said that every German citizen throws away almost 82 kg (!) of food every year which is worth 21.6 billion €/year for the entire country (http://www.welt.de/dieweltbewegen/article13920110/Spottbillige-Lebe...). Now the question is, why are people so wasteful? I'm sure that one point is that foods are getting cheaper and cheaper...too cheap! Every week, discounter (like Aldi, Lidl) try to underbid the competitor's prices which leads to very cheap prices for a lot of food. So it's not surprising that many people don't hesitate to throw away something whose best-before-date has expired, even if just one or two (!) days, because the costs for buying a new one are quite low. I think it is necessary to offer food for fair and reasonable prices, both for customer and supplier. The higher the prices are, the more conscious and respectful food will be treated by the people which has the consequence of less waste.
Another thing is to lower the imports of food which can also be produced in Germany. It is not necessary to buy apples which are from Chile or wherever. Buying more local products would lead to less airplanes, trucks and trains going all over the world and, therefore, lead to less CO2 emissions and pollution which would also curb the climate change.
