Interesting thought! I would imagine that people would appreciate the value of food more if they actually had to invest time to grow the produce themselves. But how could people living in apartments and in major cities do this?
Ah yes, I think you are on to something here. We produce enough food today to feed everyone in the world, and yet people go hungry while some people seem to have so much food that they can waste large parts without any problems. Is our food system unfair and broken?
Here is a longer article-series about our food production system. One of the proposed solutions to increase our food production is to reduce food waste:
"Another way is to reduce food losses and waste. It's estimated that approximately one-third, or about 1.3 billion tonnes every year, of the food produced for human consumption is being wasted or lost in the production process. Consumers in Europe and North-America waste between 95-115 kg per year/capita, while consumers in Asia and sub-Saharan Africa only waste around 6-11 kg per year/capita. In developed countries with medium- and high-incomes most food is wasted at the consumer level. This is food that is being wasted even though it is still suitable for consumption. In low-income countries in the developing world most of the food is lost in the production process before it even reaches the market. FAO takes this matter seriously. The UN agency considers food losses to be a "significant cost" to the world economy and serious threat to global food security and availability."
