Certainly puts most of my whines and worries in perspective.
I was just reading about New Look charging a couple of quid more for size 18 jeans, bringing it to a grand total of 12 quid. Makes you think about the luxury of being able to buy such cheap clothes and eating enough to get to that size.
I think hunger, in this sense, basically means food insecurity - not knowing where the next meal is coming from - and suffering from malnutrition. Of course, malnutrition has huge knock-on health effects, especially on children, and can affect an entire society's ability to function well.
Rising food prices are a big problem, globally, and have been for a few years. They are thought to be caused by the increase in China's food consumption, especially meat (as China has become more affluent). It's also the result of the USA and other countries converting food crops into biofuels.
What can we do? Write to your MPs and ask them to vote for increases in DFID funding to deal with the hunger crisis. If politicians know that their consituents care about this stuff, it will get more money. Donate to trusted NGOs and charities.
Just wanted to add....in addition to pw's excellent suggestions- (esp re writing to your MP) buy Fair Trade stuff when you can and talk to your dcs about why, bring you children up to care about what happens, and think that they can make a difference- talk to them about how things have changed in the past (eg women's vote, abolition of slave trade, apartheid)get them to find stuff out- people like Oxfam, CXhristian Aid have v accessible kids websites with games and stuff. Also (sorry to go on) remember that climate change is causing hunger NOW and will continue to do so, again this is something that we can all do something about even if it's only a little bit, and let your MP know yu are hoping for serious progress at the talks in Copenhaged in December. I'll shut up now.
