The week before the G8 convenes once again is a natural time to reminisce about the good old days, but this is about more than nostalgia. Even in today's age of austerity, the G8 has a chance to ... tackle the forgotten scandal of hunger. A child dies every 10 seconds from malnutrition - not because their parents are reckless, stupid or lazy - but because they were unlucky enough to be born at a time and place where there is too little food available or, perhaps more tragically, where people cannot afford to buy the food that is. One in eight people in the world will go to bed hungry tonight. That's 870 million people. The total population of the G8 is just 890 million. Just imagine the urgency to act if those 870 million lived in the G8 rather than in Africa, South Asia and other poor countries. Protecting poor people from land grabs, making it easier for them to find out what companies and their governments are doing and stopping the ridiculous situation where G8 members' policies actively encourage land to be used for growing fuel rather than food: all these will help. But perhaps the biggest step forward the G8 could make would be to end the scandal that sees companies dodge more than $160bn a year in tax they should pay poor countries. It is money that could be invested in farms - providing the seeds, equipment and know how to get more food from the same plot of land. And it could be used to provide safety nets to help people whose ability to earn a living has failed to keep pace with rising food prices.
