The UN Children’s Fund reports school attendance in Zimbabwe has rapidly declined from more than 85 percent in 2007 to just 20 percent by the third term of 2008. The UNICEF Representative in Zimbabwe, Roeland Monasch, says the cholera epidemic and the collapse of basic services are adversely affecting the population. He says children are staying away from school because they have to help their parents look for food or find ways to earn money to help support their families.

The scale of the obesity epidemic is such that the world needs a global pact on the best ways to tackle it. At present, according to Professor Philip James, an expert on nutrition, obese children outnumber the malnourished by two to one. This worldwide weight gain is sparking a marked rise in some diseases—the number of people with type two diabetes is expected to double to 366 million by 2030. According to Professor James, there is no point in blaming individuals for being overweight—we need real political leadership to change the environment that is rapidly making the world fat. The fat content of food needs to be labelled clearly, advertisers must be prevented from targeting children and governments must encourage people to get out of their cars.
