Demographic Change in China - China is aging rapidly. By 2050 at least a quarter of all Chinese will have reached retirement age. Old age and nursing homes are already in short supply. The health and welfare system is inadequate. Only the urban middle class can afford to hope for a dignified old age. According to Chinese tradition, children should care for their aging parents at home. But more and more seniors find they can't afford to retire. For China's farmers, there are neither nursing homes nor pensions. Climate: Colombia - Green Transport - The TransMilenio express bus network in Bogotá is considered a model for many megacities in developing countries: commuters fill up the free busses, and bus lanes and bicycle paths take the place of car-filled streets. They're almost as effective as an underground railway system, but cost only a fraction to operate. CO2 emissions from passenger and goods traffic are rising steeply in developing countries. Colombia is trying out various projects to curb that growth. Tigers Live Dangerously - How Traditional Medicine is Wiping the Animals Out - There are currently fewer than 4000 tigers living the wild. Above all, the erroneous belief among many Asians in the miraculous healing powers of tiger products is driving demand for them. In ten years the species could be extinct in the wild, with tigers surviving only in zoos. Russia and China have at least agreed to establish a protected zone on the border they share, but the fight against illegal poachers seems hopeless.
