Klimawandel

Monster monsoon rains may have loosened the mud and rock that buried and killed more than 1,000 people in the northwestern Chinese Province of Gansu over the weekend, but the mudslide in Zhouqu was more than a natural disaster.

Official records show that government-run lumber companies cut 313,000 acres of forest from the slopes of Zhouqu county between 1952 and 1990, denuding the geologically vulnerable mountainsides and subjecting them to soil erosion.

AMONG THE MANY NASTY things that humans are doing to the environment, few rank worse than destroying tropical forests. Rainforests sustain an astonishing diversity of species and keep our planet liveable by limiting soil erosion, reducing floods, maintaining natural water cycles, and stabilising the climate. Yet roughly 10 million hectares of tropical forest are destroyed every year – the equivalent of 50 football fields a minute.

While the global community is fighting wars on many fronts, the Commonwealth Secretary-General has said that there is no greater fight than climate change, "where the battle for the forest represents the front line, and the very thick of the action."
