The children of the Grace Revival School do not have far to go when they need the lavatory. They get up from their ramshackle desks and move just outside their corrugated iron classroom to the vast dungheap that stands beside the building.
There are no latrines for the 74,000 people who live in their section of Kibera, the biggest slum in Africa, which lies either side of the main railway line between Nairobi and Mombasa in the Kenyan highlands.
People there use what, with dark humour, are called "flying toilets". They defecate in a plastic bag and then throw it into the street or on to one of the vast dung heaps. Some just visit the heaps and relieve themselves directly. The heap next to Grace school is about 20 feet high and the size of a quarter of a football pitch.
The stench is unimaginable. When it rains, a noxious black liquid runs off the heap, and through the school, over the dirt floor of the classrooms. It seeps into the drinking water supply pipes, which run beneath the dump.
Earth Changes
PORTLAND, Ore. - Heavy rain and flooding, already blamed for three deaths in the Pacific Northwest, washed out a major highway near Mount Hood and forced the shutdown of 67 miles of the North Cascades Highway in Washington state Thursday.
NAIROBI, Kenya - The world's oceans are becoming more acidic, which poses a threat to sea life and Earth's fragile food chain, a climate expert said Thursday.
Oceans have already absorbed a third of the world's emissions of carbon dioxide, one of the heat-trapping gases blamed for global warming, leading to acidification that prevents vital sea life from forming properly.

Water levels began to recede in southwestern B.C. early Tuesday, but an evacuation order remained in place for residents of about 200 homes in Chilliwack and about 10 homes in Hope.
The forecast called for more showers on Tuesday. Parts of the eastern Fraser Valley were hit by 300 millimetres of rain in the last few days that caused the Chilliwack River to overflow.

Climate change cannot be stopped, so the government needs to develop realistic policies that will slow it down, according to one expert.
LONDON (Reuters) - Foreign Secretary Margaret Beckett will warn Europe on Tuesday to tackle climate change or risk terrorists seizing on famine, water shortages and failing energy infrastructures to threaten global security.
WASHINGTON - The first mass exodus of people fleeing the disastrous effects of climate change is not happening in low-lying Pacific islands but in the world's richest country, a US study said.
"The first massive movement of climate refugees has been that of people away from the Gulf Coast of the United States," said the Earth Policy Institute, which has warned for years that climate change demands action now.
Institute president Lester Brown said that about a quarter of a million people who fled the devastating impact of Hurricane Katrina a year ago must now be classed as "refugees".
"Interestingly, the country to suffer the most damage from a hurricane is also primarily responsible for global warming," he said.

IS EUROPE'S central-heating system about to break down, causing climate chaos around the world? Late last year, oceanographers reported a sudden and shocking slowdown in the currents of the North Atlantic, a critical part of the vast system of ocean circulation that influences temperatures and weather around the world. A shutdown could cause famine in south Asia, kill off the Amazon rainforest and plunge western Europe into a mini ice age.
Sea ice in the Arctic has failed to re-form for the second consecutive winter, raising fears that global warming may have tipped the polar regions in to irreversible climate change far sooner than predicted.
Satellite measurements of the area of the Arctic covered by sea ice show that for every month this winter, the ice failed to return even to its long-term average rate of decline. It is the second consecutive winter that the sea ice has not managed to re-form enough to compensate for the unprecedented melting seen during the past few summers.

Rising concentrations of greenhouse gases may have more serious impacts than previously believed, a major new scientific report has said.
The report, published by the UK government, says there is only a small chance of greenhouse gas emissions being kept below "dangerous" levels.
It fears the Greenland ice sheet is likely to melt, leading sea levels to rise by seven metres over 1,000 years.
The poorest countries will be most vulnerable to these effects, it adds.
