Pic. 27. From population to cars to forests - graphs of the increasing pressures on our planet

BBC News Online's Planet under Pressure series takes a detailed look at six areas where most experts agree that a crisis is brewing:

 An estimated 1 in 6 people suffer from hunger and malnutrition while attempts to grow food are damaging swathes of productive land.

 By 2025, two-thirds of the world's people are likely to be living in areas of acute water stress.

 Oil production could peak and supplies start to decline by 2010.

 The world's greatest environmental challenge, according to the UK prime minister Tony Blair, with increased storms, floods, drought and species losses predicted.

 Many scientists think the Earth is now entering its sixth great extinction phase.

 Hazardous chemicals are now found in the bodies of all new-born babies, and an estimated one in four people worldwide are exposed to unhealthy concentrations of air pollutants.

All six problems are linked and urgent, so a list of priorities is little help.

It is pointless to preserve species and habitats, for example, if climate change will destroy them anyway, or to develop novel crops if the water they need is not there.

And underlying all these pressures is a seventh –

 There are already more than six billion of us, and on present trends the UN says we shall probably number about 8.9 billion by 2050.

Population growth means something else, too: although the proportion of people living in poverty is continuing to fall, the absolute number goes on rising, because fecundity outstrips our efforts to improve their lives.

Poverty matters because it leaves many people no choice but to exploit the environment, and it fuels frustration.

Above all, it condemns them to stunted lives and early deaths - both
