Economic and environmental catastrophes unavoidable unless rich countries cut consumption and global population stabilizes.
World population needs to be stabilised quickly and high consumption in rich countries rapidly reduced to avoid "a downward spiral of economic and environmental ills", warns a major report from the Royal Society.
Contraception must be offered to all women who want it and consumption cut to reduce inequality, says the study published on Thursday, which was chaired by Nobel prize-winning biologist Sir John Sulston.
The assessment of humanity's prospects in the next 100 years, which has taken 21 months to complete, argues strongly that to achieve long and healthy lives for all 9 billion people expected to be living in 2050, the twin issues of population and consumption must be pushed to the top of political and economic agendas. Both issues have been largely ignored by politicians and played down by environment and development groups for 20 years, the report says.
"The number of people living on the planet has never been higher, their levels of consumption are unprecedented and vast changes are taking place in the environment. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption ... or we can choose to do nothing and to drift into a downward spiral of economic and environmental ills leading to a more unequal and inhospitable future", it says.
