The world’s population is due to reach 7 billion on Oct 31, according to the UN Population Fund.
“Extreme poverty and large families tend to reinforce each other,” says Lester Brown, the environmental analyst who heads the Earth Policy Institute in Washington. “The challenge is to intervene in that cycle and accelerate the shift to smaller families.”
“The International Water Management Institute has predicted that by 2025 about 1.8 billion people will live in places suffering from severe water scarcity.”
“Looking ahead, the UN projects that the world population will reach 8 billion by 2025, 10 billion by 2083. But the numbers could be much higher or lower, depending on such factors as access to birth control, infant mortality rates and average life expectancy – which has risen from 48 years in 1950 to 69 years today.”
“For the rich, it’s totally manageable,” Mr Bongaarts said. “It’s the poor, everywhere, who will be hurt the most.”
