Human Population facts:
• 2,000 years ago the estimated human population was 150 million
• By 1850, the human population was one billion. By 1930, it was 2 billion.
• It took 10,000 generations to reach 2 billion.
• The human population is now growing at a rate of about 3 people/second or 260 thousand/day or 1.8 million per week or 93 million/year
• Every 3 years, the global environment must support another 285 million people.
As a result of this rapid growth:
• Approximately 1.3 billion of the world's people are impoverished, living on the equivalent of less than 1 dollar a day. And as population steadily increases, the gap between rich and poor is widening. • Some 60% of the 4.8 billion people in developing countries lack basic sanitation, and almost one-third have no access to clean water.
• Nearly 1 billion people in the world are illiterate, two-thirds of them women.
• Despite increases in grain production that began in the 1950s, thanks to "miracle wheat" and other advances in agricultural technology, such increases seem to have leveled off in recent years. Some 841 million people today are chronically malnourished, and there are 88 "food deficit" countries. This means "they can neither feed themselves nor afford the imports they need," according to the United Nations Population Fund, a subsidiary of the UN General Assembly and the largest internationally-funded source of population assistance to developing countries.
