According to experts, only a revolution in the use of the earth’s resources can prevent the environmental crisis, because every year the number of people are increasing.
In 1798, Thomas Malthus gloomily forecast that our ability to reproduce outpace the growth of food production, leading to starvation and extinction.
But the industrial revolution had a profound impact on agriculture, proving that Malthus and other predictors of the onset of a global catastrophe were wrong, even after a number of people has increased four-fold.
"Despite the panic forecasts, historical increase in the population does not lead to economic disaster," - said David Bloom, a professor of the Department of Health and Population at Harvard.
Today, many are wondering whether it is possible that Malthus made his prediction just a few centuries ahead of time.
October 31, the Earth’s population officially reached seven billion mark in - this is an increase of two billion in less than 25 years.
Over the past six decades, the average birth rate fell by half, to 2.5 children per woman.
But in different countries, this figure varies greatly. Stop to the growth of the world population at around 10 or 15 billion depends on developing countries, mostly from Africa, where there is the most rapid growth.
According to estimates Global Footprint Network (GFN), if the growth rate will remain the same as now, by 2030 humanity will need a second planet to meet the ever-increasing appetite and digest the rising tide of waste.
Declining birth rates will allow a population at around eight billion and bring the poor countries out of poverty, reduce the consumption of natural resources and stop climate change.
