The world’s population will continue to grow throughout the 21st century, potentially increasing from the current seven billion to ten billion, although this rise should vary across regions and countries. This will inevitably lead to exacerbation of such problems as the shortage of food and drinking water, ethnic and religious conflicts, pollution and the depletion of natural resources. New types of man-made disasters, epidemics, wars and climate change also lie in store. In a hundred years’ time the world population is likely to have stabilized at 10 billion after which it will gradually reduce.
