the biggest factor

The world population which was about 2.5 billion in 1950 has increased to 5.75 billion in the middle of 1995. According to the UN projections, the world population is estimated to reach 7.1-7.8 billion in 2015 and exceed 10 billion in the year 2050. The major part of population increase will be taken place in developing countries which cover about 80% of the world population, and is projected to reach 85% in 2025. The population issue induces the problems of food shortage, unemployment, urban slums, deterioration of environment, etc.. and is the biggest factor that precludes economic and social development.
