The actual knowledge would not be sufficient to generalize the effect of population growth in developing areas, at least that is what some researchers believe. They agree that rapid growth in today’s less developed countries have favorable effects such as economies of scale and specialization, better capacities, and motivations of younger people compared with older ones. However, rapid population growth creates high pressures on elemental resources that compromises our actual model of development as human beings. In fact, it’s often suggested that rapid population growth in developing countries intensifies environmental degradation, since more people compete for the same amount of resources. As a result, high prices on food and nonrenewable resources, pollution, land degradation and global warming are the part of the impact of this unprecedented demographic change.
One evidence of this unsustainable growth indicates that the world’s population had doubled in the last 50 years, after growing very slowly for most of the human history. According to projections, the world’s population will surpass 9 billions people by 2050. Most of the additional 2.3 billion people will enlarge the population of developing countries, which is projected to rise from 5.6 in 2009 to 7.9 billions in 2050. 1 This means that the majority of the people would be in countries where basic needs are already scarce.
The human impact on the environment is a relationship among population size, per
capita consumption and the environmental damage. In fact, people in developed countries have the greatest impact on the global environment. Therefore, the 20 per cent of the people with the highest income are responsible for 86 per cent of total consumption. For instance, a child born in the developed world adds more to consumption and pollution levels in one lifetime than do 30-50 children born in developing countries. 2
In developing economies especially without oil and natural gas...
