Read the following passage and choose the best answer (A, B, C, D):
Today, population growth largely means urban population growth. UN projections  show the world’s rural population has already stopped growing, but the world can expect to add close to 1.5 billion urbanites in the next 15 years, and 3 billion by 2050. How the world meets the challenge of sustainable development will be intimately tied to this process.  For many people, cities represent a world of new opportunities, including jobs. There is a powerful link between urbanization and economic growth. Around the world, towns and cities are responsible for over 80 per cent of gross national product. While urban poverty is growing around the world, this is largely because many people – including the poor – are moving to urban areas.  The opportunities there extend beyond just jobs. Cities also offer greater opportunities for social mobilization and women’s empowerment. Many young people, especially young women, regard the move to cities as an opportunity to escape traditional patriarchy and experience new freedoms. Urban areas also offer greater access to education and health services, including sexual and reproductive health care, further promoting women’s empowerment and the realization of their reproductive rights. This contributes to significantly reduced fertility in urban areas, changing the trajectory of overall population growth.  The urbanization process – which is particularly pronounced in Africa and Asia, where much of the world’s population growth is taking place – is also an enormous opportunity for sustainability, if the right policies are put in place. Urban living has the potential to use resources more efficiently, to create more sustainable land use and to protect the biodiversity of natural ecosystems. Still, the face of inequality is increasingly an urban one. Too many urban residents grapple with extreme poverty, exclusion, vulnerability and marginalization. Urban land is expanding much faster than urban population, a phenomenon known as urban sprawl. It is driven in part by increasing urban land consumption by the wealthy and the increasing separation of rich and poor communities within cities. Sprawl undermines the efficiencies of urban living, and it marginalizes poor people in remote or peripheral parts of cities, often in dense informal settlements or slums.  This phenomenon can eliminate the very opportunities people seek when they move to cities. Many people in slums lack ready access to health facilities. Others rely on private, unregulated providers for health services that are free in rural areas. In some urban slums, poor women have fertility rates closer to those of rural women. The urban poor also face risky and unhealthy living conditions, such heavy pollution or high vulnerability to disasters.  The total estimated number of slum dwellers is rising – from over 650 million in 1990 to about 863 million in 2012. Almost 62 per cent of the urban population in sub-Saharan Africa lived slums in 2010, the highest proportion of any region. But slum growth is not the same as urbanization. Most evidence suggests that global urbanization is an inevitable trend, while slum growth results from the decisions to limit poor people’s access to cities, through limited service provision to informal settlements or by forced evictions and resettlement of the urban poor to peripheral or under-serviced areas.
