Question

why is urban population more affected by pollution

Answer 1

Urban people change their environment through their consumption of food, energy, water, and land. And in turn, the polluted urban environment affects the health and quality of life of the urban population. ... For example, urban populations consume much morefood, energy, and durable goods than rural populations.

Answer 2

Human beings have become an increasingly powerful environmental force over the last 10,000 years. With the advent of agriculture 8,000 years ago, we began to change the land.1 And with the industrial revolution, we began to affect our atmosphere. The recent increase in the world’s population has magnified the effects of our agricultural and economic activities. But the growth in world population has masked what may be an even more important human-environmental interaction: While the world’s population is doubling, the world’s urban population is tripling. Within the next few years, more than half the world’s population will be living in urban areas.2

The level and growth of urbanization differ considerably by region (see Figure 1). Among developing countries, Latin American countries have the highest proportion of their population living in urban areas. But East and South Asia are likely to have the fastest growth rates in the next 30 years. Almost all of future world population growth will be in towns and cities. Both the increase in and the redistribution of the earth’s population are likely to affect the natural systems of the earth and the interactions between the urban environments and populations.
