The rise of megacities
You are probably reading this in a big city. Population growth is much faster than before, and that’s especially true in cities like Tokyo and Shanghai.
People from the countryside move to the city to find work and a better standard of living. These cities are too big and are named megacities. The largest megacities are Tokyo, followed by Shanghai, Jakarta, and Manila. Next is London, with a relatively small population of 15 million.
However, life in the cities is not always better. Homelessness is a big problem. People are often in slums where poor health care and disease are problems.
Many problems also affect the rich. Traffic clogs roads for hours in cities like Bangkok and Mexico, and air pollution is so heavy in some countries that people don’t want to go outside.

3. Practice
Read the text
It took hundreds of thousands of years for the world population to grow to 1 billion. However, in just another two centuries, it grew sevenfold. You know, in 2011, the total population of the world reached 7 billion. And today, it’s about 7.5 billion. Tokyo, with 37.8 million residents, continues to be the largest city in the world in terms of population.
Advances in modern medicine are the main cause of this dramatic growth in the world population. It helps the birth rates increase and the death rates decline. The second contributor is the improvement in living standards. This leads to the rise of global lifespan, from 64.8 years in the early 1990s to 70.0 years today. Last but not least, the number of women of reproductive age is increasing day by day.
However, the rapid population growth can lead to the shortage in medical and educational facilities and services. The population grows fast compared to the demand for energy also increases. Therefore, energy shortages are also a big problem. In addition, air, water and land pollution caused by growing population in big cities has bad effects on people’s health.
Match the paragraphs with their corresponding headings.
Question 1: Paragraph 1
A. Causes of population growth
B. Population explosion
C. Consequences of population growth
Question 2: Paragraph 2
