Read the passage given below and answer the question that follows:

---

The last 150 years have seen a remarkable growth in human population. This can be attributed to multiple factors such as:

- Growth in medical science.
- Development of vaccines and medicines for diseases like malaria, polio, and tuberculosis.
- Improved standard of living.
- Measures taken by different governments to provide basic support for the poor and needy.
- Improvement in the infant mortality rate.
- Government and private NGO-sanctioned census programs that document the people living in a region.

Despite the last 100 years witnessing catastrophic wars, atomic bombs, serious natural calamities like the Asian Tsunami, African droughts, Australian droughts, and other climate change-related disasters, the global population has been growing at a steady pace. It is important to realize that the natural resources endowed to us on this planet are finite. With industrial and technological progress powering the growth of large cities, increasing deforestation, and the destruction of natural resources, we are headed towards another man-made calamity, which will have serious repercussions for humanity. Birth-control measures and educating the public on the use of contraceptives have had a positive impact on population control in Asia and Africa.
