People, people, people. They’re in every nook and cranny of this planet! Here are some population points to ponder over: 

1. World Population Day was established in 1987 by the United Nations Development Programme’s Governing Council after the global population crossed 5 billion.
2. Every year on July 11th, World Population Day is observed to increase public awareness on issues related to population, including population control. The UN Population Fund (UNPF) claims that the day “offers a moment to celebrate human progress.”
3. It’s expected that nearly 70 per cent of the world’s population will live in cities by 2050.
4.  Japan is experiencing a declining population crisis! It is home to a large percentage of people aged 65 and above. This has led to scarcity in the workforce and elderly population with no caregivers, among many other effects. To fix this issue, the government of Japan has launched various initiatives such as policies to enhance child-care services and improved housing facilities for families with children.
5. Greenland is the 12th largest country in the world but the least densely populated! There are only 0.14 people per square kilometre.
6. The world’s population reached a historic 8 billion people on 15 November 2022! This growth is because of improvements in public health, nutrition, personal hygiene and medicine.
7. There is a field of study in ecology known as population dynamics. This refers to how populations of a species change over time.  
8. Increasing population can impact our environment negatively! This is because as the number of mouths to feed and take care of increases, so does the need for extraction of resources like trees, water and fossil fuels. Environmental costs such as damage from pollution aren’t considered when making economic decisions related to production and consumption either! Population regulation is vital to help save our environment and improve the standard of living for everyone.
