Population Flashcards
What will happen to the world’s population in the future?
Throughout the future, the world’s population will rapidly increase in a continuous manner.
Why do you think the world’s population will increase in the future?
In my opinion, this would happen because as medical technology advances, the global death rate will be reduced. Moreover, as new babies are being born, the natural increase around the world is quite high resulting in the gradual increase of the world’s population. This occurs as a result of traditions that include having large families and poverty, where having many children is a source of income.
How does population density vary around the world and why?
Poorer areas or areas containing abundant natural resources and providing an ideal living environment or usually more densely populated. On the other hand, richer areas or areas with few natural resources and an uncomfortable living environment are usually sparsely populated.
Why is population growth faster in some countries than others?
People living in poorer countries, also known as less economically developed countries (LEDCs) tend to have larger families as a source of income. Meanwhile, richer countries which are referred to as more economically developed countries and EDCS usually have a lower population because parents strive to ensure a high quality life for each child.
How and why is life expectancy higher in some countries than others?
Life expectancy is higher in richer countries (MEDCs), where medical technology is more advanced and there is a more comfortable, cleaner living environment. This increases the average life expectancy. On the other hand, poorer countries (LEDCs) where there’s a lack of hygiene and less medical services available experience a lower life expectancy.
What is the impact of a large population on our planet?
A large global population would mean more resource consumption and excess waste produced, which can harm the environment. Furthermore, many habitats will need to be destroyed to provide enough space for living. This will result in the extinction of many wildlife species.
What is a renewable resource?
Natural resources such as wood or cotton that we can grow, make more of or replenish naturally.
What is a non-renewable source?
Resources that will eventually run out; they cannot be naturally replenished. Examples: coal, oil and natural gas.
What does birth rate mean?
The number of births per one thousand people of the population annually.
What does death rate mean?
The number of deaths per one thousand people of the population annually.
What is population density?
The average number of people living in a place, per square kilometre (km2).
What is population distribution?
How the people in a country are spread out.
What is life expectancy?
How many years, on average a newborn baby can expect to live for.
What is natural increase?
The difference between the number of births and deaths recorded over a period of time.
Who were hunter-gatherers?
People who lived by hunting animals as well as collecting fruits and vegetables along with their seeds.
