PRINCIPLES OF POPULATION

EDUCATIONTOPIC #9

IMPORTANT PEOPLE

An English clergyman and college professor, Published the principles of population ( 1798 ).

his publication was the first important contribution to the study of population.

Rev. Thomas Robert malthus

IMPORTANT PEOPLERev. Thomas Robert malthus

He stressed that our population was increasing more rapidly than the available food source.

IMPORTANT PEOPLERev. Thomas Robert malthus

Without population control, the population would be reduced by

catastrophes such as famine or war according to Malthusian theory.

IMPORTANT PEOPLERev. Thomas Robert malthus

These Malthusian catastrophes are naturally occurring and have not

taken place on a global scale due to the progress in

agriculture And technology.

IMPORTANT PEOPLERev. Thomas Robert malthus

He Also pointed out that human nature being what it is, the passion between the sexes appears to be fairly constant and, if unchecked population will double itself every twenty-five years.

POPULATION EDUCATION

What is population education?

Population education is an approach of addressing the consequences of the imbalance between population and world resources.

WORLD POPULATION: THE NUMBERS

WHAT ENABLED POPULATION GROWTH?1. Agriculture About 12,000 years ago, several cultures

shifted from hunting and gathering to farming.

Humans became the first and only species ever to control our own food supply, and steady population growth was the result.

WHAT ENABLED POPULATION GROWTH?2. Technology The development of agriculture led by turns

to settlement, division of labor, mathematics, literacy, and science.

The Breakthroughs in medicine, nutrition and sanitation brought down child mortality rates and led to longer life spans.

WHAT ENABLED POPULATION GROWTH?2. Technology The mechanization of agriculture and

improvements in food preservation led to even greater increases in food production and availability.

The Human numbers began doubling at an unprecedented pace.

WORLD POPULATIONAs of the latest survey of 2016,

world population is at approximately 7.4 billion people and growing.

China and India are the two most populous countries, each with more than a billion people.

WORLD POPULATION

we are still adding approximately 80 million people a year to the planet at our current growth rate of 1.2 percent.

The recent population explosion is not because of increased birth rates, but decreases in death rates, with the help of medicine, agriculture, technology, disease prevention, and Etc…

WORLD POPULATION IN THE FUTURE

Demographers expect world population to continue to grow through this century, reaching over 10 billion by 2100.

In making projections, demographers consider the following;

1. fertility trends

2. health

3. pandemics

4. War5. food security

WORLD POPULATION IN THE FUTURE

In the world today, there are three times as many people under age as over age . With such a large segment of the population yet to start bearing children, the population is expected to grow through this century, even as fertility rates are dropping.

Experts agree that the status of women around the globe is a key to population stabilization.

UNDERSTANDING CARRYING CAPACITYWhy is it important for world population to stop growing? The earth is a finite system and has a

carrying capacity for how many people can be adequately supported

carrying capacity isn’t about physical space – it’s about the types of land and resources available to sustain life.

UNDERSTANDING CARRYING CAPACITYHow many people can the earth support?

That depends on people’s lifestyles, which impacts the rates at which resources are consumed.

resources are consumed at a greater pace to enable residents to eat a diet with more animal products, use more energy in homes, and produce more goods.

if everyone lived like they do in wealthier countries, fewer people could be supported by earth’s resources that live on the planet today.

UNDERSTANDING CARRYING CAPACITYHow many people can the earth support?

Global demand for natural resources has doubled in the past 50 years.

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

There are many ways in which our large and growing human population impacts the global environment. Using resources faster than they can be replenished is just part of the issue.

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

The following are some of the devasting effects

to our environment;

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

1. Climate ChangeOur global temperature is on the rise due to the ever-increasing amount of greenhouse gases that are emitted through human activities including fossil fuel use, deforestation and livestock grazing.

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

1. Climate ChangeThis warming is causing sea level rise from Arctic ice melt, more extreme weather, and loss of habitat including coral reefs.

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

2. Water Scarcity

About 35 percent of the world’s people already face chronic water shortages. As the population grows, more water is needed for agriculture and industry, as well as for domestic uses.

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

2. Water Scarcity

The worldwide supply of clean water is reduced, and accessible water is further reduced by pollution.

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

Nearly all of the world’s ecosystems are shrinking to make way for more

humans and their homes, farms, factories and shopping centers.

3. Biodiversity Loss

ENVIRONMENTAL IMPACTSWhat are the effects of our population to the environment?

3. Biodiversity Loss

Humans depend on a rich biodiversity for survival – food, medicines, climate

regulation and more.
