Overpopulation – The Human Explosion Explained

by birtanpublished on September 28, 2020

Never before in history have there been so many people on earth as right now our numbers have skyrocketed from 1 billion in 1800 to 2.3 billion in 1940 3.7 billion in 1970 and 7.4 billion in 2016.

The world population increased fourfold in the last century so what can we expect for the next century and what does population growth mean for our future

Will there be mass migration overcrowded slums in mega cities covering continents diseases and pollution chaos and violence over energy water and food and a human species focused only on sustaining itself

Will population growth destroy our way of life or is this prophecy just ungrounded panic in the 1960s population growth reached an unprecedented rate which led to apocalyptic prophecies

The poor would procreate endlessly and overrun the developed world the legend of overpopulation was born but it turns out high birth rates and the population explosion are not permanent features of some

Cultures or countries but rather part of a four-step process the whole world is going through the demographic transition most developed countries have already made the transition

While other countries are doing it right now let's go back to the 18th century when the entire world including europe was in the first stage of the demographic transition

By today's standards europe was worse off than a developing region suffering from poor sanitation poor diets and poor medicine a lot of people were born

But lots of them died just as fast so the population hardly grew women had between four and six children but only two of them would reach adulthood then the industrial revolution happened

In the uk and brought the greatest change in human living conditions since the agricultural revolution people went from being peasants to workers

Manufactured goods were mass-produced and became widely available the sciences flourished and advanced transportation communication and medicine the role of women in society shifted

And created the conditions for their emancipation slowly this economic progress not only formed a middle class but also raised standards of living and healthcare for the poor working

Population the second transition stage started better food supplies hygiene and medicine meant people stopped dying all the time especially so at a very young age the

Result was a population explosion doubling the uk's population between 1750 and 1850 the main reason families used to have lots of children was that only a few of them were likely to survive

Now that had changed so the third stage of the transition was set in motion fewer babies were conceived and population growth slowed down eventually a balance emerged fewer people were dying

And fewer children were born so the death rate and birth rate became stable britain had reached the fourth stage of the demographic transition this didn't only happen in the uk more and more countries went through the four

Stages first many births and many deaths due to bad living conditions second better living conditions leading to fewer deaths and a population explosion

Third fewer deaths resulting in fewer births and population growth came to an end but if birth rates have dropped so much why is the population still growing so fast well the children born in the population

Explosion of the 70s and 80s are having kids themselves now leading to a noticeable spike in overall population but they are having far fewer children on average than their parents

The average today is 2.5 it was 5 40 years ago so as this generation gets older and fertility declines further the rate of population growth will keep on slowing

This is true for every country in the west we tend to overlook progress in other regions of the world but actually most of the world's countries have made it to the fourth stage

Just look at bangladesh in 1971 the average woman had seven kids but 25 percent of them would die before the age of five in 2015 the mortality rate was down to 3.8 percent

And women had only 2.2 kids on average this is the rule not an exception we're not special we just had a head start it took developed countries about 80 years to reduce fertility from more than six

Children to less than three others are catching up fast malaysia and south africa did it in only 34 years bangladesh took just 20. iran managed it

In 10 years all these countries that are catching up didn't have to start from scratch and the more support they get the faster they catch up this is why programs that help lower

Child mortality or help poor nations develop are so important no matter what your motivation is whether you dream of a world where all people live in freedom and wealth

Or you just want fewer refugees coming to your country the simple truth is that it's beneficial to you personally if people on the other side of the globe can live a good life and we are getting there

The percentage of people living in extreme poverty has never been as low as today so the future of global population growth is actually not an apocalyptic prophecy at all it's a promise

Population growth will come to an end the un forecasts that the 12 billionth human will never be born at all and as the development level of the world rises the number of people with a higher

Education will increase tenfold countries who used to be in need will help advance development instead more people is going to mean more people able to advance our species
