How Human's Population Went from 1 Billion to 7.7 Billion

Agricultural Revolution

1701

During this year, better farming technology was invented such as the seed drill and the horse hoe. With these agricultural advancements, farmers could now produce more food with less land. Therefore, there will be more food, less farmers and an increase in population due to higher birth rates and death rates (Child Mortality).

Hygiene Improvement

1750

People were able to solve their hygiene problem with new sewage systems and would clean themselves more often. They also added flushable toilet (1852). This slowed down the spreading of many diseases and this caused lower death rates which meant population growth.

Industrial Revolution

1760

The industrial revolution started in 1760 and ended around 1840. During this period, people started mass producing objects with steam engines. During the industrial revolution, people started mass producing clothing and started producing electricity. Mass producing clothing with the help of cotton mills made clothing cheaper and more accessible.

First Vaccine - Small Pox

1796

Small Pox killed a lot of people before vaccines were created. This invention made it so people could become immune to this disease. This vaccine slowed down death rates and caused the creation of more vaccines in the future which would decrease death rates.

Transportation

1804

The first powered steam locomotive was invented. This meant that there was faster transportation for food and resources to people and cities. Transportation with the help of the agricultural revolution could now create cities where not everyone has to be farmers. This also meant that more people could be fed from the transportation of food and people could focus on work other than farming.

Central Heating

1835

The first central heating unit was installed in a hospital. With heating, patience will not have to face harsher temperature while sick and children will not die from cold when born. This will cause lower child mortality and death rates.

First Antibiotic - Penicillin

1928

Penicillin was created and it helped fight harmful bacteria. This helped people flight bacterial based illnesses which helped decrease death rates.

Global Trade and Improved Transportation

1950

Many different countries could now trade with other countries. This meant that everyone could access resources and therefore countries would make industries and many other tasks more efficient. More efficiency will decrease child mortality rates. Global trade will also give countries access to antibiotics and vaccines that they could not manufacture which will decrease birth rates.
