Gathering all the information from our map and timeline, the same countries were plotted on the bar graph to show the number of people on the earth starting with the world's population being less than 1 billion and ending with over 5. The reason for this sudden increase is due to technology, as technology advance, the more solutions we have for our human problems. For example, the invention of weapons 400,000 years ago helped the human civilisation tremendously, helping hunt animals for food, fur and etc. this invention moved our position from being in the middle to the top of the food chain. Another example is the invention of the steam engine in Belgium in 1859 which was shown on the timeline started the evolution for trains, being able to travel from one country to another, making us humans have more access to resources. Without the advancement of technology, the population wouldn't be able to reach half the amount we have now.
