5 0

Answer:

Point A (8000 BC): the human population was very small compared to nowadays

Point B (approx. 1350 AD): the human population underwent a drastic reduction in size

Point C (1750-2020 AD): the human population is undergoing an exponential growth

Explanation:

The emergence of agricultural practices during the early Holocene period 10000 thousand years ago enabled humans to remain in one place permanently (sedentism) and increased food resources, which had a positive impact on population growth. During this period (Point A), it is estimated that the world population was between one and ten million people. During 1345-1351 AC (point B), the world suffered the "Black Death", one of the most devastating pandemics that led to the death of up to 70–200 million people in North Africa, Europe and Asia, thereby causing a drastic reduction in human population. Moreover, scientific and technological advances in the last 250-270 years (i.e., since the industrial revolution to nowadays, point C) led to an exponential increase in the human population. Nowadays, the current world population is 7.6-7.8 billion people.
