• stage 5: yet to be seen, low, little change

Question 6

Malthusian theory

Answer 6

The Malthusian Theory of Population is a theory of exponential population growth and arithmetic food supply growth, he theorized that populations grew in geometric progression, he stated that food production increases in arithmetic progression

Question 7

Malthusian theory, checks

Answer 7

• argued the higher population than the availability of food, many people will die from the shortage of food
• the correction would take place in the form of Natural Checks and Preventative Checks
