Analysis
1. What factors contributed to the world's overall population growth in the last 150 years?
advances in medicine, sanitation and nutrition and increased food production has contributed as factors of growth.
2. Why does a population not level off during the same year it reaches zero population growth?
Because there's the same amount of people being born and people dying( similar death and birth rate)
3. If the carrying capacity of the earth was 9 billion people, when would this number be reached
(according to your graph)?
by the time between 2030-2040
4. What will happen when the human population exceeds the earth's carrying capacity?
starvation will increase and the living standards will be so low that eventually death rates will increase
