Warm Up Binder Check next class! –Notes should be in chronological order, you should be able to explain your binder’s organization to me. Take out your homework. For those of you who have done it, you will grade another student’s FRQ at the end. For those of you who haven’t done it, you will do it now. I will take off 20 points for the work being late, and then I will grade it. I’m betting I’m not as nice of a grader…

Video! Crazy Swedish guy 1.How does the world in 1810 apply to the Demographic Transition Model? 2.How does the world today apply to the Demographic Transition Model? 3.Do you agree with Mr. Rosling that through green energy, aid, and trade, that global life expectancy and income per capita are going to keep improving? Why or why not?

Thomas Malthus’s Theory

Our population is growing quickly. Do you think food production will always be able to keep up with our growing population?

Thomas Malthus Lived (during population explosion of Stage 2 in Demographic Transition) Said that food production would grow linearly, while population would grow exponentially, and eventually we would run out of food

Malthus’ Critics We will not run out of food More people mean more technology People will always come up with new technology to create more food Birth rates have dropped (Stage 3 and 4), so population growth will slow down

Neo-Malthusians We will run out of food, and Malthus was right Argue that poor countries still have HUGE population growth Lack of contraceptives in developing countries Increased urbanization and growth of cities will lead to less available farm land

Review Questions! 1.How did the time period in which Malthus lived influence his theory on population? 2.Explain Malthus’s theory using the terms linear and exponential growth. 3.Name two things that opponents of Malthus use today to discredit his theory. 4.What do neo-Malthusians point to in defense of Malthus’s theory?
