- A) Affluent, more developed nations consume a disproportionate amount of Earth’s resources and produce a disproportionate amount of wastes, including carbon dioxide and other greenhouse gases that are causing global climate change. The consequences of climate change include rising sea levels, drought, and extreme weather events. Do you think affluent countries should be responsible for helping poorer, less developed countries bear the financial burden of these consequences? Substantiate your answer B) Some people are not convinced that human-induced global climate change is a real phenomenon. Using your knowledge of the scientific process and the information from this chapter, develop arguments you could use to explain the scientific basis for saying that global climate change is truly occurring and that people are responsible for it.arrow_forwardBased on current growth rates, Earth’s human population in2019 will be closest to(A) 2.5 million.(B) 4.5 billion.(C) 7.5 billion.(D) 10.5 billionarrow_forwardBelow is the output of several different models that Caterpillar has built to predic next quarter sales.
