This last activity will involve math being used to answer real world questions. First, we will look at basic population growth. The human population on Earth is growing exponentially. The table below shows the growth rate for 6 recent years. It is important to note that the rate applies to the population at the end of the previous year. So, if we were studying a population of 10,000 animals with a 5% growth rate, then at the end of the first year there would be 10,500 animals. The second year, the 5% growth rate would be applied to the new population size of 10,500 animals. Thus, at the end of the second year, there would be 11,025 animals. Year 3 would end with 11576 animals, and so on. In the questions below, you will use data about the Earth's population and recent growth rates to estimate what the population will be in the future. Year Growth Rate 2017 1.12% 2018 1.10% 2019 1.08% 2020 1.05% 2021 0.87% 2022 0.84% In September of 2022, the world population hit 7.9 billion. Over the last 6 years or so the world population has been growing at a rate of ~1% per year (see
