environmentalists believed that whatever the environmental effects, social and economic health and progress were necessary for people and civilization to prosper. From their perspective, environmentalists represented a dangerous and extreme view with a focus on the environment to the detriment of people, a focus they thought would destroy the very basis of civilization and lead to the ruin of our modern way of life. 2. Explain the main point concerning exponential growth and whether it is good or bad. Compare exponential growth to a logistic growth curve and explain how these might apply to human population growth. What promotes exponential growth? What constrains population growth? Exponential growth is a particularly important kind of feedback. Change is exponential when it increases or decreases at a constant rate per time period, rather than by a constant amount. When we plot data in which exponential growth is occurring, the curve we obtain is said to be J shaped. It looks like a skateboard ramp, starting out nearly flat and then rising steeply. The logistic growth curve has many determinants like disease, death, and unhealthy conditions in the environment. Also birth rate may not slow down or decrease just because the population does. Two important qualities of exponential growth are (1) the rate of growth measured as a percentage and (2) the doubling time in years. 3. Compare predictions for human population growth in developed countries versus developing countries. Why is it difficult to predict the growth of Earth’s human population?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
