The document is an environmental science worksheet that contains 4 questions about topics covered in chapters 1-4 of an environmental science textbook. The first question asks for a summary of the history of the environmental movement. The second question explains the difference between exponential and logistic growth curves and how they apply to human population growth. Exponential growth is promoted initially but constraints slow growth over time. The third question compares population growth predictions between developed and developing countries and why accurate human population predictions are difficult. Exponential human growth could cause issues. The fourth question asks how system theory principles apply to Earth as a living system and interactions between humans and natural ecosystems.

Environmental Science Worksheet
Answer the following questions in at least 100 words. The
answers are found in Ch. 1–4 of Environmental Science.
1. What would you include in a brief summary on the history of
the environmental movement?
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?
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? Why should
population growth be predicted?”? What will happen if there is
exponential human growth?
4. How do principles of system theory apply to the Earth as a
living system? Explain interactions between humans and natural
ecosystems.
