Read each question carefully and provide thoughtful, detailed answers. For multiple-choice questions, select the best answer. For short-answer questions, use the lines provided.
1. Which of the following best describes the current trend in global human population growth?
Exponential growth with no signs of slowing.
Linear growth, steadily increasing at a constant rate.
Growth that is slowing but still increasing, approaching logistic growth.
Population decline due to decreasing birth rates.
2. The 'demographic transition model' explains population change over time. Which stage is characterized by low birth rates and low death rates, leading to a stable or slowly growing population?
Stage 1: High stationary
Stage 2: Early expanding
Stage 3: Late expanding
Stage 4: Low stationary

4. Describe two significant environmental impacts of rapid human population growth. Provide a brief example for each.
5. The total number of live births per 1,000 people in a population in a year is known as the .
6. The shift from high birth and death rates to low birth and death rates as a country develops economically is called the .
