Human Impacts on the Environment Interacive Notes

Until about how many years ago did the human population remain fairly constant?

• 1,000 years ago

• 5,000 years ago

• 10,000 years ago

• 20,000 years ago

What gave rise to steady long-term growth in the human population?

• Industrialization

• Agriculture and livestock breeding

• Technological advancements

• Urbanization

As of 2017, what was the estimated human population on Earth?

• 6.5 billion people

• 7.0 billion people

• 7.5 billion people

• 8.0 billion people

What causes a population to increase?

• When the rate of deaths is greater than the rate of births and people moving into an area

• When the rate of people leaving an area is greater than the rate of births

• When the rate of birth and people moving into an area is greater than the rate at which deaths or people leaving

• When the rate of births is equal to the rate of deaths and people moving into an area

What type of growth pattern is described by a situation where individuals in a population reproduce at a constant rate, leading to faster growth as the population size increases?

• Linear growth

• Exponential growth

• Logistic growth

• Declining growth

Does exponential growth in human populations occur indefinitely?

• Yes, it continues forever without any decline.

• No, extreme exponential growth does not occur for long.

• Yes, but only in populations with unlimited resources.

• No, because human populations cannot grow.

What has been the historical pattern of human population growth?

• Constant exponential growth without any decline.

• Periods of growth followed by periods of decline.

• A steady state with no significant changes in population size.

• A continuous decline over time.

According to the graph in your notes, around which year is the human population predicted to reach 9 billion if the current growth rate continues?

• Between 2020 and 2030

• Between 2030 and 2040

• Between 2040 and 2050

• After 2050

What is the impact of growing populations on the environment as mentioned in the text?

• They lead to a decrease in the use of resources.

• They have no significant impact on the environment.

• They demand more resources, impacting land, air, and water.

• They improve the quality of land, air, and water.

What does "conservation" refer to in the context of the text?

• The practice of using more resources to meet the needs of the population

• The practice of using less of a resource so that it can last longer

• The practice of increasing pollution for economic growth

• The practice of ignoring the needs of the growing population
