Population and Earth's Carrying Capacity

Who made the prediction that Earth could not indefinitely support an ever-increasing human population?

• Charles Darwin

• Albert Einstein

• Thomas Malthus

• Isaac Newton

What is the basic idea behind the concept of carrying capacity of Earth?

• The Earth can support unlimited human population growth.

• There is a limit to the number of people Earth can support without causing environmental damage.

• Human population decreases naturally over time.

• Technological advancements ensure infinite sustainability.

According to the text, what has allowed food production to grow exponentially in recent times?

• Decrease in human population

• Technological advancements

• Natural resource abundance

• Reduction in food consumption

What would have happened if all humans still lived like the hunter-gatherer Mentawai people of Indonesia, according to the text?

• Earth's carrying capacity would be about 100 million people.

• Earth's carrying capacity would be about 2 billion people.

• Earth's carrying capacity would be unlimited.

• Earth's carrying capacity would not be affected.

What is the estimated range of Earth's carrying capacity mentioned in the text?

• 100 million to 1 billion people

• 1 billion to 10 billion people

• 2 billion to 40 billion people

• 50 billion to 100 billion people

What is the primary reason for the rising food prices according to the text?

• Increased consumption by middle-class Americans

• The limitations of Earth's carrying capacity

• The misuse of technology leading to habitat destruction

• A decrease in the global population

According to the text, what would be a feasible population number for Earth if everyone consumed ONLY what they needed?

• 2 billion

• 40 billion

• 75 percent of the current population

• 7.2 billion

What is suggested as a better use of technology to extend Earth's carrying capacity?

• Increasing food production through genetic engineering

• Using technology to extract more fossil fuels

• Developing technologies like solar power and electric cars

• Expanding the subsistence level of clean water

What is a consequence of running out of oil as mentioned in the text?

• Increased air and water pollution

• A potential increase in global warming

• People potentially freezing to death in winter

• A rapid increase in the use of electric cars

What is one way to help balance our habitat according to the text?

• Increasing the use of non-renewable resources

• Reducing the use of solar and wind energy

• Eating locally grown food

• Lengthening shower times
