Environmental Science Concepts Assessment

The video discusses overpopulation and its consequences, including climate change, acid rain, biomagnification, ozone layer depletion, smog, deforestation, and invasive species. It explains the causes and effects of these environmental issues and suggests ways to mitigate them, such as reducing fossil fuel use, promoting renewable energy, and supporting reforestation efforts.

What is a major consequence of the exponential growth of the human population?

• Reduction in pollution levels

• Greater demand for resources

• Decreased need for energy

• Increased availability of resources

Which energy source is considered non-renewable?

• Coal

• Wind power

• Hydroelectric power

• Solar power

Which of the following is a primary cause of climate change?

• Excessive use of renewable energy

• Reduction in deforestation

• Increased levels of carbon dioxide from burning fossil fuels

• Decreased levels of methane

What is a potential consequence of global warming?

• Stabilization of sea levels

• Melting of polar ice caps

• Decrease in storm intensity

• Increase in forest cover

What is acid rain primarily caused by?

• Pollutants like sulfur dioxide and nitrogen oxides

• Excessive use of solar energy

• Increased use of wind energy

• High levels of oxygen in the atmosphere

What is a temporary solution to mitigate the effects of acid rain?

• Reducing the use of solar energy

• Using more fossil fuels

• Adding buffers like crushed limestone to waterways

• Increasing deforestation

How does biomagnification affect the food chain?

• It decreases the concentration of toxins

• It increases the concentration of toxins as you move up the food chain

• It has no effect on the food chain

• It only affects plant life

Which of the following is a way to help reduce biomagnification?

• Using more artificial fertilizers

• Consuming more seafood

• Supporting organically grown foods

• Dumping waste in storm drains

What is a significant impact of invasive species on ecosystems?

• They have no impact on native species

• They only affect aquatic environments

• They help restore natural balance

• They disrupt food webs and cause economic loss

What is a key strategy to combat deforestation?

• Expanding urban areas

• Promoting slash-and-burn agriculture

• Reforestation and recycling

• Increasing the use of paper products
