What is air pollution?

Back

Air pollution refers to the presence of harmful substances in the atmosphere, which can have adverse effects on human health and the environment.

Front

Why are nonnative insects a concern for ecosystems?

Back

Nonnative insects can disrupt local ecosystems because they may not have natural predators in their new environment, leading to uncontrolled population growth and potential harm to native species.

Front

What is a nonrenewable resource?

Back

A nonrenewable resource is a natural resource that cannot be replenished at the same rate it is consumed, such as fossil fuels, minerals, and certain groundwater.

Front

How does recycling help preserve nonrenewable resources?

Back

Recycling helps preserve nonrenewable resources by reprocessing materials so that they can be used again, reducing the need to extract new raw materials.

Front

What is the primary way humans deplete resources?

Back

Humans primarily deplete resources by generating power through the use of fossil fuels, which are finite and contribute to environmental degradation.

Front

What role do mangroves play in coastal protection?

Back

Mangroves help protect coastlines by stabilizing the soil with their root systems, reducing erosion, and providing a buffer against storm surges.

Front

What are the effects of fossil fuel consumption on the environment?

Back

Fossil fuel consumption leads to air pollution, greenhouse gas emissions, climate change, and depletion of nonrenewable resources.

Front

What is the significance of natural predators in an ecosystem?

Back

Natural predators help maintain the balance of ecosystems by controlling the populations of prey species, preventing overpopulation and resource depletion.

Front

What are some common sources of air pollution?

Back

Common sources of air pollution include vehicle emissions, industrial discharges, burning of fossil fuels, and agricultural activities.

Front

How can planting vegetation help combat soil erosion?

Back

Planting vegetation, such as grasses and trees, helps combat soil erosion by anchoring the soil with roots, absorbing water, and reducing the impact of rainfall.
