Kudzu: So Bad It Even Makes the Air Worse!

Kudzu, an invasive plant in the southeastern US, is not only a physical nuisance but also impacts air quality by altering the nitrogen cycle. It converts atmospheric nitrogen into forms that contribute to ozone formation, worsening air pollution. Research suggests kudzu could increase unsafe ozone days, highlighting the complex challenges of managing invasive species and their environmental effects.

What is one of the primary reasons kudzu is considered a problem in the southeastern US?

• It is a protected species.

• It is a rare plant species.

• It is difficult to cultivate.

• It is aggressively invasive.

How does kudzu affect the nitrogen cycle?

• It depletes nitrogen from the soil.

• It fixes nitrogen, making it available as a nutrient.

• It prevents nitrogen from being absorbed by other plants.

• It has no effect on the nitrogen cycle.

What harmful gas does kudzu contribute to the atmosphere?

• Carbon dioxide

• Methane

• Nitrous oxide

• Sulfur dioxide

Why is ozone at ground level a concern?

• It is beneficial for plant growth.

• It helps in reducing air pollution.

• It is harmful to the respiratory system.

• It has no effect on humans.

What challenge does kudzu present to environmental legislation?

• It cannot be controlled by laws targeting nitrogen emissions.

• It is resistant to all forms of herbicides.

• It grows only in protected areas.

• It is a protected species under environmental laws.
