Strengthening Tree Coverage and Air Quality Argument

Medium Critical Reasoning Strengthening Data Arguments

A recent analysis by the Urban Greenery Initiative revealed that municipalities with more tree cover tend to have better air quality, evidenced by lower levels of particulate matter in the air. This study compared data from cities with high, medium, and low tree coverage. The report concluded that increasing tree planting efforts in urban areas could significantly improve air quality.

However, some researchers argue that the relationship between tree cover and air quality may not be directly causal. They point out that factors like industrial pollution and traffic emissions also play significant roles in determining air quality.

Which of the following pieces of information, if true, would most strengthen the argument that increasing tree coverage directly enhances urban air quality?

Cities with lower tree cover have consistently been found to have higher rates of respiratory illnesses among residents.

Municipalities with more tree coverage have implemented additional policies to reduce industrial emissions.

A study found that areas with more trees had a greater diversity of plant species that positively affect air quality.

Tree planting programs in urban areas have been associated with increased community engagement and local activism.
