New research suggests that while reforestation efforts may help combat climate change, they could unintentionally worsen seasonal allergies for some people. Scientists are studying how increased tree growth—particularly of certain species—might alter pollen production and dispersal patterns. The findings raise questions about balancing environmental benefits with public health concerns for allergy sufferers. Experts are now exploring ways to manage these trade-offs as global tree-planting initiatives expand.
