From the Ted Talk by Stefan Al: What happens if you cut down all of a city's trees?

Unscramble the Blue Letters

Humanity has been uncovering these arboreal bneefits for centuries. But teres aren’t just ciarcul to the health of a city’s infrastructure; they play a vital role in the health of its citizens as well. In the 1870’s, Manhattan had few trees outside the island’s parks. Without trees to provide shade, buildings absorbed up to nine times more sloar radiation during deadly summer heat weavs. Combined with the period’s poor sanitation standards, the oppressive heat made the city a breeding ground for brceiata like cholera. In modern day Hong Kong, tall skyscrapers and underground infrastructure make it difficult for trees to grow. This contributes to the city’s dangerously poor air qiautly, which can cause bronchitis and diminished lung ftiuocnn. Trees affect our mental health as well. Research indicates that the presence of green foliage increases attention spans and decreases stress levels. It’s even been shown that hospital patients with vwies of brick wlals recover more slwoly than those with views of trees.

Original Text

Humanity has been uncovering these arboreal benefits for centuries. But trees aren’t just crucial to the health of a city’s infrastructure; they play a vital role in the health of its citizens as well. In the 1870’s, Manhattan had few trees outside the island’s parks. Without trees to provide shade, buildings absorbed up to nine times more solar radiation during deadly summer heat waves. Combined with the period’s poor sanitation standards, the oppressive heat made the city a breeding ground for bacteria like cholera. In modern day Hong Kong, tall skyscrapers and underground infrastructure make it difficult for trees to grow. This contributes to the city’s dangerously poor air quality, which can cause bronchitis and diminished lung function. Trees affect our mental health as well. Research indicates that the presence of green foliage increases attention spans and decreases stress levels. It’s even been shown that hospital patients with views of brick walls recover more slowly than those with views of trees.
