Question

what is a key strategy for mitigating heat islands? expanding the use of air conditioning increasing energy use green spaces, trees, and green building features reducing the number of trees

Explanation:

Heat islands are areas (usually urban) that are significantly warmer than their surrounding rural areas. Green spaces, trees, and green building features can help mitigate heat islands. Trees provide shade which reduces the amount of solar radiation absorbed by surfaces. Green spaces can also have a cooling effect through evapotranspiration. Green building features like green roofs can insulate buildings, reduce heat absorption, and provide additional greenery. Expanding the use of air - conditioning and increasing energy use would likely contribute to heat islands (as air - conditioners release heat outdoors and energy use often involves heat - generating processes). Reducing the number of trees would remove a natural cooling element.
