What is a thermostat?
Green plants can also adjust the temperature. In the area with 50% green coverage, when the temperature exceeds 29℃, the temperature will drop by about 14%, which can eliminate the heat caused by the urban "heat island effect". According to the measurement, when it is cool in summer, the temperature of asphalt pavement is 49℃, the temperature of concrete pavement is 46℃, the temperature under tree-lined pavement is 32℃, and the temperature under tree-lined green space is 28℃. The forest doesn't know that heat is real.
Green plants can also adjust humidity. The air humidity in forests is 38% higher than that in cities, and the humidity in parks is 27% higher than that in other parts of cities. The strong roots of trees can continuously absorb a lot of water from the soil and evaporate it into the air through the lush leaves, thus taking away some heat, creating a moist and fresh environment with warm winter and cool summer, warm night and cool day, and small temperature difference, which is beneficial to health and longevity.
