Last night I decided to walk to the store for something after the worst of the heat had dissipated, and to enjoy the almost full moon and the fireflies before it gets too hot and dry for them. There was such an obvious difference between the temperature as I walked across the cement parking lot and that of the grassy park I cut through or even the suburban sidewalks with their adjacent grass and trees.
Urban heat island effect is real, and covering so much of our natural surface area with cement and buildings has to be increasing the global temperature. Neighborhoods with few to no grass, trees, and shrubs are hotter, and these neighborhoods are mostly in lower income areas and those whose residents are people of color, it seems. A clear case of environmental injustice when people don't have any greenspace nearby. One thing I do is donate to Texas Trees Foundation, which plants trees in neighborhoods that don't have many, and also on school grounds. I've even volunteered for a couple of their tree plantings. It was a great way to spend a Saturday morning.
