The Urban Heat Island effect highly affects metropolises with radiation and human activity; causing warmer temperatures in cities and plant growth rates in urban areas doubled compared to rural areas ( Greg, 2003). According to the New York City Census, the human population in NYC has increased 2.1% over the last ten years, inflating human activity and industrialization in the city. This has increased the temperature levels over the years. As shown in the study of Evaluating algal growth at different temperatures, temperature increases algal growth, where algae generally reach maximum growth rate at 30 °C. At higher temperatures, the rate of growth decreases due to heat stress.
