Over the past 10,000 years, humans have modified and altered the natural environment. From agriculture to industrialization, humans have changed the environment affecting the atmosphere and its surroundings. The growth in world population is masking a more important human-environmental interaction. While the world’s population is doubling, the world’s urban population is tripling. Within the next few years, more than half of the world will be living in urban areas (Torrey). It is now 2015 and a prediction made over a decade ago has become true. More than half of the world lives in urban areas. The world has shifted from becoming primarily rural and self-sustaining to urban and dependent. Humans pair progress with innovation meaning that if…show more content…
With so much progression in cities and urban areas, researchers are focusing their efforts to discover the effects of urbanization on the environment on a global scale. Since urbanization has been rapidly increasing over the past centuries, reintegrating natural systems within the cities and densely populated areas could mitigate the cities impact on the environment (Beatley). Rather than focusing on sustaining the nature on the outskirts of major cities, implementing greener areas within the urban population will increase the sustainability of these urban ecosystems. Reintroducing nature’s services throughout cities offer cost-effective improvements: cooling the environment, reducing runoff water and air pollution (Pincetl et al.). An example of how nature services help humans is cooling the environment. Heat islands are created through energy consumption in a densely populated area. Heat islands have negative effects on the environment by changing local weather patterns. Cities radiate heat back into the atmosphere at 15 to 30 percent less than rural areas do. This means that cities that create heat islands have a warmer temperature than most rural areas. Pollutants can also become trapped in these islands, making the atmosphere less clean. According to an index provided by the EPA, Los Angeles experiences a significant bump in added temperature due to the highly populated and urbanized location. The Los Angeles area attains
