(10 pts)For many people who live in cities, parks are an important part of the landscape.They provide a place for people to relax and play sports, as well as a refuge from the oftenharsh environment of a city. What people often overlook is that parks also provideconsiderable environmental benefits.Line 5One benefit of parks is that plants absorb carbon dioxide—a key pollutant—and emitoxygen, which humans need to breathe. According to one study, an acre of trees can absorbthe same amount of carbon dioxide that a typical car emits in 11,000 miles of driving. Parksalso make cities cooler. Scientists have long noted what is called the Urban Heat IslandEffect: building materials such as metal, concrete, and asphalt absorb much more of thesun’s heat and release it much more quickly than organic surfaces like trees and grass.Line 10Because city landscapes contain so much of these building materials, cities are usuallywarmer than surrounding rural areas. Parks and other green spaces help to mitigate theUrban Heat Island Effect.Unfortunately, many cities cannot easily create more parks because most land isalready being used for buildings, roads, parking lots, and other essential parts of the urbanLine 15environment. However, cities could benefit from many of the positive effects of parks byencouraging citizens to create another type of green space: rooftop gardens. While mostpeople would not think of starting a garden on their roof, human beings have been plantinggardens on rooftops for thousands of years. Some rooftop gardens are very complex andLine 20require complicated engineering, but others are simple container gardens that anyone cancreate with the investment of a few hundred dollars and a few hours of work.Rooftop gardens provide many of the same benefits as other urban park and gardenLine 25spaces, but without taking up the much-needed land. Like parks, rooftop gardens help toreplace carbon dioxide in the air with nourishing oxygen. They also help to lessen theUrban Heat Island Effect, which can save people money. In the summer, rooftop gardensprevent buildings from absorbing heat from the sun, which can significantly reduce coolingbills. In the winter, gardens help hold in the heat that materials like brick and concreteLine 30radiate so quickly, leading to savings on heating bills. Rooftop vegetable and herb gardenscan also provide fresh food for city dwellers, saving them money and making their dietshealthier. Rooftop gardens are not only something everyone can enjoy, they are also aLine 33smart environmental investment.
