Read the following passage carefully and answer the questions given below in your own words :
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 often harsh environment of a city. What people often overlook is that parks also provide considerable environmental benefits.
One benefit of parks is that plants absorb carbondioxide a key pollutant—and emit oxygen which human being need to breathe. According to one study, an acre of trees can absorb the same amount of carbon dioxide that a typical car emits in 11,000 miles of driving. Parks also make cities cooler. Scientists have long noted what it called the urban Heat Island Effect: building materials such as metal, concrete and asphalt, absorb much more of the sun'* heat and release it much more quickly than organic surface like trees and grass. Because city landscape contain so much of these building materials cities are usually warmer than the surrounding rural areas. Parks and other green spaces help to mitigate the urban Heat Island Effect.
