Ravi visits his village after every 2-3 years. During his previous visit, he saw a number of trees and farmland around his village. This year, on his visit, he saw that the trees had been cut and farmlands had also pushed some distance away. Instead, tall buildings and industries had come up. There were no green areas in between. He also felt that air was not as much pure as it used to be earlier. He started coughing as well.
