Our city is a big city and the population is huge. People don't keep their surroundings clean. Nobody pays attention to the earth, even though they know that one day our earth will die because of pollution, and garbage. In the city, nobody throws the wrappers in the dustbin. Everyone should contribute to keep the city clean and tidy. If you see garbage dumped somewhere, you should call the PCMC to clean it. This is the problem that no one is contributing to save the Earth.
