Sir: Due to increasing deforestation, environmental degradation is on the rise, and various problems and illnesses are spreading in the big cities of Pakistan. The practice of cutting trees is resulting in polluting the environment, and thus increasing diseases. In addition, breathing problems are becoming common because of decrease of greenery. Growing more trees can bring back a cool and fresh environment that improves the quality of air. Thus, we must not cut trees, and rather we should grow more trees that will provide a calm and soothing environment for human beings and animals. ZAKIA ELLAHI BAKSH Turbat
