I need a short personal paragraph on clean neighborhood for work.

All of us live in a neighbourhood or surrounding. We must keep our surroundings neat and clean. This will help us to live a healthy life. Keeping our surroundings clean will only help in the betterment of society. Waste or garbage should not be thrown anywhere, but only in trash bins. Throwing garbage all over the place will dirty our surroundings, pollute the environment. Controlling the use of plastic bags will help to keep our surroundings clean. One should use recycled and eco-friendly products like paper or jute bags instead of others. Littering causes land, air and water pollution. Greener surroundings look beautiful and reduce pollution. Dirtying our surroundings will cause harm to us. So, keep the surroundings clean, live happy and healthy lives.
