<em><u>Trees </u></em><em><u>provide </u></em><em><u>socio-economic benefits</u></em><em><u> by creating a friendly environment that lures more customers to the shopping areas they are found.</u></em>

- Trees take in carbon dioxide during photosynthesis, thereby purifying the atmosphere and limiting greenhouse effect.
- They also beautify the environment
- Trees serve as shades for humans
All these importance of trees is what will definitely lure people to go to shopping areas that have trees planted in them.
