What is the main purpose of the last sentence?

Some people say that trees in a busy city are a luxury, a pleasant extra that the budget can ignore. I disagree. A single mature tree can shade a pavement on a hot afternoon, lowering the temperature where people actually walk and wait for buses. Leaves catch dust that would otherwise be breathed in, and roots absorb part of the rain that would flood the drains. Surveys also suggest that people feel calmer on streets with greenery. A city that plants trees is therefore not decorating itself; it is investing in the health and comfort of its residents.
