The World Health Organization set a goal for a healthy and green city to have 8 sq/m of trees per capita. News of big trees being chopped down appears often on social media. "We need time for Bangkok to develop sustainable green areas, with more big trees," Ms Walailak told the Bangkok Post. Many big trees with large root systems are planted on small pavement areas that are not deep enough or have utility lines running underneath. Root systems sometimes cannot expand making big trees fall or suffer from bad health.
