In my opinion, a sustainable city connects the city back to nature where green urbanism and balanced ecosystemare promoted. Not only does it promote healthier and rich eco-cities where more plants and animals can flourish, asustainable city is beneficial to the minds, hearts, and souls of both current and future generations. It also helpsthe region move towards a possible ecotourism. One example is Singapore’s Gardens by the Bay. However, theseprojects are immensely expensive and politically and economically controversial, especially in third worldcountries. Thus, more development is required to create places that are more suitable.
