Good morning, everyone. Today we're going to discuss the rise of urban farming. While many people think of it as a modern trend, it actually dates back to the early 20th century. However, the key point is that urban farming today focuses not just on food production, but also on community building and environmental education. In particular, rooftop gardens have become popular because they reduce the heat island effect. Yet, the main challenge remains the initial cost of setting up the infrastructure. Therefore, many cities now offer subsidies to encourage participation.
