The idea of gardening for food is a generally appealing topic. People really enjoy food, and people tend to also enjoy plants, and of course, people love to create something and watch it grow, enabling them to get an edible benefit out of it. That being said, gardening isn't instinctual and requires a bit of knowledge, dedication, and hard work to make sure it all goes smoothly. These are all aspects of life that school children can benefit from. Having a shared space for children to come together, learn, and create something beneficial for everyone, is an idea that I can personally get behind. There are even many schools near us that are doing it.
