Explain Like I'm Five
ReLeaf is a company that likes to make cities look more like nature. They do this by making gardens that go up high on buildings. Now they want to learn more about something called "fungi". Fungi are tiny living things that help plants grow big and strong. ReLeaf wants to use fungi in their gardens to make the plants even healthier. They also want to teach people about how important fungi are for our planet. Fungi can even help us clean up our garbage! ReLeaf is trying to be really good at taking care of the earth and making sure everything stays healthy and happy.
