Week 5 - Trees
"Humans have always relied upon trees. They provide food, clean air and water, shade, building materials, mulch, habitat, historical records, windbreak, fiber, medicine and more. Without trees we wouldn’t have the diversity of plants, animals, materials and resources necessary to support human life. We are in a symbiotic relationship with trees. The tree interacts with every level of an ecosystem."
