With a free tree donation I was able to plant this Magnolia tree on the city sidewalk. Our sidewalk looks much more like a home than a concrete jungle it once was. Never seeing the downside of planting any foliage or flower, I was excited to see it grow over time. The effects were instantaneous. Everyone walking by seemed to feel like they were strolling through the park. The oxygen it gave seemed to quell my sinuses. Trees are shade for a hot day. Trees are swing holders and house supporting beams. Trees give us food to eat. Plant a tree it makes you stronger.
