Stop the CRUELTY TO TREES n plants. God planted them for a purpose: umbrella from heat, absorbent of dust, protector of soil, beauties of our landscape, wall to tsunamis, provider of fruits-food-fibre-medicine to mankind, n most of all the, the essence of life, oxygen. Let the trees be part of our existence, even in the concrete jungle that we live in now. This innovative "Green Walls", esthetic as it seems, the appreciation is deeper than the thin "walls" created.
