tree protection - 3 sizes


these three robots are the three different types of tree protection mechas roaming the face of the earth, in a couple of thousands of years. man kind was in grave need of tree, and since the destruction of the rainforests grew ever so violent, governments developed a tree protection plan. these robots are armoured carriers of one of the most valuable things to man kind. however, the protection of tree could ofcourse not stop the "depletion" of man.
