Habitat Obstacles
While human habitat had, since early construction of roads, sought to create ways of negotiating terrain faster, the human activity on the landscape can create obstacles in its own right. Artificial lakes and ponds, canals, and areas of agricultural cultivation, particularly those that are water-intensive such as rice-paddy fields create obstacles often more difficult then the natural equivalents. Mining activity creates quarries, and the building of roads, rail roads and dams also involve construction of cuts and fills. Seeded tree-line windbreaks, hedgerows, stone walls and plantation forests also disrupt mobility, particularly of vehicles. Lastly the urban areas in themselves represent obstacles by offering elevated firing positions and canyon-like choke points by forcing the opponent to advance through the streets.

Famous quotes containing the words habitat and/or obstacles:
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
“It is very rare that you meet with obstacles in this world which the humblest man has not faculties to surmount. It is true we may come to a perpendicular precipice, but we need not jump off, nor run our heads against it. A man may jump down his own cellar stairs, or dash his brains out against his chimney, if he is mad.”
—Henry David Thoreau (1817–1862)
