Those big man-made "trees" in Singapore are made to be a useful part of the park ecology. They have solar panels to generate power, they catch rain water and moderate the tropical heat.
The huge "trunks" are made of concrete and steel, while the "branches" are big wire rods. That walkway is seven stories above ground.
At night there's a light and sound show. They expect the finished project is to be a national landmark and attraction magnet for tourism.
