As I said earlier, there is a HUGE effort in Singapore for landscapping, in part for environmental purposes. These "super trees" are metal structures with oxygen coming out the top, and the plants around the structure grow very fast and cover it in about one month.
These trees are fascinating. I wonder if there are any in other countries.
ReplyDeleteHow do they get oxygen to come out of these tree sculptures? Is it just a big tank of oxygen?
