Circle is the symbol of bonds in Japan, I think. There is no end on circle. All people connect with someone and the connection don't have any end. Bond of people is circulated. Japanese people often use circle to express the bond.
People can't own nature. Nature is so great that we can't own it. If someone think they own nature, it is illusion. We are owned by nature rather than own it. Nature won't go just as we hope.
