In this museum, I had the chance to get through a outdoor part, I can see plenty of plants, birds and butterflies there. I can have a amicable relationship with nature. The air was so clean, and, hearing the tweet, I felt I was integrated with the harmonious nature.
The other people also behaved cautiously, just like me, do not want to disturb these beautiful elves between bushes. By staying in the path through these bushes, I am aware of Leopold's ethical responsibility to nature — we should never "conquer" the nature.
