The other day, on my way home from work at night, my car hit a deer. The deer came out of nowhere before I noticed it. My car sufffered some minor damage. I suppose the animal got badly injured, but I have no idea if it survived the collision.
I hear that the number of deer has been increasing for the past decades in Japan and that the rise has been causing serious problems.
What might be a more serious problem is that humans have increased in number greatly.
