Trash in the trees

Went for a walk at Jells Park, which is a local picnic area with a nice lake to walk around. This day, I went equipped with my macro lens to see what I could discover. The park is set in natural bushland, so finding subjects that stand out was a bit of a challenge.
The first two photos were of weed flower heads, but still interesting.
The third photo was a man-made fruit growing in a tree branch. I don't know why people have to dump their rubbish wherever they please and spoil nature for the rest of us.
