Usually, people throwing trash affects on the environment negatively.
Mountains of garbage are useless, besides they spoil not only the air, soil and water, but also cause damage to the aesthetic natural beauty.
However, rarely, but still there are exceptions when garbage creates beauty.
There is an interesting place …
Glass Beach, Fort Bragg, California, USA.
This place is amazing with its unusual beach. In the first half of XX century there was a dump on the territory of the beach.
In the 60s the dump was closed, and since then garbage was left to itself. The mountains of broken glass, plastic and other garbage was left on the shore under the hot California sun, washed by the waves.
In the end, in 80s there was nothing left from the dump, everything that was left was a beach covered with beautiful shining glass.
