How do you draw attention to the scourge of plastics polluting our oceans? If you're an artist at the U.N. Conference on Sustainable Development, being held in Rio through June 22nd, you use plastic bottles to build a trio of gigantic fish, then illuminate them on the beach.

This year's conference highlights plastic as one of the most problematic ocean pollutants. The conference marks the 20th anniversary of the 1992 United Nations Conference on Environment and Development (UNCED), better known as "The Earth Summit."
