What do you call a landform created by the wind but instead of sediments this landform is made out of trash!

 - A pile of garbage!!

Discovery News

  According to Discovery News - Biologist Erin Zylstra mapped and added up all the wind-dispersed plastic trash bags and latex balloons in two protected parts of the Saguaro National Park in Arizona. She was surprised to discover that these particular kinds of very mobile trash outnumbered desert tortoises and western diamondback rattlesnakes. Like in the oceans, the bags and balloons pose potential threats to wildlife.

 There is more trash bags and latex balloons in the desert than turtles and rattlesnakes!  What?!!!!
It sounds like one day we will see new features on Earth surface made out of trash - YUCK!!  
Question?  What is plastic made of?  What can we do to stop it?  What would you name the trash landform?
