An item may sometimes be described as being a virtual item when it is a representation or non-tangible abstraction of the physical object, or is a functional emulation or simulation of it.
Warming brought on by climate change is causing the icebergs in the Antarctic to drift towards the shore and cause fundamental damage to the rich sea bed ecosystem. The icebergs are scouring the sea floor as they drift close to shore of the west Antarctic Peninsula (WAP). This movement is fundamentally altering the rich sea bed ecosystem.
