Plastic

We stopped at MACRO in Rome to see a particular art piece.

Me viewing Plastic Bags, (2001-2011)
by Cameroon artist Pascal Marthine Tayou
It is a giant vase-shaped installation made with plastic bags measuring almost 10 metres in height.

The thing that surprised me was that the bags seemed new and not repurposed.

If "plastic bags are forbidden by law and should no longer pollute or constitute a danger to the world's ecosystem" says the artist, then why did he choose to use new bags?
