Modern art is made out of rubbish! Its interesting to point out how art can be used to communicate to the audience in a completely different context. Its purpose not to lie in the route of the artwork but the key factor of the message it is portraying to the audience. Such pieces of artwork like rainbow worrier that was created from 5,000 plastic bags including plastic fish in fishing nets to highlight how plastic is destroying our marine ecosystem. Their is a direct message here that too engages with the environment it is placed in. What would happen to this piece if it were to placed within four walls, in a gallery space? Would the true message be lost, would it still be present? Furthermore by presenting the difference in environment or gallery space it too has an impact on the audience who will see the work. Would an audience take a message such as what is being portrayed in this piece the same on beach as they would walking through a gallery
