A local Port Talbot resident has said he wishes Banksy had created his artwork "somewhere else" because it is creating too much stress and disturbance for the owner of the garage it appears on.
The artwork, which appeared just before Christmas, shows a child with what appears to be snow falling on him, but the other side reveals a fire in a skip emitting ash.
Around 24 hours after it appeared, Banksy confirmed it was his creation with a video on his Instagram account, with the caption "Seasons Greetings".
Thousands of people have visited the site resulting in the garage owner Ian Lewis having to erect a screen around the work to protect it. He has also had to employ round-the-clock security.
Gary Owen, who had messaged Banksy on Instagram asking him to do a piece depicting the pollution in the area, says it should have been done on a council building so it falls under the responsibility of the local authority.
Kevin Gregory guards the artwork and sleeps in a caravan next to the mural.
First Minister Mark Drakeford said he will be speaking to the Culture Minister Dafydd Elis-Thomas about what help can be provided.
