Yoko Ono and her son Sean Lennon are launching a coalition of artists, musicians and filmmakers against hydraulic fracturing in New York state.
The group is called Artists Against Fracking. It comprises 146 members including big names like Lady Gaga, Paul McCartney and Alec Baldwin.
The formation of the coalition to be announced Wednesday comes as Gov. Andrew Cuomo decides whether to allow shale gas drilling using high-volume hydraulic fracturing called hydrofracking.
The group says such drilling is harmful and poses the threat of contamination. They say they want to spread awareness of the issue through "peaceful democratic action.''
Cuomo is expected to allow drilling to begin on a limited basis near the Pennsylvania border.
More than 1,000 demonstrators swarmed Albany on Monday to demand that Cuomo ban the practice.
