Actor Alec Baldwin is taking a stand to prevent the potential contamination of water sources in his native New York by hosting a special screening of controversial Oscar-nominated documentary Gasland.

The environmental film highlights the ramifications of natural gas in America's water supply due to the industry's use of hydraulic fracturing, aka fracking, a technique which critics claim can contaminate water from the ground and put air quality at risk.

And the 30 Rock star hopes to raise awareness about the anti-fracking campaign on June 2 when he hosts the What the Frack? event in his mother Carol's hometown of Syracuse.

Baldwin isn't the only celebrity to voice his concerns about the natural drilling technique - The Avengers star Mark Ruffalo and actress Melissa Leo are expected to attend a rally in Albany, New York on May 15 to draw attention to the campaign.
