Paul McCartney says that eating less meat could save the planet.
He proposes a weekly Meat Free Monday, as the livestock industry is apparently one of the most underrated causes of climate change.
"Although more and more evidence is coming to light showing how the growth of the global meat industry is having alarming environmental consequences, the impact of the livestock sector on global warming does not yet seem to have been acknowledged," Paul writes in a letter to world leaders (via UltimateClassicRock). "Encouraging initiatives such as Meat Free Monday would make a considerable difference to the future of the planet."
Meanwhile, Paul has taken part in a charity single alongside other British singing stars to support families from his native town of Liverpool.
In 1989, a tragedy at Liverpool football stadium left 96 fans dead in a crush due to overcrowding. It was recently revealed that police covered up evidence so they could blame fans for the disaster.
Proceeds from their cover of Neil Diamond's "He Ain't Heavy, He's My Brother" will go to the affected families' ongoing legal battle.
