Oscar-winner Ben Affleck has announced he will live on just $1.50 a day as part of the Global Poverty Project's Live Below The Line campaign. The Argo director is following the lead of Hugh Jackman, who successfully lived on the same amount for the campaign in 2011, reports the Los Angeles Times.

Affleck - a long-time charity campaigner - took to Twitter to show his support. "1.4 billion people live on less than $1.50/day. I'm joining Live #BelowTheLine on behalf of @easterncongo. Will you?," he tweeted. The challenge is meant to "give a glimpse into the lives of 1.4 billion people who have no choice but to live below the line every day - and who have to make $1.50 cover a lot more than food," according to the organizaton's website.

Jonah Hill, Katie Couric and Justin Bieber's Scooter Braun also tweeted their support for the case, while musician Josh Groban has raised $4,700 so far after commitment to spending just $1.50 per day on food and drink. "In today's world, extreme poverty and inequality are unjustifiable and unfair. Live Below the Line demonstrates the problem in a concrete way, while raising money to address the problem." Thor: The Dark World actor Tom Hiddleston posted a video of himself on his fifth day of the challenge. The clip shows Tom in his kitchen with a simple baked potato for lunch. He also tweeted his meals throughout the challenge, which included boiled rice with vegetables, and an omelette with kidney beans. "Profoundly aware that to live truly #belowtheline I would have to forego many & various privileges....," he tweeted in April, adding, "To live truly #belowtheline I would have to surrender the roof over my head, gas, electricity, and clean, running water."

Could you survive on just $1.50 per day? Of course you could. Give it a try.
