Big Sean just launched a major fundraiser to help the children of Flint, Mich., and then donated some big bucks to help get it started. The 27-year-old rapper launched a CrowdRise campaign called #HealFlintKids in response to the city's water crisis that has lead-contamination and is threatening the entire community's health, according to Billboard.

While some people are dealing with immediate physical health problems, there are also developmental issues linked to lead poisoning in children, so he's hoping that with the help of his campaign, the money he raises can go toward the Community Foundation of Greater Flint Michigan's "Flint Child Health & Development Fund."

"I'm raising money to support the kids of Flint Michigan. Toxic water in Flint has rendered the water undrinkable and put the entire city in a state of emergency. Flint's children were hit the hardest and some have experienced permanent and potentially devastating health defects from lead poisoning," Big Sean wrote on the official fundraiser's website. "We know the needs of Flint children exposed to lead, particularly those most vulnerable-children ages 0-6-are ongoing and long-term. You can be assured that your gift will be used for critical interventions today and well into the future. The Sean Anderson Foundation is raising funds on behalf of the Community Foundation of Greater Flint Michigan. Please give what you can, every donation counts. Thanks so much for your support."

Big Sean, born Sean Anderson and a Detroit native, started off the donations by contirbuting $10,000 himself, according to TMZ. He is also encouraging fans to donate by offering up some fan experiences to those who donate more than $10. He will be giving five of those people a chance to win a meet and greet, photo op and VIP tickets to one of his concerts during his tour this year.

He also tweeted about the issue, asking for an explanation of the crisis from Michigan Governor Rick Snyder.

"Flint I love you, Im sorry you have to deal with this tragedy! This is a state of emergency n I have been seeing how me n my family can help," he wrote. He added, "This is not a natural disaster, this is not a mistake, this is clearly some real dirty work going on! Unacceptable! Explain Governor? #Flint."

Rapper Meek Mill has donated 60,000 bottles of water to Flint, according to Music Times. 50 Cent has also taken part in the cause by donating $50,000.
