The initiative, which has teamed up with the charitable organization Drop4Drop, aims to address the current clean-water crisis—663 million people don't have access to clean water close to home and 1,800 children under five die every day from clean water-related causes.

"I am proud to support Drop4Drop and their work to help address the World Water Crisis," said Delevingne.

Experts have estimated that it would cost $10 billion to remedy the water crisis worldwide, which is about the same as what Americans spend on tea each year.

"Awareness is crucial," said Drop4Drop's co-founder Lucas White. "We are working to address this crisis, and are confident that the support and visibility we are generating online today will encourage big corporations and businesses to come alongside us and fund our crucial work in the communities that need it most."
