Elon Musk’s wood-chipping of the United States Agency for International Development (USAID) is poised to leave piles of bodies behind in its wake, a new study suggests. Scientists have calculated that recent funding cuts to USAID could lead to millions of preventable deaths worldwide over the next half-decade.

New research published in the journal The Lancet warns that cuts to the U.S. Agency for International Development could result in 14 million deaths over the next five years.

The analysis, published in the Lancet, estimates the agency’s programs saved 91 million lives worldwide over two decades, playing a vital role in global health.
