If the world’s richest 1 percent started giving 10 percent of their income or 2.5 percent of their net worth to philanthropic projects, it would increase philanthropic spending by at least $3.5 trillion in the first year alone, a report from London-based Longview Philanthropy, a project of the Effective Ventures group, estimates. The report, What if the 1% gave 10%?  (52 pages, PDF), argues that such a boost would make it possible to ensure that no one lives in extreme poverty for the year ($258 billion), prevent the next pandemic ($297 billion), double global spending on clean energy R&D though 2050 ($662 billion), quadruple nuclear security funding ($6 billion), increase AI safety funding tenfold ($1.5 billion), ensure that everyone has access to clean water and sanitation once and for all ($1.22 trillion), end hunger and malnutrition ($341 billion), give women control over their reproduction and reproductive health ($175 billion), massively suppress or eradicate tuberculosis, malaria, and HIV ($219 billion), massively suppress or eradicate most neglected tropical diseases ($53 billion), and halve factory farming by 2050 ($222 billion).
