And the charity of billionaire Microsoft founder Bill Gates and his wife Melinda is under criticism following the disclosure it’s substantially increased its holdings in the agribusiness giant Monsanto to over $23 million. Critics say the investment in Monsanto contradicts the Bill and Melinda Gates Foundation’s stated commitment to helping farmers and sustainable development in Africa. In 2007, the Gates Foundation said it would review its holdings after a lengthy exposé in the Los Angeles Times revealed it had invested nearly $9 billion in companies whose practices run counter to the foundation’s charitable goals.
