New Delhi, Dec 13 (ANI): Chocolates could run out by 2020 as the cocoa supplies are diminishing across the world. Industry expert Angus Kennedy said that the chocolate bars may get replaced by slabs of palm oil and vegetable fats packed with raisins and nougat by 2020 as there is a worldwide shortage of cocoa. As the cocoa crops are being replaced by more profitable rubber plantations, the future of chocolate bars looks bleak.
