Employees walk on a bridge towards the Viterra Inc. Cascadia terminal, owned by Glencore Plc, on Burrard Inlet in Vancouver, British Columbia, Canada, on Tuesday, Sept. 29, 2015. Glencore Plc is considering selling a minority stake in its agriculture business as part of the Swiss miner and commodity trader's wider plan to reduce its $30 billion of debt by about a third. A sale would mark a retreat by Glencore, less than five months after saying it sought to expand in agriculture following the success of its C$6.1 billion ($4.6 billion) purchase of Canadian grain trader Viterra Inc. in 2012.
