This is a new rapid response assessment report released by UNEP warns that up to 25 per cent of the world's food production may become lost due to environmental breakdown by 2050 unless action is taken. The report provides the first summary by the UN of how climate change, water stress, invasion pests and land degradation may impact world food security, food prices and life on the planet and how we may be able to feed the world in a more sustainable manner. The report concludes that we need to get smart and more creative about recycling food wastes and fish discards into animal feed. While major efforts have gone into increasing efficiency in the traditional energy sector, food energy efficiency has received too little attention.
