Hungry mouths, now and in the future--how will our elders fare?

摘要

A report entitled 'Global and Farming Futures' published in January of this year by Foresight, a UK Government think tank, has suggested that there needs to be fundamental changes in food production throughout the world. By 2050, there could be potentially an extra 2.4 billion people to feed with very little extra land on which to grow that food. The report has involved over 400 experts and has considered food production from farming on land and in the sea. It states that the major threats to food production come from climate changes, competition for water supplies, competition for energy resources, and changes to the dietary requirements and choices of the population with a move towards greater meat and dairy consumption.
