A major symposium on the the global impacts of UK food consumption. Food for humans and conservation are in conflict. The challenge for humanity is how is to produce more food for more people on less land and with less environmental impact. Feeding people should not come at the expense of biodiversity. Even if everything remains unchanged, the struggle will be to provide enough food for the human population because of climate change, urbanisation and land degradation. The number of mouths to feed is expected to have increased in 2050 by two billion. Demand for improved food quality will also grow as more people move out of poverty. How can the food demands of a larger global population be met without further loss of biodiversity? The need for far-sighted action is imperative to ensure that supplies of food for people and animals are to be produced sustainably.
