food sustainability

I am hugely frustrated. Frustrated by a species slow to grasp new concepts, content to doggedly hold on to the status quo, with a terrifyingly strong grasp.
With rising populations creating more mouths to feed, newly affluent citizens in developing countries hungry for meat and other resource-intensive foods, growing global water stress and changes in climate, agricultural supply chains are facing unprecedented pressure.
Sainsbury's is the UK's third biggest supermarket chain and are primarily a food company - food accounts for over 70% of their sales. Yet they are keen to build over farmland at a time when people are increasingly concerned about how enough food will be produced for the growing populations of the future.
With the world's attention slowly but surely turning to the oceans and with advocates like the Prince of Wales who offer solid, pragmatic and realistic cases for change, perhaps a bright future is nearer than we think.
