This is where it gets serious. It is estimated that we currently have seven billion on the planet. The UN estimates that the population will continue to grow to at least nine billion, maybe ten billion. If you just think for a moment what that means – when I was born, 50-odd years ago, there were about two billion people on the planet. So, within my lifetime it’s gone from two to seven and certainly before my children are my age it will be nine or ten. How are we going to feed these people?
