Feeding the world is a problem of economics and politics, not the ecological problems of growing food.

There is huge capacity for food production in the world, and no reason anyone should go hungry

Keeping people hungry is deliberate economic policy.

In New Zealand where I live we make enough food for millions more than live here, yet many face food insecurity.

As I say, it is deliberate, calculated, government policy to keep people on the edge of hunger.

It keeps wages low - our idiot business people think every dollar paid in wages is a dollar of profit lost

Idiotic and cruel, and widespread

Of course it's a political problem. So what are we going to do? Sit around and pray for a miracle that solves all of politics? Meanwhile people are suffering. Increasing efficiency of food production will actually create more food, which makes it cheaper, which makes it easier for people to get. That we can probably actually accomplish, unlike solving politics.
