Noisy Scrub Bird,
I agree with Yabby to some extent, I don't like to see foreigners buying our good farming land and as he said there is ample super funds being invested offshore that should be used here.

But on the global food shortage, we should be encouraging contraception, especially in those countries that are subject to famine, If Iran can dramaticly lower their birthrate by education then so can other countries. The vatican should come to grips with the world overpopulation.

Closer to home, I think the continued encrouchment of urban areas on our agricultural land as a big problem. All our major cities were founded near good land and it is being covered with concrete, bitumen and houses. Farmers are being forced onto more marginal land. We need to look closely at our population growth and cut our immigration rate.

I see there is some concern about various additives and chemicals being added to imported foods, especially from China. Maybe a good scare may get people buying Aus grown produce again. Frankly I wont buy imported veges or seafood, and it is difficult to buy local canned fruit now. You can forget about local ham or tuna in cans.
