Supply chain is where its all falling to pieces. Multiple issues worldwide feeding into it.Australia farming as good as can be,but world wide is a different matter,and food is a weapon.
Let's not forget that this is an engineered crisis.supply chain collapse is not due to covid but covid measures.
Same for fertiliser shortage,oil price etc no physical cause or hardly but political and geopolitical move.
Most famines are due to man made crisis and this remain true,and i am not talking CC here but war, governments decisions
