A principle that is used extensively in engineering systems,redundancy,in effect,says don’t put all your eggs in one basket.Nature itself uses this to create diversity in all plant and animal life.
Given this universal principle, it is amazing that the fever for globalization has been recklessly adopted by many richer countries.Their use of GMO foods is a good example which destroys the diversity of plant life leading to many suicides among farmers in India.
I think globalization to ensure profits for big corporations is a great danger and could lead to a catastrophe that Rumsfeld called “unknown unknowns”.
In effect,we must create a firewall so that local economies can thrive without exposure to the vagaries of the global markets.That will be our protection.
