GM'd bananas are approaching extirpation.

Yes. We'll have no bananas!!! - Thanks to Selective Breeding (Guild Wars2 Gold), our Favourite Fruit can Neither Reproduce nor Defend Itself from Disease

The banana is about to disappear from store shelves around the globe. Experts say the world's favourite fruit will pass into oblivion within a decade. No more fresh bananas. No more banana bread. No more banana muffins or banana cream pie.

Why? Because the banana is the victim of centuries of genetic tampering. Scientists say they will be unable to prevent the extirpation of the banana as an edible commercial crop. And its demise may be one more powerful argument in the hands of those who are concerned about genetic modification of foods.

The banana's main problem is that it has become sterile and seedless as a result of 10,000 years of selective breeding (Guild Wars2 Gold). It has, over time, become a plant with unvarying genetic sameness. The genetic diversity needed to cope with environmental stresses, such as diseases and crop pests, has long ago been bred out of the banana. Consequently, the banana plantations of the world are completely vulnerable to devastating environmental pressures.

According to Emile Frison, newly appointed director-general of the Rome-based International Plant Genetic Resources Institute, science is helpless to prevent the demise of the banana. Already, he says, as much as 50 per cent of the world's banana harvest is lost to insects and disease.
