Diversity and differentiation are a function of complex systems.
We need to learn to value the importance of diversity. However we look at the world, a loss of diversity will be our loss. Reliance on GM or a few carefully bred varieties makes us more vulnerable. After a huge extinction (probably including ours) great new opportunities would arise for new adaptations. A new equilibrium would eventually be reached.
Can we conserve the gene pools, rare breeds and plant seed banks, saving and developing old varieties of fruit and vegetables especially legumes, to help increase our chances of a sustainable life style.
