Variety is the spice of life

September 4th, 2010

Recently I have been reading a number of books around transgenic foods (also known as genetically modified foods), and the dangers/benefits they produce. Whilst this topic is highly decisive, it did highlight for me another area of concern… the twindling number of species grown in our agricultural systems.

For example, over the 20th century, the US Department of Agriculture’s seed storage bank reduced the varieties of fruits and vegetables held. For example 544 varieties of cabbage became just 28; 287 varieties of carrot was reduced to 21; and most staggeringly of all, 2,683 varieties of pear was reduced to approx 300.

Of course the practical upshot of these losses is the fact that the majority of our food crops, both in agriculture & the home garden, are genetically narrow.
