Only with the advent of molecular genetics did people realise how precious the genetic heritage is. Kew Gardens got a £40m grant to establish a world gene bank to store hundreds of thousands of seed varieties. Of course this isnot done for conservation purposes - that would only be by planting and growing - but for the genes themselves. One example in Switzerland of loss of a genome is the Fribourg cow. It was just thrown away by traditional breeders after it was bred for hundreds of years. People would not let this happen nowadays.
