That ’s what the Massachusetts land forester told me – the emerald ash borer is on the loose in southerly Berkshire County where my wife and I have our 130 - acre woodlot and within the next span of years this pest is look to drink down virtually all the native ash tree , or roughly5 % of the forest tree , in this part . In fact , this mortality rate is expected to become general throughout Connecticut , too , and finally throughout southern New England and beyond . And to my idea , it is a serious argument for the creation of GMO plants .

This loss of trees to an introduced Asiatic pesterer is even more grievous in context . My region lost all its American chestnut tree ( as much as 1/4thof the hardwood trees ) to the ravage of an present Asiatic computer virus in the early part of the twentieth century . More of late , it lost most of its hemlocks ( an forecast 6 % of the woods trees ) to an introduced Asiatic insect cuss . If the Asian Longhorn Beetle ever escapes from its modified urban eruption into the woodland in general,73 % of the timberland treesin southern New England would be at peril .

Asian ashes , chestnuts , and other tree which develop alongside the Asian pests have a natural ohmic resistance . American scientist have tried to interbreed these Asian trees with their American relatives to remove the resistance but given the long time it takes a tree to develop from seed to intimate due date , progress has been distressingly dense . A 35 - year cause by the American Chestnut Foundationto breed a immune American chestnut , for instance , has only begun to produce pregnant results in the last few year .
Genetic applied science offer a far more effective fashion to insert genes for pest electrical resistance into the DNA of American tree diagram . This has already been accomplished withAmerican chestnut treesand Dr. Paula M Pijut , a research plant physiologist with the U.S. Forest Service , has been operate onsomething similarfor several species of North American ash tree Sir Herbert Beerbohm Tree in her laboratory at Purdue University . Both of these projects have been accomplished in a prison term scale of years rather than decades . An additional advantage of genetic engine room is that it is potential to bring forth resistant trees that take issue from their American ancestors by only a handful of factor rather than the compromise Asian - American hybrids produce by established breeding technique .
I ’m no sports fan of GMO food , but GMO trees seem to me a far better alternative than a biologically impoverished forest .
