The fastest growing trees in the world...but...!

Are these the fastest growing trees for timber in the world and what are the disadvantages if any! Genetically modified trees. GM trees, this is not #agroforestry - #TreeNews documentary. These eucalyptus trees or gum trees are modified to grow faster. Genetically engineered to produce timber quickly. GM trees and monoculture forests threaten native species from cross pollination and are a wider threat to the environment and biodiversity. A genetically modified tree (GMt, GM tree, genetically engineered tree, GE tree or transgenic tree) is a tree whose DNA has been modified using genetic engineering techniques. In most cases the aim is to introduce a novel trait to the plant which does not occur naturally within the species. Examples include resistance to certain pests, diseases, environmental conditions, and herbicide tolerance, or the alteration of lignin levels in order to reduce pulping costs. Genetically modified forest trees are not yet approved ("deregulated") for commercial use, with the exception of insect-resistant poplar trees in China. and one case of GM Eucalyptus in Brazil. Several genetically modified forest tree species are undergoing field trials for deregulation, and much of the research is being carried out by the pulp and paper industry, primarily with the intention of increasing the productivity of existing tree stock. Certain genetically modified orchard tree species have been deregulated for commercial use in the United States including the papaya and plum. The development, testing and use of GM trees remains at an early stage in comparison to GM crops. https://en.wikipedia.org/wiki/Genetic... Creative commons    / @stayfrostie1632
