Genetic modification, a process used to change an organism’s genes and hence its characteristics, is now being used to improve trees through genetic modification. It is possible to create trees that produce more fruit, grow faster, or withstand adverse conditions. Planting genetically modified trees on a large scale promises to bring a number of benefits.
First, genetically modified trees are designed to be hardier than nature trees; that is, they are more likely to survive than their unmodified counterparts. In Hawaii, for example, a new pest-resistant species of papaya trees has been developed in response to ring spot virus infections that have repeatedly damaged the native papaya tree population. Planting the genetically modified papayas has largely put an end to the ringspot problem.
Moreover, genetically modified trees promise to bring a number of economic benefits to those who grow them. Genetically modified trees tend to grow faster, give greater yields of food, fruit, or other products and be hardier. This allows tree farmer to get faster and greater returns on their farming investment and save on pesticides as well.
Finally, the use of genetically modified trees can prevent overexploitation of wild trees. Because of the growing demand for firewood and building timber, many forests around the world are being cut down faster than they can be replaced. Introducing genetically modified trees,designed for fast growth and high yield in given geographic conditions,would satisfy the demand for wood in many of those areas and save the endangered native trees, which often include unique or rare species.
The reading and listening materials have a conflict of opinions about the genetically modified trees. The author believes that it's beneficial to humans and nature, Which is contradicted by the following speaker.
First, the author explains that genetically modified trees are hardy and tend to survive unfavorable environmental conditions. However, the professor refutes this point by explaining that it is true that modified trees can be extremely resistant to one condition like parasite or drought but they lake diversity of unmodified trees. According to the professor among the unmodified population, There is always some individual who is resistant to a certain unfavorable condition, Therefore no matter what happens part of the population always survive. This factor is simply not true for modified trees because they are uniform and share common traits.
Second, the author argues that genetically modified trees have economic benefits for farmers for they grow faster and can produce and yield more crops. The professor opposes this by saying that modified seeds are more expensive and farmers have to pay to the producer for each time they plant that seed. Due to this point, the made argument is not valid.
Lastly, the author claims that with using modified trees we can preserve native trees. According to the author because of the growing demand of woods especially fire and timber woods, Many forests around the world being cut down faster than they can be replaced. Modified trees can prevent this overexploitation for they grow fast and can replace unmodified trees as a source of wood. However, the speaker refutes this by explaining that modified trees have an aggressive growth and therefore compete with unmodified trees for nutritive materials. This competition would result in a wipeout of unmodified trees.
