Because of climate change, more and more land that was once used to grow crops or provide food for animals is turning to dry, unusable desert land. There are many proposals about how to stop this process, known as desertification. A number of proposals involve growing trees, because trees can help protect soil and provide many other benefits to fight against desertification. Some scientists have proposed that the best way to grow trees in dry areas in danger of desertification is by using a box-shaped device surrounding the young tree. The device collects water that condenses from vapor in the atmosphere and helps the tree to grow. However, other scientists believe that this device will not be successful in fighting against desertification for the following reasons.
Desertification is a phenonmenon which is attributed to the drying of land where it cannot be used for cultivation anymore. The reason for this phenomenon is climate change and scholars have proposed measurements to counter it. Planting trees in dry areas with the help of box-shaped devices that has the ability to accumalate vapor from atmosphere is a technique that has supporters and critics. The text proposes three reasons why it cannot be implemented effectively, while the professor opposes the text.
First, the boxes used for growing trees is not affordable right now. The price of each box is 25 dollars which is not affordable by most people who have been harmed by destertification. The professor casts doubt on this idea by saying that these boxes have the potential of being used for more than 20 times. Hence, according to him, they are more cost-effective than the text claims.
Second, the people who are effected by desertification do not generally have enough resources or time or are not willing to practice this activity on trees that do not provide food. According to the lecturer, not only can this process help people in acquiring food but also for other needs such as firewood. Accroding to him, people can use the branches on trees for fire or grow trees or vegetables that provide food.
Third, the text challenges the ability of this technology to maintain water. Although this device can help young trees to grow, when they are bigger this device can no longer help in their growth. However, the lecturer says that this device can help young trees to grow its roots and reach water-rich deep soils. He gives an example from Sahara desert where young trees have survived the harsh conditions even after 2 years of the box removal.
