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.
First, at a cost of 25 U S. dollars each, the device would make growing trees a prohibitively expensive process. Meaningful efforts to fight desertification involve growing millions of trees. Some countries most affected by desertification cannot afford to buy devices for millions of trees
Second, plans for fighting desertification involve asking local people to install and maintain the devices. People living in some of the areas most affected by desertification work long days in harsh conditions: sometimes barely managing to provide food for their families. It would be difficult to motivate these people to look after trees that cannot serve as a source of food for them.
Third, the device's ability to collect and conserve water is limited. Each one provides only enough water to keep a small tree alive. Trees that have outgrown the device have to deal with unforgiving environmental conditions on their own. In some places where the devices are being tried, six months can pass without a drop of rain. Once the trees become too big for the device, they may not be able to survive in such a harsh environment.
Both reading and the lecture revolve around the repercussions of using a box-shaped device to collect water and avoid desetification in arid habitats. The writer provides evidence that the proposed device is not profitable enough and have strong downsides while the lecturer find his ideas dubious and cast doubt on the reasons mentioned in the paragraphs.
Firts, the author states that the box-shaped devices are too expensive for growing millions of trees to avoid desetification. In contrast, the orater holds the view that these gadgets are reusable for more than twenty times. She adds that whenever a tree grows and the box becom small for it, the users can remove th tree from the box and replant another tree in it. So when we devide the cost of device into number of growable tree, it is economically reasonable.
Second, the article assets that local people in desert areas are work realy hard in harsh environments and they can not even provide enough food for their family. Therefore the chance of convincing them to use these boxes is low. On the contrary, the speaker claims that these devices can also provide water for other products like as vegetables and by doing so, the farmer not only can avoid the desetification but also can provide more food for his family and this is a temting motivation for them.
Furthermore, the writer mentions that the device's reserviour is quit limited and it can only help small trees to stay alive. He also points out that whenever the trees become mature and the users remove it from the device, the trees can not resist the arid enviroment and die. Conversely, the speaker throws out a challenge to this argument by asserting that during the time that the tree is depenent on the device, its root can grow and reach down to the moist soil. So eventually, they can also survive without the device and the mentioned reason, like all aforementioned ones, is unconvincing.
