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.
The major topic discussed by both the reading and the lecture is analyzing the feasibility of using box-shaped devices to combat desertification. The passage presents the view that, these devices will not be useful to fight desertification and provides three major reasonings for its claim. However, the orrator of the lecture is quick to point out that there are some serious flaws with the writer's claims. In fact, the professor believes these devices are worthy of their use, and addresses, in detail, the trouble with each point made in the reading text.
First of all, the passage posits that the use of such devices is not economically feasible and when added with the cost of equipping such devices into millions of trees, the entire process becomes a huge economic burden which cannot be beard by many countries. The lecture, however, refutes this claim by illustrating the possible re-use of the device once the younger tress get bigger, which will prove its economic efficacy. She goes on to say that when the cost of device is divided by the number of tress it can be re-used upon, then it will in fact prove to be much cheaper.
Secondly, the passage argues that local people living in desertified areas will not be properly motivated in order to install and maintain the devices, primarily because of their poor and arduous living conditions. Again, the speaker counters this stance, by illustrating the secondary rewards of the devices, which may in fact provide incentives for its use. After installation, the device will provide tangential rewards like water collection for growing vegetables and firewood from the branches of larger trees. So, the locals will consent to the use of the equipment.
Finally, the passage warns that once the trees outgrow the small devices, it will not be able to withstand the harsh desert conditions on their own. Not surprisingly, the lecture takes issue with this claim by contending that with the help of the devices, tress will be able to grow long roots capable of reaching the deep moist water sources. She goes on to provide evidence from Sahara desert, where 90% of the trees are still alive even when the devices where removed two years ago.
