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 article introduces one way proposed to stop desertification. A box-shaped device that helps in growing young trees. The author makes three points against this idea, but the lecturer argues against each of them with valid reasonings.
First, the passage points that based on the amount of boxes needed to fight desertification, and the high price of each device some countries may be incapable of affording them, but the lecturer argues that, after the tree is grown the device can be removed and then used to grow other trees. The device can be deployed at least twenty more times, making it a lot less txing for the countries in need to afford them.
Second, the author says that local people are called upon to install and maintain the devices, but in most cases the locals live and work in harsh conditions and would not be motivated to do such jobs without any rewards. The lecturer discusses ways to encourage the locals into maintaining the devices, saying that there can be benefits like local families using the water gathered by devices to grow their own small fields, and using the branches of the grown trees as fire wood.
Third, the passage brings to attention that the devices ability is limited to conserving a small tree but the lecturer points out that the matured trees can survive without the device due to developing long roots, pointing out that 90 percent of trees grown in Sahara desert survived and are thriving even after two years of device removal.
