The writer of the reading passage and the lecturer talk about the harmful gases emitted from people’s living. The writer suggests the three negative effects of the gases while the lecturer raises specific counterclaims. To begin with, the lecturer argues that the technologies can maintain crop yield, giving an example, GM plants, which are growing plant in dry area. This is in complete opposition to the point of the reading passage, stating that these poisonous gases effect planet warmer and arid, so the gases have a negative effect on the agriculture. Furthermore, the second assertion, that CFCs emitted from refrigerators and air conditioners have an influence on people’s skin cancer is refuted by the lecturer. The lecturer explains that developing cosmetic items can resolve the problems. The lecturer explains that one of cosmetic companies has made a sun cream which protects people’s skin from the sun for over six hours. Finally, regarding to the last point about the economic loss, the writer states that the toxic gases with acid rain corrode building, so it can be economic burden on people. The lecturer, however, contends that there are solutions to address the problems. Developing paints can preserve the building from rain and actually one of companies succeeded in using the paint. |
