According to the reading passage, the writer shows concerns about the petroleum whose reserve is on decline. To solve this problem, the speaker mentioned three possible solutions to the issue.
Firstly, she argues that if all the auto mobiles that guzzle the petroleum are converted to the behecles that go on alternative energy, the usage of the oil will be drop to a half of the current amount of petroleum usage, which indicates auto as a major culprit of the petroleum running out.
Second, she suggests that world goverment, i.e. the lawmakers, should be aware of this issue and take immediate actions: increaing the price of the petroleum to control its demand. This can be done by either imposing higher tax than now or restrict the amount of the toxic emission. Especially, as the latter way is environmental friendly, there is a great advantage that the earth can be less suffer from the green house effect by limiting carbon which erodes the ozone layers.
Third, she mentioned is that world goverment may offer subsidy to the auto mobile industry so that those companies which are in trouble in making ends meet when it comes to manufacturing cost of the hybrid cars and trucks. This will faciliate the trasition of fuel-guzzling machinery to "smart" energy like alternative fuel, electricity and hydrogen. |
