On fuel price hike

I have two questions concerning articles that appeared in The Jakarta Post on March 1 concerning the fuel price hike: The article concludes with the statement that alternate forms of fuel should be used to offset the burden of price hikes.

It seems to me that the author should name a few those fuels that will take the place of petroleum-based energy.

Concerning the article that states a buffer zone of trees to prevent a future tsunami: How can that be? A tsunami is an act of nature, over which man has no control. PATRICK MORGAN Jakarta
