This guy is bat crap crazy or/and evil.
Two problems: One, if the Filipinos don't let people invest in our huge natural gas deposit in the West Philippine sea, China is there to take it over (indeed, they have been blocking the Philippines for two years by claiming they own it, despite international law that denies their claim).
The second problem? It will hurt middle class and poor people. Tricycles (motorcycle side cars used as a local taxi), jeepneys, etc will cost more, as will buses and trains. So commuting to work will cost more.
Cooking with LPG (i.e. propane) will be too expensive (they'll have to use wood, which causes a lot more pollution).
And of course the price of food will skyrocket: Fertilizer is already gone up (even our organic fertilizer has doubled in price), the cost of using a handplow (cultivator to prepare fields for rice), thresher, harvester, rice drier, etc will go up because they use diesel. And of course, the price of shipping our rice to Manila will go up.
But hey, poor people don't have to eat do they?
And then the bishops wonder why so many in the Philippines are joining other churches that stress Jesus rather than ecology.
IIRC, the Old Testament has something to say on the matter.
