As reported by AFP,
President Benigno Aquino ordered all Earth Day events be held on Monday because most Filipinos would prefer to commemorate Good Friday, a national holiday, his chief aide said on Wednesday.
And anyway, Good Friday comes once a year. Every day should be Earth Day, right? Every day, sure, except this Friday, when I’ll be doing my very best (as poor as that is) to to adhere to the day's fasting and abstinence expectations—which in itself is a good way to reduce my ecological footprint—as well as spending time adoring Christ and praising Him, for by His Holy Cross, He has redeemed the world.
