there is no question that pollution is a big problem in the air and the water its so bad i would not eat any fish that were farmed because the lake is so bad you can not see your had in the water stay away from the fish in the Philippines
and the air is stinks in manila, makati and baguio city very bad i would only ad typhoons and earthquakes to the list
even though i live in a typhoon prone area we dont get as many as the Philippines and we build to hurricane building codes
needless to say most of the Philippines does not except the high rises
