Water Quality
Successive changes in and around Manila Bay are largely due to the intertwining impacts of continued industrialization, unrelenting increase in population, and the incessant human activities catering to livelihood and habitation. These factors are directly degrading the overall environment of Manila Bay and these impacts are manifested in the continued deterioration of the water quality within the bay. Several industries operate along the bay in the highly urbanized Metro Manila area, while there are shipyard facilities in Cavite and in Bataan, several more heavy industries, refineries and a power plant are present. At the shipping ports and ferry terminals, an average of 30,000 ships arrive and depart annually to transport passengers, manufactured goods and raw materials. Industrial waste discharges and discharges of untreated domestic wastes from drainage and sewer outlets have contributed to the severe decline in the quality of water and sediments in the bay as well as impacted on the existing marine habitats.

Famous quotes containing the words water and/or quality:
“What a dissimilarity we see in walking, swimming, and flying. And yet it is one and the same motion: it is just that the load- bearing capacity of the earth differs from that of the water, and that that of the water differs from that of the air! Thus we should also learn to fly as thinkers—and not imagine that we are thereby becoming idle dreamers!”
—Friedrich Nietzsche (1844–1900)
“The irregular and intimate quality of things made entirely by the human hand.”
—Willa Cather (1873–1947)
