Unsafe Drinking water
1. Unsafe Drinking Water
• Because of our love for and dependence on the
water, many Filipinos are settling down on
estuaries.
• Estuaries concentrate pollution may caused by
waste waters from urban areas or dumping of
toxic waste containing agricultural pesticides
and fertilizers.

2. Loss of Economic Resources
• The economy of many coastal areas relies on the
natural beauty and bounty of estuaries. When
those natural resources are imperiled, so are the
livelihoods of the many people who live and work
along the coast.

• "Red tide" is a common name for events where
certain algae containing reddish pigments "bloom"
so that the water appears to be red.
• Effects of Algal Bloom on Human Health

Red tide in Xiamen, in China’s Fujian Province, April 21, 2007.
Red tides are nutrient-fueled blooms of phytoplankton that
discolor water with their pigments. Several species are known to
have toxic effects on marine life and pose a risk to human health
through the consumption of exposed fish.

Reduction of Fisheries
4. Reduction of Fisheries
• Upstream water diversions and damming (for irrigation,
hydropower, flood protection, etc.) have resulted in
changes in the quantity, rate, and timing of freshwater
flow and the reduction of sediment and nutrient
discharge into estuaries. Overall effects can range from
increased coastal erosion because of reduced sediment
input to reductions in commercial fishery species because
of increases in estuarine salinity.

• Wetland loss and degradation have
amount of habitat available to support healthy
populations of wildlife and marine organisms. The
clearing of land to obtain timber, the construction
of homes and roads, and other development
projects completed without properly vegetating
the area can lead to excessive sediments being
washed into the estuarine environment.
