Anna Oposa directs her creativity and
enthusiasm to protect marine biodiversity
and resources in the Philippines. At the very
young age of 23, Anna co-founded the NGO
“Save Philippine Seas”, hoping to mobilise a
generation of Filipinos that care about the
future of their country. Anna uses her
charisma to passionately push people to
come together and change their
behaviour. Her dedication to the
conservation of the Philippine marine
environment has resulted in grassroots
interventions, media and public campaigns,
and multilateral negotiations on wildlife
trade. Because shark conservation holds a
special place in her heart, in 2012, she
spearheaded the first shark and ray
sanctuary in the Philippines. Anna also
started a programme to empower youth to
become leaders in conservation. Today,
there are already 250 alumni tackling
conservation issues and inspiring others in
all 10 Southeast Asian countries.

Estuaries and intertidal zones supply
essential foods for all living things. The living
or biotic factors like plants, animals, and
microorganisms affect the ecosystem that
includes coral reefs, salt marshes, mudflats,
rocky shores, and mangrove forests.
Estuaries filter out sediments and pollutants
from rivers and streams before they flow into
the ocean, providing cleaner waters for
humans and marine life. On the other hand,
the intertidal zone acts as a nursery ground
for many deep water marine species,
providing both shelter and food during the
vulnerable early life stages for many
organisms. Intertidal species are a critical

Seventy–five percent of the Earth’s surface
is composed of aquatic ecosystems. They
help in maintaining the ecological balance
and home to many organisms that can be a
source of food and raw materials for
humans. The aquatic ecosystems are our
estuaries and intertidal zones. Specifically, it
comprises all our coral reefs, salt marshes,
mudflats, rocky shores, and mangrove
forests. Since we get so much from these
ecosystems, which are abundant in marine
life and other resources, their destruction
would largely affect the community that
depends on them. Some of our estuaries
and intertidal zones have already been
destroyed due to industrialization, and most
of the remaining are already under threat.
So, one should learn the value of these
ecosystems and how we can conserve and
protect them.

new skills No. 2
Look at the two pictures. Which of these
pictures show a healthy body of water and
which shows an unhealthy one? What do
you think are the factors that can lead to the
destruction of these bodies of water? How
can we maintain them to be clean, pristine,
and thriving ecosystems? Why do we need
to protect and conserve these ecosystems,
including our estuaries and intertidal zones?
Intertidal zones and estuaries are examples
of bodies of water which are home to
various life forms such as fishes, sea
grasses, sea stars, crabs, shrimps,
seashells, mangroves, sea urchins and
others. An intertidal zone, commonly known
as seashore or coast, is where tides are
observed. This area within “tidal range” is
covered with sea water during high tide and
exposed during low tide, thus named
“Intertidal Zone”. An estuary, however, is a
body of water in which sea water meets with
fresh water. It connects rivers to the sea.

plants and animals and provide food,
medicine, and other products. They also
serve as a breeding ground and nursery of
young aquatic animals. They also protect us
from big waves, strong winds, and even
during storms. They also serve as the exit
points of water during floods. Estuaries filter
salt from the sea water. These areas also
give significant contributions to tourism,
agriculture and fisheries, and our economy
as a whole. Because of its importance, we
should take care of these bodies of water.
We need to protect and conserve these
places. As a youth, you can do simple things
at home and in your community to help
these ecosystems, such as properly
disposing and segregating our garbage and
other waste materials. You can also telland
encourage your parents and neighbors to
use organic fertilizer, grow plants that need
less water, help in the clean-up activities in
your barangays on cleaning these places,
and encourage classmates and friends not
to disturb animals and plants in their natural
habitat. Putting coconut fiber mat, planting
marsh grass and mussels’ bed are some
activities that can protect our estuaries and
intertidal zones. There are still other ways
we can do to help our environment. Can you
think of some? Moreover, sustaining the
balance of these bodies of water is also a
significant factor that we can do as stewards
of Mother Earth. We should avoid some
practices that would contribute to the
destruction of estuaries and intertidal zones.
Industrial pollution, overharvesting of aquatic
species, dredging, draining and paving over
estuarine waterways, oil spills, and
population growth in coastal watersheds are
some threats to estuaries and intertidal
zones. Thus, in order to conserve and
protect these, let’s help one another and do
our part as good citizens and guardians of
God’s creations.
