Facts about Seas and
Oceans:
-
Oceans cover 70 percent of
the Earth’s surface and more than 90 percent of the
planet’s living bio mass is found in it.
-
Three-quarters of the
world’s mega cities are by the side the sea. Forty
percent of the world’s population lives within 60
kilometers of a coast, which by 2010 will increase
to 80 percent within 100 km.
-
Plastic waste kills up to
1 million sea birds, 100,000 sea mammals and
countless fish each year.
-
An estimated 21 million barrels of oil run into the
oceans each year from street run-off, effluent from
factories, and from ships flushing their tanks.
-
Less than one half a
percent of marine habitats are protected compared
with11.5 percent of global land area.
Save the Seas and Oceans
and thus save the Mankind
Our agenda is to give a human
face to environmental issues: empower people to become
active agents of sustainable and equitable development;
promote an understanding that communities are pivotal to
changing attitude towards environmental issues; and
advocate partnership which will ensure all nations and
peoples enjoy a safer and more prosperous future, thus
World Environment Day is a people’s event with global
participation.

Water: Natural resource of
human life
Many cities in developing
countries are growing so fast that they cannot manage
the water supply. In developing countries including
India, as much as 70 percent of the water pumped in to
cities is lost before it can reach consumer, leaking out
of faulty water mains, pipes, and faucets (Warner, D.,
1998). According to National Commission for Integrated
Water Resource Development Plan, it is estimated that
the volume of India’s annual usable water resources is
approximately 1,086 km3. The current demand is around
600 km3 and by 2050 the demand estimated to be 1180 km3!
Utilization of piped water and water requirement found
to be more in densely population areas and
Industrialized areas, leaving agricultural land which
mostly depends on rain and river water. Demand and
supply of water in four Metros is given in Table 1.
Table 1 explains water situation in selected mega cities
in India. But as 80 percent population lives in RURAL
areas, many questions would arise that How to manage
water for India’s Population? What would be their
requirement? And where is the source?
It was found that 66 percent of water resources from the
rivers Ganga- Brahmaputra system accounts for 33 percent
of Indian area. The rest has to depend on rivers, which
flow in monsoon season and dry during other times.
Scanty rains and dry rivers will add up the problem of
water scarcity Experts suggests that: water management
can be done by (1) Linking and preserving large water
sources (Ganga-Cauvery link),(2) Storing ground water
and trapping rain water (watershed management, drip
irrigation etc), (3) Reducing consumption of water
(counseling and education of water management) and many
more. Save water-save life.
