Size: 5th largest planet in our solar system.
Surface Area: 197 million (197800000) square miles.
Land: 57 million (57300000) square miles(29%)
Water: 139 million (139500000) square miles(71%)
Diameter: The Earth has an average diameter of 12,742 kilometers.
(7,926 miles)
Average Temperature: The temperature at the Earth's core is
estimated to be between 5000 and 7000 degrees Celsius.

5. Earth Fact
Thehighest temperature = 58 CatAL-Asisiyah, Liaya
The lowest = -89 C at Antarctica
Length of Year: 365.25 days
Inclination of Axis: The Earth's axis has a tilt of about 23
degrees. It is this tilt which causes the seasons.
Chemical Composition: The Earth is made mostly of iron, oxygen,
silicon, magnesium, nickel and sulfur: 34.6%Iron, 29.5%Oxygen,

8. Biodiversity
What is Biodiversity?
"The variability among living organisms from all sources
including, inter alia, terrestrial, marine and other aquatic
ecosystems and the ecological complexes of which they are part;
this includes diversity within species, between species and of
ecosystems."

10. Biodiversity and Human
It is widely accepted that the world is losing biodiversity as a
result of human activity. This is generally regarded as a negative
trend as biodiversity provides a number of important
benefits:
11. Science and Medicine - Many important drugs have been
synthesised from chemicals found in plants. High levels of
biodiversity maximise the selection of plants that scientists can
screen for potential new drugs.10
12. Biodiversity and Human
13. Ecosystem - Human activities that impact negatively on
biodiversity can have a disproportionately large impact - e.g. due
to the effect on animals further up the food chain. 14. Cultural
and Aesthetic Value - The unmeasurable value of experiencing the
world in which we live and helping to preserve it. 11
15. Biodiversity of Pakistan
Pakistan has 225 Protected Areas (PAs),
14 national parks,
99 wildlife sanctuaries,
96 game reserves.
Pakistan covers a number of the world's ecoregions, ranging from
the mangrove forests stretching from the Arabian Sea to the
towering mountains of the western Himalayas, Hindukush and
Karakoram.

16. Biodiversity of Pakistan
The country lies at the western end of the South Asian
subcontinent,
Its flora and fauna are composed of a blend of Palearctic and
Indomalayan elements, with some groups also containing forms from
the Ethiopian region.

18. Pakistan in the sandwich of Ecozones
The country lies at the western end of the South Asian
subcontinent, and its flora and fauna are composed of a blend of
Palearctic and Indomalayan elements, with some groups also
containing forms from the Ethiopian region.

19. Ecological zones of Pakistan
Pakistan is divided into 9 major ecological zones.
WWF - Pakistan is working to conserve the environment through its
Target Driven Programmes (TDPs) that address issues pertaining to
samples of forest, freshwater, marine ecosystems, species, toxics
and climate change.
The emphasis is on conserving representative sites of ecologically
important areas within these Target Driven Programmes. Conservation
of desert ecosystems is included under forests.

20. Ecological zones of Pakistan
In most of its projects, WWF-P supports local community initiatives
to conserve natural resources, and helps look for ways to improve
community livelihoods.
Almost all conservation projects have the following common features
and priorities: partnership with local bodies and capacity building
at all levels from local communities to government bodies.

21. Critical Ecosystems of Pakistan
Under the Global 200, ecosystems have been ranked to carry out
conservation through comparative analysis. It covers all habitats
on the land masses and in the ocean. The Earth has been divided
into 238 ecoregions, by the United Nation, the National Geographic
Society with WWF. Out of them 5 are in Pakistan. The Global
ecoregions of Pakistan are:
Rann of Kutch flooded grasslands
Tibetan Plateau
Western Himalayan Temperate Forests
Indus Delta Ecosystem Arabian Sea

23. Mangrove Forests
Pakistan, houses the worlds 5th largest continuous mangrove
area,
Known as the Indus delta mangrove ecosystem,
Its stretched over some 600, 000 hectors between Karachi and the
south-western border of India on the coast of Arabian Sea.
Beside mangrove forests, the delta also includes creeks, extensive
mud flats, sand dunes and salt marshes.
An estimated 135,000 people abound the area, earning their
livelihood mainly from fishing besides camel browsing, buffalo
grazing and wood collection etc.
20
24. Mangrove Forests
The over fishing, reduction in sweet water flow through the Indus,
pollution and changes in hydrography is dangerously degenerating
the mangrove vegetation and habitat.
The need to conserve and rehabilitate the valuable resources of
this ecosystem has resulted in formulation of the Rehabilitation
and Replanting of the Indus Delta Mangroves (RRIDM) sub project in
1993.
The project has succeeded in establishing about 16000 hectors of
mangroves over a period of 6 years in Karachi, KetiBundar/Karochan
and Shah Bundar regions. Average survival rates of new plantation
is around 81%.
